     FIELD OF THE INVENTION 
     This application relates generally to the field of exercise equipment and methods associated therewith. In particular, this application relates to executable controls and control methods associated with exercise machines. 
     BACKGROUND 
     Exercise has become an increasingly important aspect of daily life, and most exercise regimens commonly involve the use of elliptical machines, stationary bicycles, rowing machines, treadmills, or other exercise machines. Such exercise machines are typically designed for use in a gym or other exercise facility, and may be configured such that a user can participate in various exercise classes, training programs, or other activities using such machines. In particular, such exercise machines generally provide the user with one or more buttons, switches, knobs, levers, or other mechanisms that enable the user to control various parameters of the exercise machine during use. For instance, a treadmill may include one or more controls dedicated to increasing and decreasing an incline of the treadmill deck, increasing and decreasing a speed of the treadmill belt, or modifying other parameters of the treadmill as the user walks, jogs, sprints, or performs various other activities on the treadmill. Similarly, a stationary bicycle may include one or more controls dedicated to increasing and decreasing a braking resistance of a flywheel of the bicycle, increasing and decreasing a pedal speed or cadence of the bicycle, or modifying other parameters of the stationary bicycle during use. 
     While such controls are commonplace on treadmills, stationary bicycles, elliptical machines, and other known exercise machines, such controls can be challenging to use in some situations. For example, due to the dynamic nature of the motion-based activities typically performed on such exercise machines (e.g., running, cycling, etc.), it can be difficult for a user to manipulate such controls during a workout. Moreover, even if a user is able to manipulate such controls while running, cycling, or performing other motion-based activities, such controls may not be optimized for enabling the user to select a particular setting or other parameter of the exercise machine, with accuracy, as such motion-based activities are being performed. Additionally, such controls typically do not correspond to verbal cues, suggestions, directions, comments, or other performance commands uttered by an instructor during an exercise class being performed using the exercise machine. 
     Example embodiments of the present disclosure are directed toward addressing one or more of the deficiencies of known exercise machines noted above. 
     SUMMARY OF THE INVENTION 
     In an example embodiment of the present disclosure, a method includes capturing audio content and video content of an instructor performing an exercise class, identifying a performance command included in the audio content, the performance command being uttered by the instructor during the exercise class, and identifying a timestamp associated with the performance command. Such an example method also includes generating an executable control corresponding to the performance command, and generating a video file comprising the audio content, the video content, and the executable control. In such examples, playback of the video file causes display of the executable control at a part of the video file corresponding to the timestamp. Such a method also includes providing the video file to an exercise machine, via a network, based at least in part on a request received via the network. 
     In another example embodiment, a method includes providing a first video file to a plurality of exercise machines, the first video file including content associated with an exercise class. The method also includes receiving user data from the plurality of exercise machines, the user data including respective settings associated with a common performance metric, the respective settings being used on the plurality of exercise machines during playback of a particular part of the first video file. Such an example method further includes identifying a timestamp associated with the particular part of the first video file, and generating an executable control corresponding to the performance metric. The method also includes generating a second video file comprising the content and the executable control. In such an example method, playback of the second video file causes display of the executable control at a part of the second video file corresponding to the timestamp. 
     In yet another example embodiment, a method includes receiving a video file at an exercise machine via a network, the video file including content associated with an exercise class, and providing the content via a display associated with the exercise machine, wherein providing the content includes displaying an executable control included in the video file, via the display, during a particular part of the video file. Such an example method also includes receiving user data collected while the executable control is displayed, the user data including a first setting of the exercise machine selected by a user during the particular part of the video file. Such a method further includes determining a difference between the first setting and a second setting of the executable control, generating an accuracy metric based at least in part on the difference, and providing the accuracy metric via the display.

     DETAILED DESCRIPTION 
     The following description is presented to enable any person skilled in the art to make and use aspects of the example embodiments described herein. For purposes of explanation, specific nomenclature is set forth to provide a thorough understanding of the present invention. Descriptions of specific embodiments or applications are provided only as examples. Various modifications to the embodiments will be readily apparent to those skilled in the art, and general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present disclosure. Thus, the present disclosure is not intended to be limited to the embodiments shown, but is to be accorded the widest possible scope consistent with the principles and features disclosed herein. 
     Example embodiments of the present disclosure include exercise machines, networked exercise systems, and corresponding methods whereby one or more exercise devices, such as treadmills, rowing machines, stationary bicycles, elliptical trainers, or any other suitable equipment may be equipped with an associated local system that allows a user to fully participate in live or recorded exercise classes from any location that can access a suitable communications network. The example exercise machines of the present disclosure include one or more displays configured to provide various controls operable to change parameters of the exercise machines. In particular, the displays of the present disclosure may be configured to provide user interfaces that include one or more executable controls operable to modify respective parameters of the exercise machine while the user of the machine is participating in an exercise class and/or otherwise using the exercise machine. In some examples, such executable controls may correspond to verbal cues, suggestions, directions, comments, or other performance commands uttered by an instructor during an exercise class. In some examples, such executable controls may include a setting corresponding to a relatively specific instruction or command given by the instructor. In other examples, on the other hand, such executable controls may include a setting corresponding to a relatively vague or abstract command given by the instructor during the exercise class. Additionally or alternatively, such executable controls may correspond to user data received from a plurality of exercise machines, wherein the user data includes respective settings used on the plurality of exercise machines during playback of an exercise class. 
     Thus, the exercise machines, executable controls, and corresponding methods described herein, may enable a user to easily and accurately modify one or more parameters of an exercise machine while participating in an exercise class, and according to a control setting that is unique to the particular exercise class in which the user is participating. Various aspects of such exercise machines and executable controls will now be described in more detail. 
     Referring generally to  FIGS. 1 and 2 , in various example embodiments of the present disclosure, a local system  100  may include an exercise machine  102 , such as a treadmill, with integrated or connected digital hardware including one or more displays  104  for use in connection with an instructor-led exercise class and/or for displaying other digital content. While the exercise machine  102  may be described and/or otherwise referred to herein as a “treadmill  102 ,” as noted above, example exercise machines  102  of the present disclosure may be any suitable type of exercise machine, including a rowing machine, stationary bicycle, elliptical trainer, stair climber, etc. Accordingly, any of the examples described herein may be applicable to, incorporated in, performed by, and/or otherwise associated with a treadmill, rowing machine, stationary bicycle, elliptical trainer, stair climber, etc. For ease of description, however, an exercise machine  102  comprising a treadmill will be referred to below unless otherwise specified. 
     In various example embodiments, the one or more displays  104  may be mounted directly to the exercise machine  102  or otherwise placed within view of a user  106 . In various exemplary embodiments, the one or more displays  104  allow the user  106  to view content relating to a selected exercise class both while working out on the exercise machine  102  and while working out in one or more locations near or adjacent to the exercise machine  102 . In some examples, the exercise machine  102  may also include a hinge, joint, pivot, bracket  138  or other suitable mechanism to allow for adjustment of the position or orientation of the display  104  relative to the user  106  whether the user  106  is working out on the exercise machine  102 , or working out near or adjacent to the exercise machine  102 . 
     In example embodiments in which the exercise machine  102  comprises a treadmill, the exercise machine  102  may generally include a lower assembly  108  and an upper assembly  110 . The lower assembly  108  may generally include a deck  112  of the exercise machine  102  that provides support for the user  106  while the user  106  is working out on the exercise machine  102 , as well as other components of both the lower assembly  108  and the upper assembly  110 . For example, the deck  112  may support a first motor (not shown) of the exercise machine  102  configured to increase, decrease, and/or otherwise change an incline of the deck  112  relative to a support surface on which the exercise machine  102  is disposed. The deck  112  may also include one or more linkages  116  coupled to such a motor and configured to, for example, raise and lower the deck  112  by acting on the support surface when the motor is activated. The deck  112  may also include a second motor (not shown) configured to increase, decrease, and/or otherwise change a rotational speed of a belt  120  connected to the deck  112 . The belt  120  may be rotatable relative to the deck  112  and, in particular, may be configured to revolve or otherwise move completely around (i.e., encircle) the deck  112  during use of the exercise machine  120 . For example, in embodiments in which the exercise machine  102  comprises a treadmill, the belt  120  may support the user  106  and may repeatedly encircle the deck  112  as the user  106  runs, walks, and/or otherwise works out on the treadmill. Such an example belt  120  may include one or more continuous tracks (not shown) movably coupled to a gear, flywheel, pulley, and/or other component of the deck  112 . In such examples, such a gear, flywheel, pulley, and/or other component of the deck  112  may be coupled to an output shaft or other component of the second motor described above. In such examples, rotation of the output shaft or other component of the second motor may drive commensurate rotation of the belt  120 . 
     The belt  120  may also include a plurality of laterally aligned slats  126  connected to the one or more continuous tracks described above. For example, as shown in  FIG. 1 , each slat  126  may extend substantially parallel to at least one adjacent slat  126 . Additionally, each slat  126  may be hingedly, pivotally, and/or otherwise movably coupled to the one or more continuous tracks of the deck  120  via one or more respective couplings. Such couplings may comprise, for example, a bracket, pin, screw, clip, bolt, and/or one or more other fastening components configured to secure a respective slat  126  to the continuous track described above, while allowing the slat  126  to pivot, rotate, and/or otherwise move relative to the track while the belt  120  revolves about the deck  112 . 
     With continued reference to  FIG. 1 , the exercise machine  102  may also include one or more sidewalls  128  connected to the deck  112 . For example, the exercise machine  102  may include a first sidewall  128  on a left-hand side of the deck  112 , and a second sidewall  128  on the right-hand side of the deck  112 . Such sidewalls  128  may be made from cloth, foam, plastic, rubber, polymers, and/or other like material, and in some examples, the sidewalls  128  may assist in damping and/or otherwise reducing noise generated by one or more of the motors and/or other components of the deck  112 . 
     The exercise machine  102  may also include one or more posts  130  extending upwardly from the deck  112 . For example, the exercise machine  102  may include a first post  130  on the left-hand side of the deck  112 , and a second post  130  on the right-hand side of the deck  112 . Such posts  130  may be made from a metal, alloy, plastic, polymer, and/or other like material, and similar such materials may be used to manufacture the deck  112 , the slats  126 , and/or other components of the exercise machine  102 . In such examples, the posts  130  may be configured to support the display  104 , and in some examples, the display  104  may be directly coupled to a crossbar  132  of the exercise machine  102 , and the crossbar  132  may be connected to and/or otherwise supported by the posts  130 . For example, the crossbar  132  may comprise one or more hand rests or handles useful in supporting the user  106  during exercise. In some examples, the crossbar  132  may be substantially C-shaped, substantially U-shaped, and/or any other configuration. In any of the examples described herein, the crossbar  132  may extend from a first one of the posts  130  to a second one of the posts  130 . Further, in some examples, the posts  130  and the crossbar  132  may comprise a single integral component of the upper assembly  110 . Alternatively, in other examples, the posts  130  and the crossbar  132  may comprise separate components of the upper assembly  110 . In such examples, the upper assembly  110  may include one or more brackets  134 , endcaps  136 , and/or additional components configured to assist in coupling the one or more posts  130  to the crossbar  132 . 
     As noted above, the exercise machine  102  may also include a hinge, joint, pivot, bracket  138  and/or other suitable mechanism to allow for adjustment of the position or orientation of the display  104  relative to the user  106  whether they are walking, jogging, running, and/or otherwise working out on the exercise machine  102 , or working out near or adjacent to the exercise machine  102 . For example, such brackets  138  may include at least one component rigidly connected to the crossbar  132 . Such brackets  138  may also include one or more additional components rigidly coupled to the display  104 . In such examples, the components of the bracket  138  connected to the display  104  may be moveable, with the display  104  relative to the components of the bracket  138  connected to the crossbar  132 . Such components may include one or more dove-tail slider mechanism, channels, and/or other components enabling the display  104  to controllably slide and/or otherwise move relative to the crossbar  132 . Such components may also enable the user  106  to fix the position of the display  104  relative to the crossbar  132  once the user  106  has positioned the display  104  as desired. 
     As shown in  FIGS. 1 and 2 , the exercise machine  102  may also include one or more controls  144 ,  146  configured to receive input from the user  106 . The exercise machine  102  may further include one or more sensors  147  configured to sense, detect, and/or otherwise determine one or more performance parameters of the user  106  before, during, and/or after the user  106  participates in an exercise class using the exercise machine  102 . In any of the examples described herein, the controls  144 ,  146  and the one or more sensors  147  may be operably and/or otherwise connected to one or more controllers, processors, and/or other digital hardware  148  of the exercise machine  102 . 
     The digital hardware  148  (shown in phantom in  FIGS. 1 and 2 ) associated with the exercise machine  102  may be connected to or integrated with the exercise machine  102 , or it may be located remotely and wired or wirelessly connected to the exercise machine  102 .

In various exemplary embodiments these components may be connected to and/or otherwise integrated with the exercise machine  102 . All communications between and among such components of the digital hardware  148  may be multichannel, multi-directional, and wireless or wired, using any appropriate protocol or technology. In various exemplary embodiments, the digital hardware  148  of the exercise machine  102  may include associated mobile and web-based application programs that provide access to account, performance, and other relevant information to users from local or remote exercise machines, processors, controllers, personal computers, laptops, mobile devices, or any other digital device or digital hardware. In any of the examples described herein, the one or more controllers, processors, and/or other digital hardware  148  associated with the exercise machine  102  may be operable to perform one or more functions associated with control logic of the exercise machine  102 . Such control logic may comprise one or more rules, programs, or other instructions stored in a memory of the digital hardware  148 . For example, one or more processors included in the digital hardware  148  may be programmed to perform operations in accordance with rules, programs, or other instructions of the control logic, and such processors may also be programmed to perform one or more additional operations in accordance with and/or at least partly in response to input received via one or more of the controls  144 ,  146 , via one or more of the sensors  147 , and/or via various controls, user interfaces, or other components provided by the display  104 . In any of the examples described herein, the display  104  may comprise a touch screen, a touch-sensitive (e.g., capacitance-sensitive) display, and/or any other device configured to display content and receive input (e.g., a touch input, tap input, swipe input, etc.) from the user  106 . 
