CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of U.S. patent application Ser. No. 17/080,385, filed Oct. 26, 2020, which is a continuation of U.S. patent application Ser. No. 16/023,762, filed Jun. 29, 2018, which claims the benefit of and priority to both of U.S. Provisional Patent Application 62/527,869, filed Jun. 30, 2017, and U.S. Provisional Patent Application 62/622,490 filed Jan. 26, 2018, all of which are incorporated herein by reference in their entireties. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to treadmills. More particularly, the present disclosure relates to a lighting system for treadmills and other exercise equipment. 
     BACKGROUND 
     Treadmills enable a person to walk, jog, or run for a relatively long distance in a limited space. Treadmills can be used for physical fitness, athlete training and therapeutic uses for the treatment of medical conditions. It should be noted that throughout this document, the term “run” and variations thereof (e.g., running, etc.) in any context is intended to include all substantially linear locomotion by a person. Examples of this linear locomotion include, but are not limited to, jogging, walking, skipping, scampering, sprinting, dashing, hopping, galloping, lane slides, side stepping, shuffling, etc. The bulk of the discussion herein is focused on training and physical fitness, but persons skilled in the art will understand that all of the structures and methods described herein are equally applicable in medical therapeutic applications. 
     A person running generates force to propel themselves in a desired direction. To simplify this discussion, the desired direction will be designated as the forward direction. As the person&#39;s feet contact the ground (or other surface), their muscles contract and extend to apply a force to the ground that is directed generally rearward (i.e., has a vector direction substantially opposite the direction they desire to move). Keeping with Newton&#39;s third law of motion, the ground resists this rearwardly directed force from the person, resulting in the person moving forward relative to the ground at a speed related to the force they are creating. While the prior discussion relates solely to movement in the forward direction, persons skilled in the art will understand that this can mean movement in any direction, for example side to side, backward/reverse, or any desired direction. 
     To counteract the force created by the treadmill user so that the user stays in a relatively static fore and aft position on the treadmill, a running belt of a treadmill is driven or rotated (e.g., by a motor). Thus, in operation, the running belt moves at substantially the same speed as the user, but in the opposite direction. In this way, the user remains in substantially the same relative position along the treadmill while running. 
     SUMMARY 
     One implementation of the present disclosure is a treadmill. The treadmill includes a frame. The frame includes a first side member, a second side member, and a cross-member coupled to and extending between the first side member and the second side member. The treadmill also includes a belt coupled to the frame and configured to rotate about the cross-member. The treadmill also includes a light source coupled to the first side member, the second side member, and the cross-member and a controller configured to control the light source. 
     Another implementation of the present disclosure is a method. The method includes providing a light source with a treadmill and operating the light source to illuminate the treadmill. The method also includes receiving data regarding a parameter relating to a use of the treadmill by a user and controlling the color or brightness of light emitted by the light source based on the data. 
     Another implementation of the present disclosure is a treadmill. The treadmill includes a frame, a running belt coupled to the frame, a handrail coupled to the frame, a console coupled to the handrails, and a sensor coupled to the frame, the handrails, or the console. The sensor is configured to detect a position of a user relative to a longitudinal center line of the running belt. The treadmill also includes a plurality of light sources distributed horizontally across the console and operable to indicate the position of the user relative to the center line of the running belt. 
     This summary is illustrative only and is not intended to be in any way limiting. Other aspects, inventive features, and advantages of the devices or processes described herein will become apparent in the detailed description set forth herein, taken in conjunction with the accompanying figures, wherein like reference numerals refer to like elements.

     DETAILED DESCRIPTION 
     Before turning to the Figures, which illustrate the exemplary embodiments in detail, it should be understood that the application is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology is for the purpose of description only and should not be regarded as limiting. 
     Referring to the Figures generally, a lighting system is disclosed according to various embodiments herein. In particular, a lighting system for a treadmill is disclosed according to various embodiments herein. In some uses of the treadmill, users prefer the treadmill to be situated in a dark or near dark environment. Therefore, Applicant has determined that a lighting system for the treadmill may be beneficial to increase visibility of the treadmill among other benefits. Particularly, Applicant has determined that the lighting system may provide dynamic and coordinated lighting routines (e.g., programs that vary one or more light sources&#39; colors, brightness, transitions between colors and light sources, etc.), which provide useful and beneficial cues to the user of the treadmill (e.g., indicate their running speed, their positioning on the treadmill, and the like). According to the present disclosure, the lighting system includes a light that shines or illuminates a belt of the treadmill. In addition, lighting can also be included or disposed along a base of the treadmill, at or near a back or rear portion of the treadmill, within a base of the treadmill, along handrails of the treadmill, on or near the display of the display device, inside cup holders or other compartments of the display or console, as a metered light positioned substantially transverse to the longitudinal axis of the running belt, and/or along, within, or at various other portions of the treadmill. The lighting system may provide ambient lighting, dynamic lighting, or other customizable lighting. Therefore, Applicant has determined a lighting system on the treadmill may provide enhanced benefits relative to conventional treadmills especially when such treadmills are used in a dark or near dark environment. It should be understood that while the lighting system disclosed herein is described in relation to a treadmill, the present disclosure contemplates other applications of the lighting system with all such variations intended to fall within the spirit and scope of the present disclosure (e.g., a stationary bike, a skiing machine, a rowing machine, etc.). 
     Referring now to  FIGS.  1 - 4   , various views of a treadmill  100  with various lighting systems  150  are shown, according to an exemplary embodiment. The treadmill  100  includes a base  102 , handrails  106  mounted or coupled to the base  102 , a display device or console  200  coupled to the handrails  106 , a running belt  104  that extends substantially longitudinally along a center of the base  102 , and the lighting system  150 . The base  102  generally refers to the lower portion of the treadmill  100  (i.e., all components of the treadmill  100  excluding the handrails and generally features positioned vertically above the base  102 , such as the console  200 ). As shown, the base  102  may be elevated off a support surface for the treadmill  100  via legs  112  (e.g., support feet, etc.) coupled to the base  102 . 
     In the example shown, the treadmill  100  receives power from a wall outlet (e.g., 120 VAC in the U.S., 230 VAC in other countries, etc.). The electrical connection is not depicted in  FIGS.  1 - 4   . In other embodiments, the treadmill  100  is powered by an on-board power source, such as one or more batteries. In still other embodiments, the treadmill  100  may include a power