     In any of the examples described herein, one or more of the controls  144 ,  146  associated with the exercise machine  102  may comprise an infinity wheel-type control. Such a control may be useful in changing and/or otherwise controlling, for example, the incline of the deck  112 , the speed of the belt  120 , and/or other parameters of the exercise machine  102  associated with incremental increases or decreases. In an example embodiment, one or more of the controls  144 ,  146  associated with the exercise machine  102  may include a rotary dial connected to a corresponding rotary encoder. In such examples, the rotary encoder may include one or more detents or other components/structures that may be tuned for a desired incremental change in a corresponding parameter of the exercise machine  102 . For example, the rotary encoder may be tuned such that each detent thereof may correlate to a 0.5% increase or decrease in an incline angle of the deck  112 . Alternatively, the rotary encoder may be tuned such that each detent thereof may correlate to a 0.1 mph increase or decrease in a speed of the belt  120 . In still further examples, percentages, speeds, and/or other increments greater than or less than those noted above may be chosen. Additionally, one or more such controls  144 ,  146  may include one or more additional buttons, wheels, touch pads, levers, knobs, or other components configured to receive additional inputs from the user  106 , and such additional components may provide the user  106  with finer control over the corresponding parameters of the exercise machine  102 . One or more such controls  144 ,  146  may also include a respective control housing configured to assist in mounting the control  144 ,  146  to the crossbar  132  or other components of the exercise machine  102 . 
     With continued reference to  FIGS. 1 and 2 , in various example embodiments, the one or more sensors  147  of the exercise machine  102  may be configured to sense, detect, measure, and/or otherwise determine a range of user data, parameters of the exercise machine  102 , and/or other information, from both the exercise machine  102  and the user  106 , instantaneously and/or over time. For example, the exercise machine  102  may include one or more sensors  147  that measure the incline of the deck  112 , the speed of the belt  120 , a load applied to the deck  112 , the belt  120 , one or more of the motors described above, and/or other components of the exercise machine  102 , an amount of energy expended by the user  106 , a power output of the exercise machine  102 , user weight, steps, distance, total work, repetitions, an amount of resistance applied to the belt  120  by one or more of the motors described above and/or other components of the exercise machine  102 , a pedal cadence, a brake force or resistance, as well as any other information associated with, for example, a treadmill, a stationary bicycle, or other exercise machine  102 . The exercise machine  102  may also include sensors  147  to measure user heart-rate, respiration, hydration, calorie burn, or any other physical performance metrics, or to receive such information from sensors provided by (e.g., worn by) the user  106 . Where appropriate, such information can be calculated as current/instantaneous values, maximum, minimum, average, or total over time, or using any other statistical analysis. Trends can also be determined, stored, and displayed to the user, the instructor, and/or other users. Such sensors  147  may communicate with memory and/or processors of the digital hardware  148  associated with the exercise machine  102 , nearby, or at a remote location, using wired or wireless connections. Such sensors  147  and/or the processors of the digital hardware  148  may also communicate with one or more processors disposed remote from the exercise machine  102  using such wired or wireless connections. 
     In various exemplary embodiments, the exercise machine  102  may also include one or more indicators (not shown) to provide information to the user  106 . Such indicators may include lights, projected displays, speakers for audio outputs, or other output devices capable of providing a signal to a user  106  to provide the user  106  with information such as timing for performing an exercise, time to start or stop exercise, or other informational indicators. For example, such indicators (e.g., lights or projected displays) could display information regarding the number of sets and repetitions performed by the user  106  at a location where it can be seen by the user  106  during the performance of the relevant exercise. 
     With reference to  FIG. 2 , and as noted above, the display  104  of the exercise machine  100  may comprise and/or may be driven by a user input device such as a touchscreen, mouse, voice control, or other suitable input device. In some examples, the display  104  or at least a portion thereof, may comprise a touchscreen configured to receive touch input from the user  106 . The display  104  may be any size, but optimally are large enough and oriented to allow the display of a range of information including one or more video streams, a range of performance metrics corresponding to the user  106 , a range of additional performance metrics associated with one or more additional users exercising on exercise machines remote from the exercise machine  102 , and a range of different controls. In various exemplary embodiments, the display  104  may include some or all of its area that can reflect the image of the user  106  to provide user feedback regarding their form and performance of various activities. 
     In various exemplary embodiments the user  106  can use the display  104  or one or more user interfaces  200  displayed on the display  104  to selectively present a range of different information including live and/or archived video, performance data, and other user and system information. In any of the examples described herein, such user interfaces  200  can provide a wide range of control and informational windows that can be accessed and removed individually and/or as a group by a click, touch, voice command, or gesture. In various exemplary embodiments, such windows may provide information about the user&#39;s own performance and/or the performance of other participants in the same exercise class both past and present. 
     Example user interfaces  200  presented via the display  104  may be used to access member information, login and logout of the system  100 , access live content such as live exercise classes and archived classes or other content. User information may be displayed in a variety of formats and may include historical and current performance and account information, social networking links and information, achievements, etc. The user interfaces described herein can also be used to access the system  100  to update a user profile (e.g., a user profile that is unique to the user  106 ) or member information, manage account settings such as information sharing, and/or to modify one or more settings of a control included in the user interface  200 . 
     An example user interface  200  may also be presented on the one or more displays  104  to allow users to manage their experience, including selecting information to be displayed and arranging how such information is displayed on the display  104 . Such a user interface  200  may present multiple types of information overlaid such that different types of information can be selected or deselected easily by the user  106 . For example, performance metrics and/or other information may be displayed over video content using translucent or partially transparent elements so the video behind the information elements can be seen together with (i.e., simultaneously with) the performance metrics and/or other information itself. Further, example user interfaces  200  may present a variety of screens to the user  106  which the user  106  can move among quickly using the provided user input device, including by providing a touch input via the display  104 . 
     In any of the examples described herein, the processor and/or other components of the digital hardware  148  may control the display  104  and/or otherwise cause the display  104  to display the various user interfaces  200  of the present disclosure. For example, the processor or other components of the digital hardware  148  may cause the display  104  to display a user interface  200  comprising a home screen that provides basic information about the system  100  and/or the exercise machine  102 , as well as available options. Such a home screen may provide direct links to information such as scheduled classes, archived classes, a leaderboard, instructors, and/or profile and account information. The home screen may also provide direct links to content such as a link to join a particular class. The user  106  can navigate among the different portions of the home screen by selecting such links using the applicable input device such as by touching the display  104  at the indicated location, or by swiping to bring on a new screen. An example user interface  200  providing such a home screen may also provide other information relevant to the user  106  such as social network information, and navigation buttons that allow the user to move quickly among the different screens in the user interface  200 . 
     In various example embodiments, one or more of the user interfaces  200  may include various components configured to provide information to the user  106  while the user  106  is participating in an exercise class. For example, as will be described in greater detail below, one or more example user interfaces  200  may include a timeline  202  (e.g., a segmented timeline) indicating portions of an exercise class being displayed on the display  104 , and a position and/or location within the timeline corresponding to the current portion of the exercise class being displayed. An example user interface  200  may also include a scorecard  204 , leaderboard, or other component providing rankings, output, exercise machine parameters, user data, and/or other information related to other users participating in (either in real time, or previously) the exercise class being displayed on the display  104 . An example user interface  200  may further include various display bars  206  or other components providing performance metrics, performance information, and/or other user data associated with the user  106 . Such information may include, for example, various settings or other parameters of the exercise machine  102  (e.g., a current incline of the deck  112 , a current speed of the belt  120 , a current pedal cadence of a stationary bicycle, a current braking force or resistance of the stationary bicycle, etc.), an output of the user  106 , and/or other information corresponding to the user  106  participating in an exercise class. Additionally, in some examples the user interface  200  may include one or more executable controls  210  operable to modify an incline of the deck  112 , a speed of the belt  120 , a pedal cadence of a stationary bicycle, a braking force or resistance of the stationary bicycle, and/or other parameters of the exercise machine  102  while the user  106  is participating in an exercise class. As shown in at least  FIG. 2 , in such embodiments the timeline  202 , scorecard  204 , leaderboard, display bars  206 , executable controls  210 , and/or other components of the user interface  200  may be displayed on the display  104  together with (e.g., simultaneously with) content  208  comprising the exercise class that the use  106  is currently participating in. 
     In various exemplary embodiments, the user interfaces  200  described herein may be run through a local program or application using a local operating system such as an Android or iOS application, or via a browser-based system. Any of the performance metrics or other information described herein with respect to the various user interfaces  200  may also be accessed remotely via any suitable network such as the internet. For example, users  106  may be able to access a website from a tablet, mobile phone, computer, and/or any other digital device, and such users  106  may be able to review historical information, communicate with other participants, schedule classes, access instructor information, and/or view any of the information described herein with respect to the various user interfaces  200  through such a website. 
       FIG. 3  illustrates an example networked exercise system  300  of the present disclosure including one or more exercise machines  102  that are in communication via an example network. Such an example networked exercise system  300  may be used to, for example, capture and/or otherwise generate audio content, video content, and/or other content corresponding to an exercise class being performed by one or more instructors. The networked exercise system  300  may also be configured to generate a video file and/or any other electronic file, digital file, or the like comprising the captured audio content and video content. In some examples, the networked exercise system  300  may also be configured to generate one or more of the executable controls  210  described herein with respect to the user interface  200  ( FIG. 2 ), and to associate such executable controls with the video file such that playback of at least part of the video file by a processor of an exercise machine  102  (e.g., via a display  104  of the exercise machine  102 ) may result in the display of the executable control  210 . 
     In further examples, the networked exercise system  300  may also be configured to provide a video file (e.g., a video file including content associated with an exercise class) to a plurality of exercise machines, and to receive corresponding user data from the plurality of exercise machines. For instance, such user data may include respective settings associated with a common performance metric, and the respective settings may comprise settings selected and/or otherwise used by users on the plurality of exercise machines during playback of a particular part of the video file. In such examples, a processor, server, or other component of the networked exercise system may identify a timestamp associated with the particular part of the video file. In such examples, the processor, server, or other component may also generate an executable control corresponding to the performance metric, and may generate an additional video file that includes the content associated with the exercise class, and the executable control. In such examples, playback of the additional video file may cause display of the executable control at a part of the additional video file corresponding to the timestamp described above. In any of the examples described herein, content captured and/or distributed by the networked exercise system  300  may comprise live and/or archived exercise classes, live and/or archived instructional content such as video content explaining how to properly perform an exercise, scenic or map-based content, videos, and/or animations that can be rendered in three-dimensions from any angle may be created and stored in various local or remote locations and shared across the networked exercise system  300 . 
     In various example embodiments, the networked exercise system  300  may be managed through one or more networked backend servers  302  and may include various databases  304  for storage of user data, system information, performance information, archived content, etc. Example local systems  100  ( FIG. 1 ) may be in communication with the networked backend servers  302  via any appropriate network  306  (e.g., a content distribution network  306 ), including without limitation, the internet. As an example of an alternative distribution approach, in various exemplary embodiments the backend servers  302  could be eliminated and data could be communicated throughout the system in a distributed or peer-to-peer manner rather than via a central server network. In such a networked exercise system  300 , user data (e.g., performance data) may be broken up into small packets or “pieces” and distributed among user devices such that complete data sets are quickly distributed to all devices for display as required. 
     Content for distribution through the network  306  can be created in a variety of different ways. Content recording locations may include professional content recording studios, amateur and home-based locations, gyms, etc. In various exemplary embodiments, recording studios may include space for live instructor-led exercise classes with live studio participation, or may be dedicated studios with no live, in-studio participation. As shown in  FIG. 3 , recording equipment including one or more video cameras  308 , microphones  310 , mp3 players or other music players  312 , and/or other components and can be used to capture the instructor and/or participants during the class. Multiple cameras  308  can provide different views, and 3D cameras  308  can be used to create 3D content. In various exemplary embodiments, content may also be generated locally by users  106 . For example, exercise machines  102  may be equipped with recording equipment including microphones  310  and cameras  308 . Users  106  may generate live or recorded classes that can be transmitted, stored in or by the networked exercise system  300 , and distributed via the network  306 . 
     With continued reference to  FIG. 3 , class content (e.g., audio content and/or video content) may be generated by providing outputs of the one or more video cameras  308 , microphones  310 , and/or music players  312  as inputs to an audio mixer  314 . The audio mixer  314  may output content to an analog to digital converter  316 , which may provide converted data to a production switcher  318 . The production switcher  318  may send the production video to a video encoder  320 , which may store the encoded video to a local storage device  322 , and may also send it to a video transcoder  324 . 
     In some examples, the video encoder  320  may receive input from one or more users of the backend servers  302  comprising a command to associate an executable control  210  with the video file being created by the networked exercise system  300 . In such examples, the video encoder  320  may tag, save, embed, and/or otherwise associate such an executable control  210  with the video file, and at a desired location within the video file. Such a desired location may comprise and/or correspond to a timestamp associated with the input and/or associated with a particular part of the video file. Alternatively, the video encoder  320  and/or other components of the backend servers  302  may identify a verbal command from an instructor that is leading an exercise class. In such examples, the video encoder  320  and/or other components of the backend servers  302  may identify the verbal command included in audio content received from a microphone  310  and/or from a video camera  308 . Such a command may correspond to a parameter of an exercise machine  102  (e.g., an incline of the deck  112 , a speed of the belt  120 , a pedal cadence of a stationary bicycle, a braking force or resistance of the stationary bicycle, etc.). Additionally or alternatively, such a command may correspond to any other performance metric or parameter (e.g., a power zone, a stride type, a position of a seat associated with the exercise machine  102 , a stretching technique or form, etc.) associated with the exercise class being performed by the instructor. In such examples, the video encoder  320  and/or other components of the backend servers  302  may identify a timestamp associated with the command (e.g., a timestamp in the video content and/or the audio content corresponding to the command). In such examples, the video encoder  320  and/or other components of the backend servers  302  may associate the executable control  210  with the video file by linking the executable control  210  to a part of the video file corresponding to the timestamp. 
     Additionally in any of the examples described herein, the video encoder  320  and/or other components of the backend servers  302  may identify such a verbal command via natural language processing software or techniques. As will be describe in greater detail below, in still further examples, one or more such executable controls  210  may be generated based at least in part on user data received from a plurality of exercise machines  102 . In such examples, such user data may include respective settings associated with a common performance metric. For instance, such respective settings may be used on the plurality of exercise machines  102  during playback of a particular part of a video file comprising an exercise class (e.g., an archived exercise class or a live/real-time exercise class). In such examples, the video encoder  320  and/or other components of the backend servers  302  may identify a timestamp associated with the particular part of the video file, and may generate an executable control corresponding to the common performance metric noted above. In some such examples, the video encoder  320  and/or other components of the backend servers  302  may also generate an additional (e.g., a second) video file that includes audio and video content of the exercise class, as well as the executable control. Playback of such an additional video file may cause display of the executable control at a part of the additional video file corresponding to the timestamp. 
     Further, the video transcoder  324  may output transcoded data to a video packetizer  326 , which may then send a packetized data stream out through the network  306  to remote users  106 . In various exemplary embodiments, instructors and/or users  106  may be provided with access to a content creation platform that they can use to help them create content. Such a platform may provide tools for selecting and editing music, managing volume controls, pushing out chat or other communications to users  106 . 
     As described above with respect to  FIGS. 1 and 2 , through the display  104  and/or other user interface on their exercise machine  102 , users  106  may access lists, calendars, and schedules of live and recorded exercise classes available for delivery through the display  104 . In various exemplary embodiments, once the user  106  selects an exercise class, the local system  100  may access and/or display a primary data stream for the class. This primary data stream may include video, music, voice, text, or any other data, and may represent a live or previously recorded exercise class. The local system  100  may be equipped for hardware video accelerated encoding/decoding to manage high definition video quality at up to 1080 pixels based on existing technology. The local system  100  may automatically adjust bitrate/quality of the data stream for the class in order to bring participant the highest quality video according to user&#39;s bandwidth/hardware limitations. 
     In various exemplary embodiments, networked exercise systems  300  and methods of the present disclosure may include multi-directional communication and data transfer capabilities that allow video, audio, voice, and data sharing among all users  106  and/or instructors. This allows users  106  to access and display multi-directional video and audio streams from the instructor and/or other users regardless of location, and to establish direct communications with other users  106  to have private or conferenced video and/or audio communications during live or recorded classes. Such data streams can be established through the local system  100  for presentation via the one or more displays  104  via one or more of the user interfaces  200  described above. In various exemplary embodiments, users  106  can manage multiple data streams to select and control inputs and outputs. The local system  100  may allow the user  106  to control the volume of primary audio stream for the class as well as other audio channels for different users or even unrelated audio streams such as telephone calls or their own music selections. For example, this would allow a user  106  to turn down the instructor volume to facilitate a conversation with other users. 
     For live classes, in various exemplary embodiments the instructor may have the ability to communicate with the entire class simultaneously or to contact individual users, and solicit feedback from all users regardless of location in real-time. For example, instructors could ask users verbally, or text a pop-up message to users  106 , seeking feedback on difficulty level, music choice, terrain, etc. Users  106  could then respond through components of the local system  100  by selecting an appropriate response, or providing verbal feedback. This allows instructors to use crowdsourcing to tailor a class to the needs of the participants, and to improve their classes by soliciting feedback or voting on particular class features or elements. In any of the examples described herein, one or more of the executable controls described herein may comprise such a text or pop-up message to users  106  seeking feedback, providing guidance or encouragement, providing further instructions related to the exercise class, and/or providing any other information. 
     In various exemplary embodiments, instructors may also be able to set performance targets, and the system can measure and display to the user  106  and the instructor their performance relative to the target. For example, the instructor may set target metrics e.g. target power and speed, then display this next to users&#39; readings with a color coding to indicate whether or not the user is meeting this target. The system may allow the instructor to remotely adjust exercise machine settings for individual users  106 . In various exemplary embodiments, the exercise machine  102  may also automatically adjust based on information from the user  106 , the instructor, or based on performance. For example, the exercise machine  102  may adjust the difficulty to maintain a particular performance parameter such as heart rate within a particular range or to meet a particular performance target. Any of the executable controls described herein may be generated and/or configured to modify a parameter of the exercise machine  102  in order to assist the user  106  in meeting and/or exceeding such performance goals or targets. 
     With continued reference to  FIG. 3 , in various exemplary embodiments, the networked exercise system  300  described herein may allow users  106  to create accounts (e.g., user profiles) and save and manage their user data (e.g., performance data). As discussed above, the system may allow users  106  to browse schedules for upcoming live classes, signup for future live streaming classes, and setup reminders. Users  106  may also be able to invite others to participate in a live class, and setup text, email, voice, or other notifications and calendar entries. Users  106  may be able to access system, account, performance, and all other data via web-based or application based interfaces for desktop and/or mobile devices, in addition to the user interface for the local system  100  associated with their exercise machine  102 . 
     In various exemplary embodiments, the networked exercise system  300  can provide for simultaneous participation by multiple users in a recorded class, synchronized by the system and allowing access to all of the same communication and data sharing features that are available for a live class. With such a feature, the participants simultaneously participating in the same archived class can compete against each other, as well as against past performances or “ghost” participants for the same class. In some of the examples described herein, one or more executable controls may be generated and/or configured to modify a parameter of the exercise machine  102  in order to assist the user  106  in keeping pace with such past performances, “ghost” participants, and/or other performance goals or targets. 
     In some examples, the networked computer system  300  may be configured to feed synchronized live and/or archived video content and live and/or archived sensor data to users over the network  306 . In various exemplary embodiments, and as illustrated in  FIG. 3 , the networked exercise system  300  may be configured with a plurality of user exercise machines  102  in communication with the video content distribution network  306 . The user exercise machines  102  may also be in communication with various other networks and servers. Additionally, in any of the examples described herein, a control station (not shown) may provide signals via the network  306  to control the collection, storage, and management of data (e.g., user data, video content, audio content, parameters of the various exercise machines  102 , etc.) across the networked exercise system  300 . 
       FIG. 4  illustrates an example user interface  400  of the present disclosure, and the user interface  400  may be similar to and/or the same as the user interface  200  described above with respect to  FIG. 2 . In such examples, the user interface  400  may be provided to the user  106  during a selected exercise class. When an exercise class is being displayed, played back, and/or otherwise provided via the one or more displays  104  through the user interface  400 , in various exemplary embodiments the primary video feed may be shown as the background video full-screen or in a sub-window on the display  104 . Information elements may be provided on different parts of the display screen to indicate any performance metrics, including total time, elapsed time, time left, distance, speed (e.g., speed of the belt  120 ), mile pace of the user  106 , incline (e.g., incline of the deck  112 ), elevation, resistance, braking force, power, total work, energy expended (e.g., output), cadence (e.g., pedal cadence), power zone, heart rate, respiration, hydration, calorie burn, and/or any custom performance scores that may be developed. The displayed information may also include the trend or relationship between different performance metrics. For example, the display  104  can indicate a particular metric in a color that indicates current performance compared to average performance for an exercise class or over time, such as red to indicate that current performance of the user  106  is below average or green to indicate above average performance. Trends or relative performance can also be shown using color and graphics, such as a red down arrow to show that current performance is below average. The displayed information may further include settings, parameters, or other information (e.g., actual settings or settings requested by the instructor) related to the activity being performed during one or more segments of the exercise class (e.g., a setting or position of a seat of the exercise machine  102 , a stride type, a stretch position or form, etc.). 
     In various exemplary embodiments, the display  104  may also display information that supports or supplements the information provided by the instructor. Examples include one or more segmented timelines  402  that are illustrated together with at least part of the selected exercise class in the user interface  400 . As shown in at least  FIGS. 4 and 5 , an example segmented timeline  402  may include one or more segments  404   a ,  404   b ,  404   c  . . .  404   n  (collectively, “segments  404 ”) corresponding to respective portions, parts, or other exercise segments of the selected exercise class. The size, length, width, height, relative position, color, opacity, and/or other configurations of such segments  404  may be representative of, for example, the length of the corresponding portions or parts of the selected exercise class. The segmented timeline  402  may also provide an indication  406  of elapsed time and/or remaining time for the present workout segment and/or for the exercise class generally. The segmented timeline  402  may also include one or more visual indica  408   a ,  408   b ,  408   c  . . .  408   n  (collectively, “indicia  408 ”) indicating an activity requirement (e.g., run, jog, sprint, lift weights, etc.), an equipment requirement (e.g., dumbbells), and/or other requirement associated with a respective exercise segment of the selected exercise class. For example, the indicia  408   a  may indicate that the segment  404   a  comprises a walking segment, indicia  408   d  may indicate that the segment  404   c  comprises a running segment, and the indicia  408   b  may indicate that weights are required for at least part of the segment  404   a . In any of the examples described herein, such segmented timelines  402  may also include one or more lists or windows identifying and/or describing upcoming workout segments or features, instructional information such as graphics or videos demonstrating how to properly perform exercises, or other information relevant to the exercise class in progress. Such segmented timelines  402  may also provide and/or otherwise include information  409  indicating the current segment of the exercise class and/or the current activity that the instructor is requesting the user  106  perform. 
     As shown in at least  FIG. 4 , the user interface  400  may include a primary window  410  configured to show the live or archived exercise class or other content that the user  106  selected. In various exemplary embodiments, the user interface  400  may further include one or more performance metric windows  412  (e.g., the “scorecard” illustrated in  FIG. 4 ) overlaid on and/or otherwise displayed together with the primary window  410 . Such performance metric windows  412  may show a ranking, total output, current output, incline, belt speed, mile pace, one or more averages of such performance metrics, and/or other specific performance metrics for the user&#39;s current class, past classes, or other performance information. Such performance metric windows  412  may be presented anywhere on the display  104 , and may be user selectable such that they can be displayed or removed by a screen touch or gesture. 
     The user interface  400  may also allow the user  106  to toggle between display of maximum, average, and total results for different performance metrics. Additionally, the user interface  400  may allow the user  106  to hide or display information elements, including performance metrics, video streams, user information, etc. all at once or individually. Performance metrics and/or other performance information can also be displayed in various display bars  414 ,  416  that can be hidden or displayed as a group or individually. The user interface  400  may provide for complete controls for audio volume, inputs, and outputs as well as display output characteristics. 
     In any of the examples described herein, the user interface  400  may also include one or more executable controls  418 . Such executable controls  418  may be executable by a processor of the digital hardware  148  upon playback of a video file comprising audio and/or video content of an exercise class. For instance, upon playback of such a video file, the processor of the digital hardware  148  may provide one or more such executable controls  418  during particular portions of the exercise class at which an instructor utters and/or otherwise provides a corresponding performance command. In any of the examples described herein, such executable controls  418  may correspond to the performance command uttered by the instructor and may comprise visual indicia (e.g., text, images, etc.) indicating, embodying, and/or otherwise corresponding to the performance command. In such examples, such executable controls  418  may comprise pop-up messages or other means by which the instructor may enhance engagement with exercise class participants. In this way, such executable controls may effectively convey performance commands, a desired performance parameter/metric, words of encouragement, guidance, instructions, and/or other information to exercise class participants. In some examples, such executable controls  418  may comprise text windows, images, pop-up boxes, graphics, icons, or other visual content that may not be configured to receive an input (e.g., a touch input) from the user  106 . 
     In other examples, on the other hand, one or more executable controls  418  of the present disclosure may be configured to receive an input (e.g., a touch input) from the user  106 . In such examples, an executable control  418  may be operable to modify a parameter of the exercise machine  102  while the user  106  is participating in an exercise class. For example, such an executable control  418  may be configured to modify a speed of the belt  120  in accordance with a desired speed or pace identified by the instructor. In further examples, one or more executable controls  418  of the present disclosure may be configured to modify an incline of the deck  112 , a resistance associated with the belt  120 , a pedal cadence of a stationary bicycle, a braking force or resistance of the stationary bicycle, and/or other parameters of the exercise machine  102 . For example, in embodiments in which the exercise machine  102  comprises a treadmill, the user interface  400  may include one or more relatively specific and/or relatively descriptive executable controls  418  indicating a particular setting of the exercise machine  102  that will be implemented in response to an input received via the executable control  418 . For instance, the relatively specific and/or relatively descriptive executable control  418  shown in  FIG. 4  indicates that upon receipt of an input via the executable control  418 , the speed of the belt  120  will be adjusted to obtain a 6.0 minute mile pace. In other examples, on the other hand, one or more executable controls  418  provided by the user interface  400  may be relatively vague, nebulous, or nondescript. For instance, in some embodiments the user interface  400  may include a relatively vague “jog” executable control  418 , a “run” executable control  418 , a “sprint” executable control  418 , and/or other executable controls that do not specify a particular setting of the exercise machine  102 . Similar to the executable control  418  illustrated in  FIG. 4 , such relatively vague executable controls may be configured to receive one or more inputs from the user  106  while the user  106  is participating in an exercise class using the exercise machine  102 , and may be operable to modify the speed of the belt  120  and/or other settings or parameters of the exercise machine  102  based at least in part on such an input. 
     For instance, a relatively vague “jog” executable control  418  may be associated with a first speed of the belt  120  such that, upon receipt of a touch input via the executable control  418 , the processor, and/or other digital hardware  148  of the exercise machine  102  may control the motor of the deck  112  driving the belt  120  to cause the belt  120  to rotate about the deck  112 , at a speed corresponding to a jogging pace of the user  106 . In some examples, the speed associated with the relatively vague “jog” executable control  418  may be a default jogging pace stored in a memory of the digital hardware  148  and/or otherwise associated with the executable control  418 . Alternatively, in other examples the speed associated with the relatively vague “jog” executable control  418  may be customized, programmed, entered, and/or otherwise selected by the user  106 , when establishing a user profile unique to the user  106 , before the user  106  begins participating in the current exercise class, while the user  106  is participating in the exercise class, and/or at any other time. Accordingly, in such examples the user  106  may select a speed at which the user  106  desires the belt  120  to rotate when the user selects and/or otherwise, provides a touch input via the “jog” executable control  418 . In such examples, the speed of the belt  120 , and/or other parameter of the exercise machine  102  associated with the “jog” executable control  418  may be stored as part of the user profile of the user  106  in the memory associated with the digital hardware  148  and/or in, for example, the database  304  and/or other memory associated with the one or more servers  302  of the system  300  ( FIG. 3 ). 
     In still further examples, the speed associated with the relatively vague “jog” executable control  418  may be a speed that is identified, calculated, selected, and/or otherwise determined by, for example, the processor of the exercise machine  102 , and/or a processor or other component of the one or more servers  302 . In such further examples, the speed associated with the “jog” executable control  418  may be determined based on, for example, aggregate user data associated with past user selections, past user performances, or other previous workouts of the user  106 . In such examples, for instance, the processor and/or other digital hardware  148  of the exercise machine  102  may sense, collect, and/or otherwise determine user data including belt speeds that the user  106  commonly selects during participation in exercise classes using the exercise machine  102 . In such examples, the processor, and/or other digital hardware  148  of the exercise machine  102  may store such user data in a memory associated with the digital hardware  148 . The processor may also select, identify, and/or otherwise determine a belt speed frequently selected by the user  106  based at least in part on such user data, and may associate the selected speed with the “jog” executable control  418 . For instance, such a selected speed may be associated with a warm-up period/segment of previous exercise classes participated in by the user  106 , and such a speed may comprise a speed most frequently selected by the user  106  during such previous warm-up periods/segments. 
     In further examples, a speed of the belt  120  corresponding to such a relatively vague “jog” executable control  418  may be selected and/or indicated by the instructor of the exercise class either prior to the exercise class or during performance of the exercise class. In such examples, the one or more servers  302  may associate such a speed with the executable control  418  during generation of the executable control  418 . In still further examples, the speed of the belt  120  corresponding to such a “jog” control may comprise a mean, median, or mode belt speed included in user data received from a plurality of exercise machines  102  during one or more previous playbacks of the exercise class. It is understood that a “run” executable control  418 , a “sprint” executable control  418 , and/or any other relatively vague, nebulous, or nondescript executable controls  418  described herein may be configured in a similar fashion. 
     Relatively specific executable controls  418 , on the other hand (such as the executable control  418  illustrated in  FIG. 4 ), may include one or more settings that correspond to a specific performance command uttered by the instructor during the exercise class, one or more settings included in user data received from a plurality of exercise machines  102 , stored settings (e.g., settings stored in one or more user profiles), and/or settings based at least in part on information received from one or more additional sources. Further, although not illustrated in  FIG. 4 , it is understood that the user interface  400  may additionally or alternatively include one or more additional executable controls configured to modify an incline of the deck  112 , a pedal cadence, a power zone, a braking resistance, a belt resistance, and/or other parameters of the exercise machine  102 . In particular, such example executable controls may be configured to receive one or more inputs from the user  106  while the user  106  is participating in an exercise class using the exercise machine  102 , and such executable controls may be operable to modify the corresponding parameter of the exercise machine  102  based at least in part on such an input. One or more such executable controls may be configured through a process similar to that described above with respect to the executable control  418 . 
     Additionally, as noted above, any of the processes described herein with respect to configuring, generating, providing, causing the display of, and/or modifying one or more of the executable controls  418  of the present disclosure may be performed locally at the exercise machine  102  by the processor of the digital hardware  148 , remote from the exercise machine  102  by one or more processors of the server  302 , and/or by the processor of the digital hardware  148  operating in communication and/or in conjunction with one or more processors of the server  302 . 
     With continued reference to  FIG. 4 , in some examples the user interface  400  may include one or more additional windows  420 ,  422  and/or other portions configured to provide additional information to the user  106  during an exercise class. For example, in some embodiments the server  302  and/or the processor of the digital hardware  148  may receive user data collected while one or more of the executable controls  418  are displayed via the user interface  400 . In such examples, the received user data may include a first setting of the exercise machine  102  selected by the user  106  during a particular part of an exercise class being participated in using the exercise machine  102 . In such examples, the server  302  and/or the processor of the digital hardware  148  may determine a difference between such a first setting and a second setting of the displayed executable control  418 . The server  302  and/or the processor of the digital hardware  148  may also determine an accuracy metric based at least in part on the difference, and may provide the accuracy metric via, for example, one or more of the windows  420 ,  422  of the user interface  400  shown on the display  104 . 
     In such examples, an accuracy metric may comprise any number (e.g., a difference, an average, a mode, a median, etc.), parameter, or other indicator of how accurately or inaccurately the user  106  is following the performance command corresponding to the executable control  418 . Such an example accuracy metric (e.g., −3%) is shown in the window  420 . Additionally or alternatively, such an accuracy metric may comprise one or more graphics, images, figures, colors, flashing schema, or other visual indicia included in the window  420  to provide an indication of how accurately or inaccurately the user  106  is following the performance command corresponding to the executable control  418 . 
     In some examples, one or more of the windows  420 ,  422  included in the user interface  400  may also include, encouraging messages, explanations, comments, questions, dialogue (e.g., closed captioning), notifications, and/or other information provided by the instructor during the exercise class. Such an example encouraging message (e.g., “C&#39;mon, let&#39;s pick up the pace!”) is shown in the window  422 . Such a window  422  may also be configured to provide one or more notifications to the user  106  based at least in part on the accuracy metric described above. In some examples, such a window  422  may or may not be configured to receive an input (e.g., a touch input) from the user  106 . Such an example window  422  may be formed by any of the processes described above with respect to, for example, the executable control  418 . For example, the video encoder  320  and/or other components of the backend servers  302  may identify a verbal command from an instructor that is leading an exercise class. In such examples, the video encoder  320  and/or other components of the backend servers  302  may identify a verbal command, a message, a suggestion, an instruction, or other such utterance included in audio content received from a microphone  310  and/or from a video camera  308 . Such an utterance may correspond to a parameter of an exercise machine  102 , or alternatively, such an utterance may correspond to any other non-performance metric-based message associated with the exercise class being performed by the instructor. In such examples, the video encoder  320  and/or other components of the backend servers  302  may associate a window  422  providing such a message with a video file comprising the exercise class. In any of the examples described herein, the video encoder  320  and/or other components of the backend servers  302  may identify such a message via natural language processing software or techniques. Alternatively, in further examples, an operator of the system  300  may use the video encoder  320  and/or the server  302  to generate the window  422  manually. 
       FIG. 5  illustrates another example user interface  500  of the present disclosure. In such examples, the user interface  500  may be substantially similar to the user interface  400  described above with respect to  FIG. 4  and/or may be substantially similar to the user interface  200  described above with respect to  FIG. 2 . As shown in  FIG. 5 , such an example user interface  500  may include, among other things, a leaderboard  502  that is displayed so as to allow the user  106  to see his or her performance in comparison to other users participating in the same exercise class. In various exemplary embodiments, a leaderboard  502  may comprise a separate window overlaid on and/or otherwise displayed together with the primary window  410 . An example leaderboard  502  may be configured to display the relative performance of all participants, and/or of one or more subgroups of participants. For example, the user  106  may be able to select a leaderboard  502  that shows the performance of participants in a particular age group, male participants, female participants, male participants in a particular age group, participants in a particular geographic area, etc. For instance, in the example shown in  FIG. 5 , the leaderboard  502  has been configured to show the performance of a group of female participants in their 20&#39;s. Users  106  may have the ability to individually curate and/or otherwise configure a leaderboard  502 , or have the local system  100  curate a leaderboard  502  by selecting an appropriate group of participants relative to the user  106 . Users  106  may be able to curate their own leaderboards  502  for specific previously recorded classes to create a leaderboard  502  that provides the maximum personal performance incentive to the user  106 . 
     Users  106  may also be provided with the ability to deselect the leaderboard  502  entirely and remove it from the user interface  500 . In various exemplary embodiments, the exercise machine  102  may incorporate various social networking aspects such as allowing the user  106  to follow other participants, or to create groups or circles of participants. User lists and information may be accessed, sorted, filtered, and used in a wide range of different ways. For example, other users can be sorted, grouped and/or classified based on any characteristic including personal information such as age, gender, weight, or based on performance such as current power output, speed, or a custom score. 
     The leaderboard  502  may be fully interactive, allowing the user  106  to scroll up and down through the participant rankings, and to select a participant to access their detailed performance data, create a connection such as choosing to follow that participant, or establish direct communication such as through an audio and/or video connection. The leaderboard  502  may also display the user&#39;s personal best performance in the same or a comparable class, to allow the user  106  to compare their current performance to their previous personal best. In some examples, such performance information may also be displayed in one or more of the display bars  414 ,  416 . The leaderboard  502  may also highlight certain participants, such as those that the user  106  follows, or provide other visual cues to indicate a connection or provide other information about a particular entry on the leaderboard  502 . 
     In various exemplary embodiments, the leaderboard  502  may also allow the user  106  to view their position and performance information at all times while scrolling through the leaderboard  502 . For example, if the user  106  scrolls up toward the top of the leaderboard  502  such as by dragging their fingers upward on the display  104 , when the user  106  reaches the bottom of the leaderboard  502 , it may lock in position and the rest of the leaderboard  502  will scroll underneath it. Similarly, if the user  106  scrolls down toward the bottom of the leaderboard  502 , when the user&#39;s window reaches the top of the leaderboard  502 , it may lock in position and the rest of the leaderboard  502  will continue to scroll underneath it. In various exemplary embodiments, performance information about other users may also be presented on the leaderboard  502  or in any other format, including formats that can be sorted by relevant performance parameters. Users may elect whether or not to make their performance available to all users, select users, and/or instructors, or to maintain it as private so that no one else can view it. 
     As shown in  FIG. 5 , in some examples the leaderboard  502  may provide information  504  indicating the ranking of one or more of the users participating (currently or previously) in the present exercise class. Such a ranking may be, for example, a numerical ranking (e.g., 1-6,936 users, as indicated in the example leaderboard  502  of  FIG. 5 ) indicating the position, ranking, or rating of one or more of the users. Such ranking may be based on output, pace, speed, accuracy, or any of the other performance metrics described herein. In the example shown in  FIG. 5 , the leaderboard  502  may also include information  506  indicating the actual values associated with the rankings or other information  504 . For instance, in the example shown in  FIG. 5 , the user “Stephanie” may have a ranking of “3,” and this ranking for Stephanie may correspond to her output of 2,686 Watts. Similarly, the user “Ashley” may have a ranking of “4,” and this ranking for Ashly may correspond to her output of 1,890 Watts. Moreover, in some examples the leaderboard  502  may include information  508  indicating the accuracy with which each of the listed users are following the current instruction provided by the instructor. For instance, in the example shown in  FIG. 5 , the user “Stephanie” may have an accuracy rating of 13%, and such an accuracy rating may indicate that Stephanie is running at a pace that is 13% above the 6.0 minute mile pace that is currently being requested by the instructor (and as indicated by the executable control  418 ). Similarly, in the example shown in  FIG. 5 , the user “Ashley” may have an accuracy rating of 11%, and such an accuracy rating may indicate that Ashley is running at a pace that is 11% above the 6.0 minute mile pace that is currently being requested by the instructor (and as indicated by the executable control  418 ). While the leaderboard  502  shown in  FIG. 5  provides information  504  ranking the various users based on, for example, their respective output (as indicated by the information  506 ), it is understood that in further examples, the leaderboard  502  may rank the various users based on their respective accuracy rating (as indicated by the information  508 ), and/or based on any other performance metrics or other information. 
       FIG. 5A  illustrates another example user interface  500   a  of the present disclosure. In such examples, the user interface  500   a  may be substantially similar to the user interface  500  described above with respect to  FIG. 5  and/or may be substantially similar to the user interface  200  described above with respect to  FIG. 2 . As shown in  FIG. 5A , such an example user interface  500   a  may include, among other things, a primary window  410  that includes the segmented timeline  402 , leaderboard, display bars  414 ,  416 , and/or other items described above with respect to at least  FIG. 5 . Additionally, the example user interface  500  may include one or more windows  510 ,  516  overlaid on and/or otherwise displayed together with the primary window  410 . In such examples, the windows  510 ,  516  may include respective executable controls configured to receive inputs, and to direct a corresponding signal to the processor of the digital hardware  148  based at least in part on such inputs. In such embodiments, the processor of the digital hardware  148  may be configured to modify one or more corresponding parameters of the exercise machine  102  based at least in part on the signal and/or the input. 
     In some embodiments, one or more of the windows  510 ,  516  may correspond to a respective one of the parameters displayed, indicated, and/or identified by the display bar  414  or the display bar  416 . For example, the window  510  may be positioned above, below, near, integral with and/or otherwise in association with the “resistance” information provided in the display bar  414 . In such examples, the window  510  may include an executable control  512  configured to receive an input associated with and/or indicative of a desired increase in, for example, a resistance of the belt  120 . The window  510  may also include an executable control  514  configured to receive an input associated with and/or indicative of a desired decrease in the resistance of the belt  120 . In such examples, the executable controls  512 ,  514  may be configured to direct respective signals to the processor of the digital hardware  148  based at least in part on such inputs. 
     Similarly, as shown in  FIG. 5A  the window  516  may be positioned above, below, near, integral with and/or otherwise in association with the “cadence” information provided in the display bar  414 . In such examples, the window  516  may include an executable control  518  configured to receive an input associated with and/or indicative of a desired increase in, for example, a speed or cadence of the belt  120 . The window  516  may also include an executable control  520  configured to receive an input associated with and/or indicative of a desired decrease in the speed or cadence of the belt  120 . In such examples, the executable controls  518 ,  520  may be configured to direct respective signals to the processor of the digital hardware  148  based at least in part on such inputs. While example windows  510 ,  516  and corresponding executable controls  512 ,  514 ,  518 ,  520  have been described with respect to the resistance and cadence information provided by the user interface  500   a , it is understood that in other examples, the user interface  500   a  may include one or more additional windows and/or executable controls associated with any other information or parameters provided by the user interface  500   a.    
       FIG. 6  illustrates another example user interface  600  of the present disclosure. In implementations of this disclosure, the user interface  600  may be a workout summary interface. As illustrated, the user interface  600  may include a plurality of sections or windows, including a user identification window  602 , a workout window  604 , and a workout summary window  606 . Although the illustrated interface  600  includes the three windows  602 ,  604 ,  606 , more or fewer windows may be present in the interface. 
     The user identification window  602  may include information about the user. Such information may include, among other things, an identification of the user  106 , e.g., a picture, name, avatar, or the like, a number of followers the user  106  has, a number of fellow participants that the user  106  is following, the total lifetime runs, rides, circuits, or other workouts in which the user  106  has completed and/or been a participant, an identification of achievements or rewards the user has earned, records or goals, a timeline of the user&#39;s recent workout activity, and/or other such general information associated with the user  106  and/or the user&#39;s workout activities. In further examples, the information provided in the user identification window  302  may be provided in alternative formats, windows, or locations. 
     The workout window  604  may include information about workouts, including available classes and/or classes already completed by the user  106 . In some implementations, the workout window  604  may list upcoming live classes or available, pre-recorded on-demand classes. The workout window  604  may also include associated filters and/or search tools allowing the user  106  to customize the information contained in the workout window  604 . In the illustrated embodiment, the workout window  604  includes a listing of workouts or other exercise classes performed by the user  106 . The workouts are illustrated as arranged in a chronological list, although the workouts may be otherwise represented. Moreover, the workout window  604  may further include one or more of a score achieved by the user  106  during each exercise class (e.g., an output score), the date and/or time of the class, an identification of the instructor, and/or other information. The user interface  600  may also include one or more additional windows and/or other formats useful in providing additional information regarding the workout history of the user  106 . 
     The workout summary window  606  may provide information about a specific workout, including performance metrics indicative of the user&#39;s performance for the specific workout. For instance, the workout summary window  606  may include information about a completed workout selected in the workout window  604 . The workout summary window  606  may include workout information  608  indicative of the workout detailed in the workout summary window  606 . By way of non-limiting example, the workout information  608  may include one or more of a date, time, duration, workout name, instructor name, workout type (e.g., cycling, walking/running, combined workout, circuit workout, etc.) targeted muscle group(s) for the workout, and/or other information. 
     In some examples, the workout summary window  606  may also include at least part of the segmented timeline  402  described above with respect to  FIG. 4 . For instance, in the example user interface  600  illustrated in  FIG. 6  the summary window  606  may correspond to a treadmill-based circuit workout, and the illustrated segmented timeline  402  may include one or more segments  404   a ,  404   b ,  404   c  . . .  404   n  (collectively, “segments  404 ”) corresponding to respective portions, parts, or other segments of an exercise class. The segmented timeline  402  may also include visual indicia indicating an activity requirement (e.g., run, jog, sprint, lift weights, etc.), an equipment requirement (e.g., dumbbells, yoga mat, etc.) and/or other requirement associated with a respective segment of the exercise class. Together, the segments  404  and corresponding visual indicia of the segmented timeline  402  may provide a graphical representation of the entire workout. 
     The workout summary window  606  may also include one or more workout summary graphics  610 ,  612 ,  614  illustrated in association with the segments  404  of the segmented timeline  402 . For example, as shown in  FIG. 6  a first workout summary graphic  610  shows an output (e.g., a measure of performance, which may be a combination of one or more factors normalized across participants) for the user  106  over the duration of the workout, the second workout summary graphic  612  shows a speed for the user  106  over the duration of the workout, and the third workout summary graphic  614  the accuracy with which the user  106  followed various instructor commands over the duration of the workout. As illustrated, the workout summary graphics  610 ,  612 ,  614  may be rendered as graphs including respective plot lines  616   a ,  616   b ,  616   c  (collectively, “plot lines  616 ”) indicating user performance throughout the workout. The respective plot lines  616  may represent sensor information received from sensors associated with exercise equipment (e.g., the exercise machine  102 , body-worn sensors, etc.) used by the user  106 . For instance, speedometers, pedometers, accelerometers, position sensors, gyroscopes, biometric sensors, or the like, associated with the exercise machine  102  and/or with one or more wearable devices, may sense information associated with the exercise equipment and/or the user  106 , and such information may be used to create the respective plot lines  616 . 
     The workout summary graphics  610 ,  612 ,  614  may also include respective axes  618  representing an average value for the specific metric. In the illustrated implementations, the axes  618  represent a user-specific average (e.g., an average specific to the user  106 ) of the respective metrics, as determined based on the entire workout. However, in other embodiments, the axes  618  may indicate an average for all participants of the workout, e.g., so the user  106  can see her performance relative to other participants. In other implementations, the axes  618  may not be representative of an average, but may instead be a predetermined reference value, which may include a target value or a value associated with a previous undertaking of the workout. 
     In further examples, graphics other than the workout summary graphics  610 ,  612 ,  614  may also or alternatively be provided in the workout summary window  606 . For example, as illustrated in the graphic  612 , the user  106  may be able to select a “pace” graphic instead of the illustrated “speed” graphic. For example, such a pace graphic may show a minute-per-mile plot as opposed to the illustrated mile-per-hour. Moreover, the displayed and/or available workout summary graphics may vary based on the workout type and/or available information. For instance, workout summary graphics associated with weight-based segments of a workout may be rendered based on information from user-worn sensors or sensors disposed on weights used to perform those segments of the workout. Moreover, sensors on other types of equipment may also be used. By way of non-limiting example, a workout may include segments executed on a cycle, such as a stationary cycle. In such examples, sensors associated with the cycle may be used to render the workout summary graphics. Other modifications and alternatives may also be appreciated by those having ordinary skill in the art, with the benefit of this disclosure. 
       FIG. 6A  illustrates another example user interface  600   a  of the present disclosure. In such examples, the user interface  600   a  may be substantially similar to the user interface  600  described above with respect to  FIG. 6 . For instance, the user interface  600   a  may include, among other things, a user identification window  602 , a workout window  604 , a workout summary window  606 , workout information  608 , a segmented timeline  402 , and/or other components described above with respect to  FIG. 6 . 
     As shown in  FIG. 6 a   , in some examples the workout summary window  606  may include one or more workout summary graphics  620 ,  622  illustrated in association with the segments  404  of the segmented timeline  402 . For example, a workout summary graphic  620  may be indicative of a cadence of the user  106  (e.g., a cadence of the belt  120 ) over the duration of the workout, and an additional workout summary graphic  622  may be indicative of a resistance of the belt  120  over the duration of the workout. As illustrated, the workout summary graphics  620 ,  622  may be rendered as graphs including respective plot lines  616   d ,  616   e  indicating user performance throughout the workout. As described above with respect to  FIG. 6 , the respective plot lines  616   d ,  616   e  may represent sensor information received from sensors associated with exercise equipment (e.g., the exercise machine  102 , body-worn sensors, etc.) used by the user  106 , and in such examples, such information may be used to create the respective plot lines  616   d ,  616   e.    
     As described with respect to  FIG. 6 , the workout summary graphics  620 ,  622  may include respective axes  618  representing an average value for the specific metric. In the illustrated implementations, the axes  618  represent a user-specific average (e.g., an average specific to the user  106 ) of the respective metrics, as determined based on the entire workout. However, in other embodiments, the axes  618  may indicate an average for all participants of the workout, or may be a predetermined reference value (e.g., a target value). 
     In the example user interface  600   a  of  FIG. 6A , the workout summary graphics  620 ,  622  may also include respective visual indicia  624 ,  626  indicating average ranges associated with the respective metrics. For example, the visual indicia  624  may comprise a series of bars, boxes, line segments, shaded/hatched/colored areas, or other objects indicating an average cadence range associated with a corresponding segment of the workout. Likewise, the visual indicia  626  may comprise a series of bars, boxes, line segments, shaded/hatched/colored areas, or other objects indicating an average resistance range associated with a corresponding segment of the workout. Similar to the axes  618 , the visual indicia  624 ,  626  may comprise user-specific average ranges, average ranges determined based on all participants of the workout, predetermined reference ranges (e.g., target ranges), and/or other ranges of values corresponding to the particular workout identified by the workout information  608 . In any of the examples described herein, one or more of the workout summary graphics  620 ,  622  of the user interface  600   a  may also include information  628  indicating an amount of time, a percentage of the workout, and/or other indicia representing the user&#39;s adherence to, for example, a target range (e.g., a target cadence range) indicated by the visual indicia  624 . One or more of the workout summary graphics  620 ,  622  may also include information  630  indicating a user-specific best value (e.g., a best cadence, belt speed, etc.) for the workout corresponding to the parameter associated with the respective workout summary graphic  620 ,  622 . One or more of the workout summary graphics  620 ,  622  may further include information  632  indicating a user-specific average value (e.g., an average cadence, average belt speed, etc.) for the workout corresponding to the parameter associated with the respective workout summary graphic  620 ,  622 . 
       FIG. 7  illustrates still another example user interface  700  of the present disclosure. Such an example user interface  700  may include a window  702  showing a variety of pre-workout information  704  that may be useful to a user  106  when selecting a particular workout. For example, such information  704  may assist the user  106  in comparing a particular workout to various other available workouts so that the user  106  may select a workout based on difficulty level, activities included in the workout (e.g., workout content), and/or other criteria. As shown in  FIG. 7 , such information  704  may include a plurality of metrics  706  associated with the particular exercise class. Such metrics  706  may include, among other things, a difficulty ranking, an indication of various exercise equipment needed to participate in the class (e.g., an icon, image, text, or other indicia of a dumbbell, a yoga mat, etc.) an average rating, an average accuracy, and/or other metrics associated with (e.g., descriptive of) the exercise class. In some examples, such information  704  may also include an indication (e.g., an icon, image, text, or other indicia) of various muscle groups or other areas (e.g., arms, legs, cardio, abs, core, etc.) that the exercise class will focus on. 
     Additionally or alternatively, the information  704  may include a class plan  708  providing a breakdown of the different activities (e.g., jog, run, walk stretch, lift, etc.) included in the exercise class, a length of time associated with each respective activity, an icon, image, symbol, or other visual indicia associated with each activity, etc. In some examples, such a class plan  708  may also include a listing, summary, or other indication of the respective executable controls included in the exercise class and corresponding to the different segments of the exercise class. For example, the exercise class corresponding to the example class plan  708  may have an 11-minute run segment that includes a “6.0” minute mile pace executable control  418 . The exercise class corresponding to the example class plan  708  may also have a 10-minute run segment that includes a “6.0” minute mile pace executable control  418 . It is understood that such executable controls may be generated based at least in part on respective performance commands uttered by an instructor during the exercise class and/or based at least in part on user data including respective settings (associated with a common performance metric) used on a plurality of exercise machines during playback of the exercise class. In some examples, such a class plan  708  may further include one or more indications  710 ,  712 ,  714  of an accuracy metric associated with segments of the exercise class. For example, the indication  712  may indicate that, on average, previous users participating in the exercise class corresponding to the class plan  708  achieved an accuracy rating/metric of 5.0% when the “6.0” minute mile pace executable control  418  was provided (e.g., during the 11-minute run segment). Similarly, the indication  714  may indicate that, on average, previous users participating in the exercise class achieved an accuracy rating/metric of 5.0% when the “6.0” minute mile pace executable control  418  was provided during the 10-minute run segment. A user  106  considering participating in the exercise class may find the information  704  included in the window  702  useful in determining whether the particular exercise class is appropriate for her. Such information may also be useful in evaluating the difficulty and/or accuracy of the various executable controls  418  provided during the exercise class. 
       FIG. 7A  illustrates yet another example user interface  700   a  of the present disclosure. The user interface  700   a  may be substantially similar to the user interface  700  described above with respect to  FIG. 7 , and may include one or more substantially similar components. For instance, the example user interface  700   a  may include a window  702   a  showing a variety of pre-workout information  704  that may be useful to a user  106  when selecting a particular workout. As shown in  FIG. 7 a   , such information  704  may include a plurality of metrics  706  associated with the particular exercise class. Such metrics  706  may include, among other things, a difficulty ranking, an indication of various exercise equipment needed to participate in the class (e.g., an icon, image, text, or other indicia of a dumbbell, a yoga mat, etc.) an average rating, an average accuracy, and/or other metrics associated with (e.g., descriptive of) the exercise class. Additionally or alternatively, the information  704  may include a class plan  708  providing a breakdown of the different activities (e.g., jog, run, walk stretch, lift, etc.) included in the exercise class, a length of time associated with each respective activity, an icon, image, symbol, or other visual indicia associated with each activity, etc. In some examples, the class plan  708  may include an indication (e.g., an icon, image, text, or other indicia) of various muscle groups or other areas (e.g., arms, legs, cardio, abs, core, etc.) that the exercise class will focus on. 
     As shown in  FIG. 7A , the information  704  may also include one or more target metrics  716  associated with the exercise class. For instance, such target metrics  716  may include a target cadence plot, a target cadence range, an average cadence/belt speed, and/or other target cadence information  718  corresponding to the exercise class. Such target metrics  716  may also include a target resistance plot, a target resistance range, an average resistance value, and/or other target resistance information  720  corresponding to the exercise class. It is understood that the target cadence information  718  may correspond to one or more of the visual indicia  624  described above with respect to  FIG. 6A . Likewise, the target resistance information  720  may correspond to one or more of the visual indicia  626  described above with respect to  FIG. 6A . In some examples the information  704  provided by the window  702   a  may further include an indication  722  of the number of members or other users  106  currently working out and/or otherwise participating in the exercise class corresponding to the information  704 . 
       FIG. 7B  illustrates portions of the user interface  700   a  in further detail. For instance, as shown in  FIG. 7B , the user interface  700   a  may comprise a window  702  providing the pre-workout information  704 , metrics  706 , target metrics, and/or indication  722  of the number of members or other users  106  currently participating in the exercise class, as described above with respect to  FIG. 7A . Additionally, as shown in  FIG. 7B , the user interface  700   a  may provide an indication  724  of the number of friends (e.g., linked/stored/affiliated friends of the user  106 ) that have taken the particular exercise class in the past. Such an indication  724  may also indicate whether the particular user  106  has taken the exercise class in the past and/or a number of times the user  106  has taken the exercise class. 
       FIG. 8  illustrates a flow chart depicting another example method  800  of the present disclosure. The example method  800  is illustrated as a collection of steps in a logical flow diagram, which represents operations that can be implemented in hardware, software, or a combination thereof. In the context of software, the steps represent computer-executable instructions stored in memory. When such instructions are executed by, for example, the processor of the digital hardware  148  and/or by one or more processors of the server  302  described above, such instructions may cause the processor of the digital hardware  148  and/or the one or more processors of the server  302  to perform the recited operations. The order in which the operations are described is not intended to be construed as a limitation, and any number of the described steps can be combined in any order and/or in parallel to implement the process. Additionally, the method  800  may include any of the operations described herein with respect to additional and/or other methods of the present disclosure, and vice versa. For discussion purposes, and unless otherwise specified, the method  800  is described with reference to the networked exercise system  300 , an instructor using a first exercise machine  102  to perform an exercise class in a studio or other location comprising one or more of the video cameras  308 , microphones  310 , and/or other components of the networked exercise system  300 , a user  106  using a second exercise machine  102 , one or more user interfaces  200 ,  400 ,  500 ,  600 ,  700 , and/or other items shown in  FIGS. 1-7 . In particular, although any part of and/or the entire method  800  may be performed by the processor of the digital hardware  148 , unless otherwise specified, the method  800  will be described below with respect to the one or more processors of the server  302 , and/or other components of the networked exercise system  300  for ease of description. 
     With reference to  FIG. 8 , at  802  the server  302  and/or other components of the networked exercise system  300  may capture content associated with an exercise class being performed by an instructor. In such examples, the instructor may be utilizing a first exercise machine  102  to perform the exercise class in a studio, gym, and/or other workout facility. In such examples, one or more video cameras  308 , microphones  310 , music players  312 , audio mixers  314 , and/or other components of the networked exercise system  300  may be utilized by and/or in conjunction with the server  302  to sense, record, and/or otherwise capture the exercise class content at  802 . For example, at  802  the server  302  may capture audio content corresponding to the exercise class being performed by the instructor, as well as video content corresponding to the exercise class. 
     At  804 , the server  302  may generate a video file comprising the audio content, the video content, and/or any other content captured at  802 . For example, audio content may be captured at  802  in an audio track, and video content may be captured at  802  in a video track separate from the audio track. In such examples, at  804  the analog to digital converter  316 , the video encoder  320 , the video transcoder  324 , and/or other components of the server  302  may merge the audio track and the video track to form a single digital video file at  804 . Additionally or alternatively, the audio content and the video content may be captured at  802  utilizing at least one analog device. In such examples, at  804 , the analog to digital converter  316  and/or other components of the server  302  may convert any such analog content to digital content, and may generate a digital video file at  804  comprising digital audio content and digital video content. In still further examples, at  802 , the audio content and the video content may be captured in digital form and in a single content capture (e.g., digital recording) process. In such examples, a video file (e.g., a digital video file) may be generated at  802  upon and/or as part of capturing the audio content and video content. 
     At  806 , the server  302  may identify one or more performance commands (e.g., a performance command included in the audio content captured at  802 ) uttered by the instructor during the exercise class. For example, natural language processing software and/or other voice recognition software operating on the server  302  may identify a verbal command uttered by the instructor during the exercise class, and/or after the exercise class has been completed. In such examples, at  806  the natural language processing software and/or other voice recognition software may provide an indication of the verbal command to the video encoder  320 , and/or other components of the server  302  operable to generate an executable command. In some examples, the natural language processing software and/or other voice recognition software may additionally or alternatively provide the indication of the verbal command to one or more operators of the server  302  (e.g., via a display or other output device operably connected to the server  302 ), and such operators may confirm, for example, the accuracy of the identified verbal command and/or the placement of a corresponding executable control within the video file generated at  804 . In still further examples, at  806  the performance command may be identified and/or recognized by an operator viewing the exercise class (in real time and/or upon playback of the exercise class) without the use of natural language processing software and/or other voice recognition software. 
     As noted above, in some embodiments the instructor may utter a relatively specific performance command during an exercise class. Examples of such relatively specific performance commands may include, “run at a 6.0 minute mile pace,” “go to a 5.0 incline,” “reach your Zone 4 power output for the next 2 minutes,” or any other relatively definite command corresponding to a desired speed of the belt  120 , a desired running speed of the user  106 , a desired incline of the deck  112 , a desired power zone of the user  106 , a desired output level of the user  106 , a desired braking force or resistance of the exercise machine  102 , a position of a seat associated with the exercise machine  102 , a stride type, a pedal cadence of the user  106 , and/or any other such parameter. In such examples, at  806  the server  302 , an operator of the server  302 , and/or any other operator of a control station associated with the location (e.g., a studio) in which the instructor is performing the exercise class, may identify the verbal command uttered by the instructor. In some examples, at  806  natural language processing software and/or other voice recognition software operating on the server  302  may provide an indication of the verbal command to the video encoder  320 , and/or other components of the server  302  operable to generate an executable command. Additionally, at  806  the server  302  may identify a timestamp associated with the command (e.g., an elapsed time in the video file generated at  804 ). Such a timestamp may identify the time during the exercise class at which the instructor uttered the command. 
     In additional embodiments, the instructor may utter a relatively abstract or vague command during an exercise class. Examples of such relatively abstract or vague commands may include, “jog for a few minutes,” “let&#39;s go up this hill,” or any other command that may have a different meaning for respective users  106  participating in the exercise class, but that may still correspond to the current exercise segment and/or current part of the exercise class being performed by the instructor. In such examples, at  806  the server  302 , an operator of the server  302 , and/or an operator of a control station associated with the location (e.g., an exercise studio) in which the instructor is performing the exercise class, may identify the relatively abstract verbal command uttered by the instructor. In some examples, at  806  natural language processing software and/or other voice recognition software operating on the server  302  may provide an indication of the verbal command to the video encoder  320 , and/or other components of the server  302  operable to generate an executable command. Additionally, at  806  the server  302  may identify a timestamp associated with the relatively abstract command. 
     At  808 , the server  302  may generate an executable control  418  corresponding to the exercise class being performed by the instructor. As noted above, in some examples, one or more executable controls  418  generated at  808  may be operable to modify a parameter of an exercise machine  102  (e.g., a second exercise machine  102  used by a user  106  to participate in the exercise class). For example, at  808  the server  302  may generate an executable control  418  corresponding to the performance command identified at  806 . One or more executable controls  418  generated at  808  may comprise data files, text files, digital files, metadata, instructions, and/or any other electronic file executable by the processor of the digital hardware  148 . When an example executable control  418  generated at  808  is executed by the processor of the digital hardware  148 , the processor may cause display of the text or other information associated with the executable control  418  via a user interface (e.g., user interface  400 ). In some examples, such text (e.g., guidance, an encouraging statement, etc.) may be displayed via one or more respective windows  422  included in the user interface  400 . In some examples, such windows  422 , executable controls  418 , and/or other portions of the example user interfaces  400  described herein may be provided to the user  106  during an exercise class as a means of communicating with, guiding, and/or encouraging the user  106 . In some examples, such windows  422  and/or executable controls  418  may not be configured to receive user input and may not be operable to modify on or more parameters of the exercise machine  102 . In additional examples, on the other hand, one or more of the executable controls  418  described herein may be configured to receive a touch input from the user  106  via the display  104 . In such examples, the one or more of the executable controls  418  may be configured to modify at least one parameter of the second exercise machine  102  (e.g., the exercise machine  102  that the user  106  is utilizing to participate in the exercise class), based at least in part on such an input. In example embodiments of the present disclosure, one or more of the executable controls  418  generated at  808  may comprise one or more settings associated with modifying a parameter of the second exercise machine  102 . 
     For example, in embodiments in which the command identified at  806  comprises a relatively specific command, the server  302  may configure the executable control  418  such that, when the executable control  418  is processed and/or executed by the processor of the digital hardware  148  (e.g., of the second exercise machine  102 ), the processor of the digital hardware  148  may cause a component of the exercise machine  102  (e.g., a motor of the deck  112  controlling the speed of the belt  120 ) to operate and/or perform an action specifically defined by the executable control  418 . For example, in embodiments in which an example relatively specific command identified at  806  comprises “run at a 6.0 minute mile pace,” at  808  the server  302  may generate a corresponding executable control  418  that includes instructions, metadata, and/or other information or components which, when executed by the processor of the digital hardware  148 , will cause the motor of the deck  112  controlling the speed of the belt  120  to drive the belt  120  to rotate at a belt speed corresponding to a 6.0 minute mile pace. Similar instructions may be included in an executable control  418  directed to a particular power zone, a particular incline of the deck  112 , a particular pedal cadence, a particular stationary bicycle braking resistance, and/or any other parameter of the exercise machine  102 . 
     On the other hand, in embodiments in which the command identified at  806  comprises a relatively vague or abstract command, the server  302  may configure the executable control  418  such that, when the executable control  418  is processed and/or executed by the processor of the digital hardware  148  (e.g., of the second exercise machine  102 ), the processor of the digital hardware  148  may determine an appropriate (e.g., a best fit) response corresponding to the executable control  418  before causing one or more components of the exercise machine  102  to operate in a modified manner. For example, in embodiments in which an example relatively abstract command identified at  806  comprises “jog for a few minutes,” at  808  the server  302  may generate an executable control  418  including instructions, metadata, and/or other information which when executed by a processor of an exercise machine  102  (e.g., a second exercise machine  102 ) may cause the belt  120  of such an exercise machine  102  to rotate at a 4.0 minute mile pace, and/or at any other relatively common jogging pace, and such a setting of the executable control  418  may comprise a default setting. Such a default setting may be associated with the executable control  418  at  808  in situations in which relatively little user data is available corresponding to the particular user  106 , a user profile of the user  106  does not include user data associated with a setting or preference of the user  106  related to the abstract command identified at  806 , and/or in any other situation in which the server  302  does not have access to adequate information corresponding to the user  106 . Alternatively, in examples in which a user profile of the user  106  identifies a preferred jogging pace, and/or in which the database  304  includes stored user data or other information indicating previously selected, previously customized, and/or previously entered jogging speeds of the particular user  106 , a weight, height, age, gender, or other physical characteristics of the user  106 , and/or other such information, at  808  the server  302  may generate an executable control  418  configured to cause the belt  120  to rotate at a jogging pace that corresponds to such user-specific information. 
     In any of the examples described herein in which a relatively vague or abstract command has been identified, the server  302  may generate an executable control  418  at  808  corresponding to such a command, and upon receiving a touch input via the executable control  418  while the exercise class is being presented to the user  106  via the user interface  500 , the processor of the digital hardware  148  may determine an appropriate response (e.g., an appropriate modification of one or more parameters of the exercise machine  102 ) based on user data stored within a memory of the digital hardware  148  and/or stored within the database  304  associated with the server  302 . As noted above, such an appropriate response, may comprise a default setting (e.g., a default jogging speed, and/or a default deck incline associated with jogging), a previously selected, previously customized, and/or previously entered setting (e.g., a jogging speed and/or a jogging deck incline included in the user profile of the user  106 ), and/or a setting that is determined by the processor of the digital hardware  148  and/or by the processor of the server  302  based at least in part on user data (e.g., aggregate user data corresponding to the user  106  participating in one or more previous exercise classes using the exercise machine  102 ) stored within a memory of the digital hardware  148  and/or stored within the database  304 . 
     At  810  the server  302  may embed, link, and/or otherwise associate the executable control  418  with the video file generated at  804  such that playback of at least part of the video file by the processor of the digital hardware  148  (e.g., by the processor of the second exercise machine  102 ) via the display  104  may result in display of the executable control  418 . In particular, at  810  the server  302  may link the executable control  418  to a part of the video file corresponding to the timestamp associated with the command and identified at  806 . In such examples, the timestamp may comprise an elapsed time of the video file generated at  804  and/or during the exercise class at which the instructor uttered the command. As a result, when providing the exercise class to the user  106  via the user interface  500  (e.g., either in substantially real time via live streaming, and/or upon playback of the exercise class using an archived video file), the processor of the digital hardware  148  (e.g., the processor of the second exercise machine  102 ) may provide the executable control  418  at the point in time during the exercise class in which the instructor uttered the verbal command. 
     At  812 , the server  302  may provide the executable control  418 , together with the video file generated at  804 , to the processor of the digital hardware  148 . In such examples, the video packetizer  326  of the server  302  may provide one or more signals to the exercise machine  102  (e.g., the second exercise machine  102 ) via the network  306 , and such signals may include, at least part of the video file and/or the executable control  418  embedded therein. In some examples, such as an example in which a user  106  is live streaming the exercise class in substantially real-time, the server  302  may provide the video file generated at  804  and the executable control  418  generated at  808 , via the network  306 , as part of a live stream of the exercise class. Alternatively, in examples in which the user  106  is participating in an archived exercise class, at  812 , the server  302  may provide the video file generated at  804  and the executable control  418  generated at  808 , via the network  306 , as part of a transmission of the archived exercise class. 
     Further, at  814 , the server  302  may save and/or otherwise store the executable control  418  generated at  808  together with the video file generated at  804 . In such examples, the executable control  418  may be linked to, embedded within, associated with, and/or otherwise stored with the video file such that, upon playback of the video file, the executable control  418  may be displayed as part of a user interface  500  presented to the user  106  via the display  104 . Further, while the previous disclosure indicates that the server  302  may perform one or more operations of the method  800 , in any of the examples described herein, any of the operations described above with respect to the method  800  may be performed, in whole or in part, by the server  302 , an operator of the server  302 , an operator of a control station at which an exercise class is being performed by an instructor, and/or by any combination thereof. 
       FIG. 9  illustrates a flow chart depicting another example method  900  of the present disclosure. Similar to the method  800  described above, the example method  900  is illustrated as a collection of steps in a logical flow diagram, which represents operations that can be implemented in hardware, software, or a combination thereof. In the context of software, the steps represent computer-executable instructions stored in memory. When such instructions are executed by, for example, the processor of the digital hardware  148  and/or by one or more processors of the server  302  described above, such instructions may cause the processor of the digital hardware  148  and/or the one or more processors of the server  302  to perform the recited operations. Such computer-executable instructions may include routines, programs, objects, components, data structures, and the like that perform particular functions or implement particular abstract data types. The order in which the operations are described is not intended to be construed as a limitation, and any number of the described steps can be combined in any order and/or in parallel to implement the process. For discussion purposes, and unless otherwise specified, the method  900  is described with reference to the local system  100 , the exercise machine  102 , the user  106 , the user interfaces  200 ,  400 ,  500 ,  600 ,  700 , and/or other items shown in  FIGS. 1-7 . In particular, although any part of and/or the entire method  900  may be performed by the one or more processors of the server  302 , and/or other components of the networked exercise system  300 , unless otherwise specified, the method  900  will be described below with respect to the processor of the digital hardware  148  for ease of description. 
     With reference to  FIG. 9 , at  902  the processor of the digital hardware  148  may receive, at an exercise machine  102  and via the content distribution network  306  described above, a video file including content associated with an exercise class. For example, such a video file may include audio content and video content associated with an instructor performing an exercise class via an additional (e.g., a remote) exercise machine  102 . In such examples, the instructor may be utilizing an exercise machine  102  to perform the exercise class in a studio, gym, and/or other workout facility. In such examples, one or more video cameras  308 , microphones  310 , music players  312 , audio mixers  314 , and/or other components of the networked exercise system  300  may be utilized by and/or in conjunction with the server  302  of the networked exercise system  300  described above to sense, record, and/or otherwise capture the exercise class content included in the received video file. Additionally, as noted above with respect to at least the method  800  of  FIG. 8 , the video file may include, among other things, one or more executable controls. Further, in some examples the processor of the digital hardware  148  may receive the video file at  902  via a live stream of the exercise class. In such examples, the instructor may perform the exercise class in the workout facility described above, and the processor of the digital hardware  148  may receive the video file at  902  substantially simultaneously (e.g., in substantially real-time). Alternatively, the video file received at  902  may comprise a stored recording of an exercise class previously performed by the instructor, and in such examples, the processor of the digital hardware  148  may receive the video file at  902  at a later time and/or date. 
     At  904 , the processor of the digital hardware  148  may provide the content included in the video file via a display  104  associated with the exercise machine  102  being utilized by a user  106  wishing to participate and/or participating in the exercise class. For example, as noted above, one or more displays  104  may be mounted directly to the exercise machine  102  or otherwise placed within view of a user  106 . In various exemplary embodiments, the one or more displays  104  allow the user  106  to view content relating to a selected exercise class both while working out on the exercise machine  102  and while working out in one or more locations near or adjacent to the exercise machine  102 . The display  104  may comprise a touch screen, a touch-sensitive (e.g., capacitance-sensitive) display, and/or any other device configured to display content and receive input (e.g., a touch input, tap input, swipe input, etc.) from the user  106 . 
     Accordingly, providing the content at  904  may include playing back (e.g., displaying) the exercise class via the display  104  and/or via one or more speakers associated with the display  104  or the exercise machine  102 . Providing the content at  904  may also include displaying one or more executable controls  418  included in the video file, via the display  104 , during a particular part of the video file. For example, as noted above with respect to the method  800 , the server  302  may generate an executable control  418  corresponding to the exercise class being performed by the instructor. For example, the server  302  may generate an executable control  418  corresponding to a performance command uttered by the instructor as the instructor performs the exercise class. Alternatively, the server may generate an executable control  418  based at least partly on user data received from a plurality of exercise machines and associated with a common performance metric. Such executable controls  418  may be embedded within and/or otherwise associated with the video file received at  902 . When such an executable control  418  is executed by the processor of the digital hardware  148  at  904 , the processor of the digital hardware  148  may cause display of the text or other information associated with the executable control  418  via a user interface (e.g., user interface  400 ). In some examples, such text (e.g., guidance, an encouraging statement, etc.) may be displayed via one or more respective windows  422  included in the user interface  400 . In some examples, such windows  422 , executable controls  418 , and/or other portions of the example user interfaces  400  described herein may be provided to the user  106  during an exercise class as a means of communicating with, guiding, and/or encouraging the user  106 . In some examples, such windows  422  and/or executable controls  418  may not be configured to receive user input and may not be operable to modify on or more parameters of the exercise machine  102 . In additional examples, on the other hand, one or more of the executable controls  418  provided at  904  may be configured to receive a touch input from the user  106  via the display  104 . In such examples, the one or more of the executable controls  418  may be configured to modify at least one parameter of the exercise machine  102  that the user  106  is utilizing to participate in the exercise class based at least in part on such an input. 
     At  906 , the processor of the digital hardware  148  may receive user data collected while the executable control  418  is displayed via the display  104 . Such user data may include, for example, one or more sensor signals, control settings, speed settings, incline settings, resistance settings, cadence settings, and/or other settings of the exercise machine  102  selected by the user  106  during playback of the video file. For example, the processor of the digital hardware  148  may display the executable control  418  during a particular part of the video file received at  902 . In such examples, the user data received at  906  may comprise one or more settings (e.g., a first setting) of the exercise machine  102  selected by the user  106  during playback of the particular part of the video file to which the executable control  418  corresponds. In some examples, the first setting of the exercise machine  102  may comprise a current speed of the belt  120 , a current incline of the deck  112 , a current resistance associated with the belt  120 , a current braking resistance, pedal cadence, seat position, and/or other operating parameter of the exercise machine  102 , a current power zone of the user  106 , and/or any other performance metric. In other examples, the first setting may comprise a setting of the exercise machine  102  selected by the user  106  via one or more controls of the exercise machine  102  separate from the executable control  418  and during display of the executable control  418 . In still further examples, the first setting may comprise a setting of the exercise machine  102  that the user  106  selects by providing a touch input via the executable control  418  itself. In such examples, the displayed executable control  418  may be configured to receive a touch input from the user  106 , and to modify a parameter of the exercise machine  102  based at least partly on such a touch input. 
     At  910 , the processor of the digital hardware  148  may determine a difference between the first setting included in the user data received at  906 , and a second setting associated with the executable control  418  included in the video file received at  902 . For example, as noted above executable controls  418  of the present disclosure may include one or more respective settings. In embodiments in which the executable control  418  is generated based on a relatively specific performance command uttered by the instructor, the server  302  may configure the executable control  418  such that, when the executable control  418  is processed and/or executed by the processor of the digital hardware  148 , the processor of the digital hardware  148  may cause a component of the exercise machine  102  (e.g., a motor of the deck  112  controlling the speed of the belt  120 ) to operate and/or perform an action specifically defined by the corresponding setting of the executable control  418 . For example, in embodiments in which an instructor utters the relatively specific command “run at a 6.0 minute mile pace,” the server  302  may generate a corresponding executable control  418  that includes instructions, metadata, and/or other information or components (e.g., settings) which, when executed by the processor of the digital hardware  148 , will cause the motor of the deck  112  controlling the speed of the belt  120  to drive the belt  120  to rotate at a belt speed corresponding to a 6.0 minute mile pace. Similar settings may be included in an executable control  418  directed to a particular power zone, a particular incline of the deck  112 , a particular pedal cadence, a particular stationary bicycle braking resistance, and/or any other parameter of the exercise machine  102 . 
     On the other hand, in embodiments in which the instructor utters a relatively vague or abstract command, the server  302  may configure the executable control  418  such that, when the executable control  418  is processed and/or executed by the processor of the digital hardware  148 , the processor of the digital hardware  148  may determine an appropriate (e.g., a best fit) response corresponding to the executable control  418  settings before causing one or more components of the exercise machine  102  to operate in a modified manner. For example, in embodiments in which an example relatively abstract instructor command comprises “jog for a few minutes,” the server  302  may generate an executable control  418  including settings which when executed by the processor of an exercise machine  102  may cause the belt  120  of such an exercise machine  102  to rotate at a 4.0 minute mile pace, and/or at any other relatively common jogging pace, and such a setting of the executable control  418  may comprise a default setting. Alternatively, in examples in which a user profile of the user  106  identifies a preferred jogging pace, and/or in which the database  304  includes stored user data or other information indicating previously selected, previously customized, and/or previously entered jogging speeds of the particular user  106 , a weight, height, age, gender, or other physical characteristics of the user  106 , and/or other such information, the server  302  may generate an executable control  418  configured to cause the belt  120  to rotate at a jogging pace that corresponds to such user-specific information. 
     In any of the examples described herein, at  908  the processor of the digital hardware  148  may determine a difference between a current setting of the exercise machine  102  and one or more settings of the executable control  418 . For example, in instances in which, upon viewing the executable control  418  displayed at  904 , the user  106  modifies the various settings of the exercise machine  102  to match the settings associated with the executable control  418 , the difference, determined at  908  may be approximately zero. In such examples, the user  106  may be operating the exercise machine  102 , in accordance with the settings of the executable control  418 . For instance, the user  106  may have provided a touch input via the displayed executable control  418 , and as a result, the processor of the digital hardware  148  may have modified the settings of the exercise machine  102  to match the settings of the executable control  418 . Alternatively, upon viewing the executable control displayed at  904 , the user  106  may have provided an input via one or more controls of the exercise machine  102 , separate from the executable control  418 , to modify the settings of the exercise machine  102  to match the settings of the executable control  418 . The processor of the digital hardware  148  may have modified the settings of the exercise machine  102 , based at least in part on such input. 
     In still further examples, on the other hand, the user  106  may wish to approximate the settings of the executable control  418 . For instance, the user  106  may wish to exceed the settings indicated by the executable control  418  (e.g., although the executable control  418  includes a “6.0 minute mile pace” setting, the user  106  wishes to run at a 5.0 minute mile pace). Alternatively, the user  106  may wish to exercise at a slightly reduced intensity level (e.g., although the executable control  418  includes a “6.0 minute mile pace” setting, the user  106  wishes to run at a 7.0 minute mile pace). In any of the examples described above, at  908  the processor of the digital hardware  148  may determine a difference between the setting of the exercise machine  102  and the corresponding setting of the executable control  418 . 
     At  910 , the processor of the digital hardware  148  may generate an accuracy metric based at least in part on the difference, determined at  908 . Such an accuracy metric may comprise, among other things, any number (e.g., a difference, an average, a mode, a median, etc.), parameter, or other indicator of how accurately or inaccurately the user  106  is following the settings of the executable control  418 . It is understood that in some examples, such settings of the executable control  418  may correspond to the performance command uttered by the instructor. Such an example accuracy metric (e.g., −3%) is shown in the window  420  illustrated in  FIG. 4 . Additionally or alternatively, such an accuracy metric may comprise one or more graphics, images, figures, colors, flashing schema, or other visual indicia to provide an indication of how accurately or inaccurately the user  106  is following the settings of the executable control  418 . In any of the examples described herein (e.g., in the examples described above with respect to at least  FIGS. 4-6 ), the accuracy metric generated at  910  may be displayed and/or otherwise provided via the display  104 . 
     At  912 , the processor of the digital hardware  148  may determine whether the accuracy metric generated at  910  is outside of a desired accuracy range. For example, at  912  the processor of the digital hardware  148  may compare the accuracy metric generated at  910  to a range of values, comprising such an accuracy range. In examples in which the determined accuracy metric (e.g., a determined accuracy value) is either above the upper bounds or below the lower bounds of such an accuracy range ( 912 —Yes), the processor of the digital hardware  148  may cause the display of and/or may otherwise provide a notification to the user  106  via the display  104 . Such an example notification may comprise an encouragement, helpful tips, guidance, and/or other information that may be useful to the user  106 , in order to achieve the settings corresponding to the displayed executable control  418 . As shown in  FIG. 4 , an example notification or other corresponding information (e.g., “C′mon, let&#39;s pick up the pace!”) may be provided at  914  via one or more windows  422  of a user interface  400 . At  914 , and based at least in part on determining that the accuracy metric generated at  910  is outside of the accuracy range, the processor of the digital hardware  148  may provide a notification to the user  106 , via a window  422 , associated with the setting of the executable control  418 . 
     Alternatively, if the determined accuracy metric (e.g., a determined accuracy value) is less than or equal to the upper bounds of the accuracy range, and is greater than or equal to the lower bounds of such an accuracy range ( 912 —No), at  916  the processor of the digital hardware  148  may provide the accuracy metric to the user  106  via the display  104 . For example, as shown in at least  FIG. 4 , such an accuracy metric may be provided via a window  420  and/or other portion of a user interface  400  configured to provide information to the user  106  during participation in an exercise class. In some examples, if the determined accuracy metric (e.g., a determined accuracy value) is less than or equal to the upper bounds of the accuracy range, and is greater than or equal to the lower bounds of such an accuracy range ( 912 —No), operation  914  may be omitted. 
     It is understood that in any of the examples described herein, providing the accuracy metric at  916  may include providing the accuracy metric generated at  910  to a processor (e.g., a processor of the server  302 ) remote from the exercise machine  102  via the content distribution network  306 . In such examples, and as illustrated by the example user interface  500  of  FIG. 5 , the processor of the digital hardware  148  may receive, from the remote processor (e.g., from the processor of the server  302 ), and based at least in part on providing the accuracy metric to the remote processor, information indicative of a plurality of additional accuracy metrics. In such examples, each metric of the plurality of additional accuracy metrics may be associated with a respective user participating in the exercise class. As described above, via the content distribution network  306 , a plurality of additional users  106  may utilize respective exercise machines  102 , at disparate locations, to participate in the exercise class substantially simultaneously or at dates/times that are convenient for the respective users  106 . In such examples, the processor of the digital hardware  148  may display and/or otherwise provide at least a portion of the received information, via the display  104 , while providing the content via the display  104  at  904 . For example, as shown in  FIG. 5  an example user interface  500  may include, among other things, a leaderboard  502 . Such a leaderboard  502  may provide information  504  indicating the ranking of one or more of the users participating (currently or previously) in the present exercise class. Such a ranking may be, for example, a numerical ranking (e.g., 1-6,936 users, as indicated in the example leaderboard  502  of  FIG. 5 ) indicating the position, ranking, or rating of one or more of the users. Such ranking may be based on output, pace, speed, accuracy, or any of the other performance metrics described herein. For instance, the leaderboard  502  may include information  508  indicating the accuracy with which each of the listed users are following the current instruction provided by the instructor. 
     It is also understood that in any of the examples described herein, providing the accuracy metric at  916  may include displaying a user interface that includes a plot line indicative of the accuracy metric over time. For example, as illustrated in  FIG. 6 , an example user interface  600  may include, among other things, a workout summary window  606  providing a plurality workout information  608 . In such examples, such workout information  608  may include one or more workout summary, graphics  610 ,  612 ,  614 . As described above, such workout summary graphics  610 ,  612 ,  614  may each include a respective plot line  616   a ,  616   b ,  616   b . Such plot lines  616   a ,  616   b ,  616   b  may be illustrative of performance metrics associated with a particular user  106 , and recorded during participation of the user  106 , in an exercise class. For example, the plot line  616   a  may be indicative of changes in the output of the user  106  over the duration of a particular exercise class, the plot line  616   b  may be indicative of changes in the speed at which the user  106  jogged or ran over the duration of the exercise class, and the plot line  616   c  may be indicative of changes in the accuracy metric described above over the duration of the exercise class. In such examples, providing the accuracy metric may also include displaying a user interface  600  that includes a timeline, such as the segmented timeline  402  shown in  FIG. 6 , identifying one or more segments of the exercise class. As noted above with respect to  FIG. 6 , in such examples, the segmented timeline  402  may be displayed in association with the respective workout summary graphics  610 ,  612 ,  614  such that activities/segments of the workout corresponding to respective portions of, for example, the plot lines  616   a ,  616   b ,  616   b  can be easily identified by the user  106  via the user interface  600 . 
       FIG. 10  illustrates a flow chart depicting still another example method  1000  of the present disclosure. Similar to the method  800 , the example method  1000  is illustrated as a collection of steps in a logical flow diagram, which represents operations that can be implemented in hardware, software, or a combination thereof. In the context of software, the steps represent computer-executable instructions stored in memory. When such instructions are executed by, for example, the processor of the digital hardware  148  and/or by one or more processors of the server  302  described above, such instructions may cause the processor of the digital hardware  148  and/or the one or more processors of the server  302  to perform the recited operations. Such computer-executable instructions may include routines, programs, objects, components, data structures, and the like that perform particular functions or implement particular abstract data types. The order in which the operations are described is not intended to be construed as a limitation, and any number of the described steps can be combined in any order and/or in parallel to implement the process. For discussion purposes, and unless otherwise specified, the method  1000  is described with reference to the networked exercise system  300 , the one or more processors of the server  302 , one or more remote exercise machines  102  in communication with the server  302  via the content distribution network  306 , the user interfaces  200 ,  400 ,  500 ,  600 ,  700 , and/or other items shown in  FIGS. 1-7 . In particular, although any part of and/or the entire method  1000  may be performed by the processor of the digital hardware  148 , the method  1000  will be described below with respect to the one or more processors of the server  302 , and/or other components of the networked exercise system  300 , unless otherwise specified, for ease of description. 
     In example embodiments of the present disclosure, the example method  1000  of FIG.  10  may include, among other things, providing a first video file to a plurality of exercise machines  102 . For example, the method  1000  may include providing, with the one or more processors of the server  302 , a video file to a plurality of exercise machines  102  via the content distribution network  306 . In such examples, the video file may include audio content and video content of an instructor performing an exercise class. Further, it is understood that in some examples the video file may comprise a live stream of the instructor performing the exercise class in substantially real-time. In other examples, on the other hand, the video file may comprise a recording of the instructor performing the exercise class at a previous date/time. 
     At  1002 , the one or more processors of the server  302  may receive user data from the plurality of exercise machines  102 . For example, such user data may include respective settings (e.g., exercise machine settings) associated with one or more performance metrics. In some examples, the respective settings included in the user data received at  1002  may be associated with a common performance metric (e.g., an incline of the deck  112 , a speed of the belt  120 , a resistance of the belt  120 , pedal cadence, heart rate, pace, output, etc.). For example, respective settings (e.g., exercise machine settings) included in the user data received at  1002  may be settings utilized by users  106  of the plurality of exercise machines  102  during playback of a particular part of the first video file. For example, at a particular part of the first video file, the instructor may provide a performance command requesting that the users  106  participating in the exercise class run at a 6.0 minute mile pace. Based at least in part on hearing such a performance command, the users  106  participating in the exercise class may modify one or more settings of their respective exercise machines  102  in order to achieve (or attempt to achieve) the pace corresponding to the performance command. Similarly, one or more settings of the respective exercise machines  102  may be modified by the users  106  in order to achieve a resistance, an incline, a heart rate, a pedal cadence, and output, and/or any other performance metric corresponding to a performance command uttered by the instructor during the exercise class. The user data received by the one or more processors of the server  302  at  1002  may include respective settings associated with any such performance metrics. 
     As described above, example exercise machines  102  of the present disclosure may include one or more sensors  147  configured to sense, collect, measure, and/or otherwise determine performance metrics of the user  106 , settings of the exercise machine  102 , and/or other information. For example, one or more such sensors  147  may comprise a heart rate monitor, a proximity sensor, and/or other biometric sensor configured to sense, collect, measure, and/or otherwise determine a heart rate, a blood pressure, a body temperature, and/or other physical characteristics of the user  102  as the user participates in an exercise class using the exercise machine  102 . The exercise machine  102  may also include one or more additional sensors configured to sense, collect, measure, and/or otherwise determine a speed of the belt  120 , an incline of the deck  112 , a resistance of the belt  120 , a rotational speed of an output shaft of the motor utilized to drive the belt  120 , a position of an output shaft of the motor utilized to modify the incline of the deck  112  relative to the support surface on which the exercise machine  102  is disposed, a pedal cadence of a stationary bicycle, a braking force or resistance of the stationary bicycle, and/or other settings of the exercise machine  102 . In such examples, the one or more sensors  147  may include, among other things, a proximity sensor, an accelerometer, a gyroscope, and/or other sensors configured to determine speed, motion, position, and/or other parameters or settings. In any of the examples described herein, at  1002  one or more such sensors  147  may provide signals (e.g., continuously, substantially continuously, and/or at regular intervals) to the one or more processors of the server  302 , via the content distribution network  306 , including such user data. 
     At  1004 , the one or more processors of the server  302  may determine whether the user data received at  1002  comprises greater than a first minimum amount of user data required to generate an executable control  418  of the present disclosure. For example, in order to determine, with a relatively high degree of confidence, one or more settings of an executable control  418  being generated by the one or more processors of the server  302 , the one or more processors of the server  302  may determine whether a minimum amount of user data has been received. For instance, in embodiments in which user data associated with only a single user  106  (e.g., a minimum amount equal to two users  106  or two exercise machines  102 ) has been received at  1002 , the one or more processors of the server  302  may determine that the amount of user data received at  1002  is less than the minimum required amount ( 1004 —No). In such embodiments, the one or more processors of the server  302  would proceed to step  1002 . On the other hand, in embodiments in which user data associated with three or more users  106  (e.g., a minimum amount equal to two users or two exercise machines  102 ) has been received at  1002 , the one or more processors of the server  302  may determine that greater than a minimum required amount of user data (e.g., first user data associated with a first user  106 , combined with second user data associated with a second user  106 , and combined with third user data associated with a third user  106 ) has been received at  1002  ( 1004 —Yes). In such embodiments, the one or more processors of the server  302  would proceed to step  1006 . 
     At  1006 , the one or more processors of the server  302  may determine whether the user data received at  1002  is characterized by, is indicative of, and/or otherwise corresponds to one or more metrics above a required threshold. For example, even in embodiments in which greater than a minimum amount of user data has been received at  1002  ( 1004 —Yes), such user data may or may not be sufficient to determine one or more settings of an executable control  418  and/or otherwise sufficient to generate such an executable control  418 . For instance, one or more minimum percentage thresholds, minimum length of time thresholds, frequency ranges, minimum and/or maximum parameter values, and/or other metrics may be established and/or otherwise utilized in the process of generating an executable control  418 . In any of the examples described herein, at  1006  the one or more processors of the server  302  may compare the user data received at  1002  with one or more such thresholds and/or other metrics in order to determine whether the received user data satisfies such thresholds and/or other metrics. 
     For example, in one embodiment, one or more such thresholds and/or other metrics may comprise a second minimum percentage (e.g., 50% of all users  106 , 60% of all users  106 , 70% of all users  106 , etc.) or amount (e.g., 100 users, 200 users, 300 users, etc.) of user data that is determined to be indicative of a common performance metric across the plurality of exercise machines  102  used to participate in the exercise class. In such an example embodiment, if greater than a second minimum amount of users  106  (e.g., 50% of all users  106 ; 100 users, etc.) utilized a common belt speed (e.g., a speed corresponding to a 6.0 minute mile pace) during playback of a particular part of the first video file at which the instructor provided a performance command ( 1006 —Yes), the one or more processors of the server  302  would proceed to step  1008 . Alternatively, if less than or equal to such a second minimum amount of users  106  (e.g., 40% of all users  106 ; 90 users, etc.) utilized a common belt speed (e.g., a speed corresponding to a 6.0 minute mile pace) during playback of a particular part of the first video file at which the instructor provided a performance command ( 1006 —No), the one or more processors of the server  302  would proceed to step  1002 . 
     At  1008 , the one or more processors of the server  302  may generate one or more executable controls  148  for a user interface  400 ,  500  based at least in part on the user data received at  1002 . In such examples, the one or more executable controls  148  generated at  1008  may correspond to the common performance metric associated with the respective settings included in the user data received at  1002 . Further, in some examples, one or more executable controls  418  generated at  1008  may be operable to modify a parameter of an exercise machine  102  being utilized by a user  106  to participate in the exercise class. In other examples, on the other hand, one or more executable controls  418  generated at  1008  may comprise a message or information provided by the instructor and may not be configured to receive an input from users  106 . 
     As noted above, one or more executable controls  418  may comprise data files, text files, digital files, metadata, instructions, and/or any other electronic file executable by the processor of the digital hardware  148 . When an example executable control  418  generated at  1008  is executed by the processor of the digital hardware  148 , the processor may cause display of the text or other information associated with the executable control  418  via a user interface (e.g., user interface  400 ). In some examples, such text (e.g., guidance, an encouraging statement, etc.) may be displayed via one or more respective windows  422  included in the user interface  400 . In some examples, such windows  422 , executable controls  418 , and/or other portions of the example user interfaces  400  described herein may be provided to the user  106  during an exercise class as a means of communicating with, guiding, and/or encouraging the user  106 . In some examples, such windows  422  and/or executable controls  418  may not be configured to receive user input and may not be operable to modify on or more parameters of the exercise machine  102 . In additional examples, on the other hand, one or more of the executable controls  418  described herein may be configured to receive a touch input from the user  106  via the display  104 . In such examples, the one or more of the executable controls  418  may be configured to modify at least one parameter of an exercise machine  102  that a user  106  is utilizing to participate in the exercise class based at least in part on such an input. In example embodiments of the present disclosure, one or more of the executable controls  418  generated at  1008  may comprise one or more settings associated with modifying a parameter of the exercise machine  102 . 
     For example, at  1008  the one or more processors of the server  302  may identify a timestamp associated with the particular part of the video file at which the respective settings associated with the common performance metric described above are used. At  1008 , the one or more processors of the server  302  may also generate the executable control  418  corresponding to the performance metric. In particular, at  1008  the one or more processors of the server  302  may configure the executable control  418  such that, when the executable control  418  is processed and/or executed by the processor of the digital hardware  148  (e.g., of an exercise machine  102 ), the processor of the digital hardware  148  may cause a component of the exercise machine  102  (e.g., a motor of the deck  112  controlling the speed of the belt  120 ) to operate and/or perform an action specifically defined by the executable control  418 . For example, in embodiments in which the respective settings associated with the common performance metric described above correspond to rotating the belt  120  at a 6.0 minute mile pace, at  1008  the one or more processors of the server  302  may generate a corresponding executable control  418  that includes instructions, metadata, and/or other information or components which, when executed by the processor of the digital hardware  148 , will cause the motor of the deck  112  controlling the speed of the belt  120  to drive the belt  120  to rotate at a belt speed corresponding to a 6.0 minute mile pace. 
     At  1010 , the one or more processors of the server  302  may generate a video file (e.g., a second video file) comprising the audio content, the video content, and/or any other content of the first video file described above. For example, such a second video file may comprise audio content and video content of the exercise class performed by the instructor. 
     At  1012 , the one or more processors of the server  302  may embed, link, and/or otherwise associate the executable control  418  (generated at  1008 ) with the second video file (generated at  1010 ) such that playback of at least part of the second video file by the processor of the digital hardware  148  via the display  104  may result in display of the executable control  418 . In particular, at  1012  the one or more processors of the server  302  may link the executable control  418  to the particular part of the second video file corresponding to the timestamp described above (e.g., the particular part of the second video file at which the instructor utters the performance command corresponding to the executable control  418 ). In such examples, the timestamp may comprise an elapsed time of the second video file generated at  1010 . As a result, when providing the exercise class to the user  106  via a user interface  400 ,  500  (e.g., either in substantially real time via live streaming, and/or upon playback of the exercise class using an archived video file), the processor of the digital hardware  148  may provide the executable control  418  at the point in time during the exercise class in which the instructor uttered the verbal command. In particular, playback of the second video file may cause display of the executable control  148  at a part of the second video file corresponding to the timestamp. Further, it is understood that in some examples, the processes described herein with respect to step  1012  may be performed during step  1010 . In such examples, step  1012  may be omitted. 
     At  1014 , the one or more processors of the server  302  may provide the executable control  418 , together with the second video file generated at  1010 , to one or more exercise machines  102  via the content distribution network  306 . In such examples, the video packetizer  326  of the server  302  may provide one or more signals to a plurality of exercise machines  102  via the network  306 , and such signals may include, at least part of the second video file and/or the executable control  418  embedded therein. In some examples, such as an example in which a user  106  is live streaming the exercise class in substantially real-time, the server  302  may provide the second video file generated at  1010  and the executable control  418  generated at  1008 , via the network  306 , as part of a live stream of the exercise class. Alternatively, in examples in which the user  106  is participating in an archived exercise class, at  1014 , the server  302  may provide the second video file generated at  1010  and the executable control  418  generated at  1008 , via the network  306 , as part of a transmission of the archived exercise class. 
     In any of the examples described herein, user data may be received, at  1002 , from a first plurality of exercise machines  102  used by a first plurality of users  106  to participate in the exercise class. In such examples, the first video file described above may be displayed to the first plurality of users  106  via respective displays  104  of the first plurality of exercise machines  102 . Accordingly, the user data received at  1002  may be user data corresponding to the first plurality of users  106 . Thus, at  1014  the one or more processors of the server  302  may provide the second video file (generated at  1010 ) to a second plurality of exercise machines  102  separate from the first plurality of exercise machines  102 . The second plurality of exercise machines  102  may be used by a second plurality of users  106  to participate in the exercise class associated with the second video file generated at  1010 . In such examples, the second video file may be displayed to the second plurality of users  106  via respective displays  104  of the second plurality of exercise machines  102 . Accordingly, in embodiments of the method  1000 , the one or more processors of the server  302  may receive additional user data corresponding to the second plurality of users  106 . The receipt of such additional user data may be similar to the processes described above with respect to step  1002 . 
     Further, at  1016 , the server  302  may save and/or otherwise store the executable control  418  generated at  1008  together with the second video file generated at  1010 . In such examples, the executable control  418  may be linked to, embedded within, associated with, and/or otherwise stored with the second video file such that, upon playback of the second video file, the executable control  418  may be displayed as part of a user interface  400 ,  500  presented to the user  106  via the display  104 . Further, while the previous disclosure indicates that the one or more processors of the server  302  may perform one or more operations of the method  1000 , in any of the examples described herein, any of the operations described above with respect to the method  1000  may be performed, in whole or in part, by the server  302 , an operator of the server  302 , an operator of a control station at which an exercise class is being performed by an instructor, and/or by any combination thereof. 
     In still further embodiments, any of the methods (e.g., the methods  800 ,  900 ,  1000 ) described herein may be utilized to generate a content file that does not include video content. Such a content file may then be used (instead of the video files described herein with respect to the methods  800 ,  900 ,  1000 ) for one or more of the remaining steps in such methods. 
     For instance, and by way of example, in some embodiments of the method  800  described above with respect to  FIG. 8 , at  802  the server  302  and/or other components of the networked exercise system  300  may capture content associated with an exercise class being performed by an instructor, and in such examples, one or more video cameras  308 , microphones  310 , music players  312 , audio mixers  314 , and/or other components of the networked exercise system  300  may be utilized by and/or in conjunction with the server  302  to sense, record, and/or otherwise capture the exercise class content at  802 . For example, at  802  the server  302  may capture at least audio content corresponding to the exercise class being performed by the instructor. In such examples, at  804 , the server  302  may generate a content file comprising the audio content captured at  802 . For example, audio content may be captured at  802  in an audio track, and the content file generated at  804  may comprise the audio track without a corresponding video track. In such examples, while video content may also be captured at  802 , such video content may not be incorporated into the content file at  804 . 
     In such example embodiments, at  806  the server  302  may identifying a performance command included in the audio content, and the performance command may comprise a command uttered by the instructor during the exercise class. At  806 , the server  302  may also identify a timestamp associated with the performance command. In such examples, at  808  the server  302  may generate an executable control corresponding to the performance command as described above, and at  810  the server  302  may associated the executable control with the content file generated at  804 . In doing so, at  810  the server  302  may generate an augmented or otherwise modified content file comprising the audio content and the executable control. As noted above, such an augmented or otherwise modified content file may not include video content. Additionally, playback of such a content file may cause display of the executable control and/or output of audio corresponding to the executable control at a part of the content file (e.g., at a part of the audio track) corresponding to the timestamp. At  812 , the server  302  may provide the content file to an exercise machine, via a network, based at least in part on a request received via the network. Further, at  814  the server  302  may store the content file. 
     In any of the examples described herein, such a content file (e.g., a content file that does not include video content) may be utilized in place of the various video files described above. For instance, in some embodiments of the example method  900 , such a content file may be received at  902 , and the content included in the content file may be provided at  904 . Similarly, in some embodiments of the example method  1000 , such a content file may be generated by the server  302  at  1010  instead of one or more of the video files described above. In such examples, the server  302  may generate an augmented content file at  1012  by, among other things, associating an executable control with the content file. The server  302  may provide the content file at  1014 , and may store the content file at  1016 .
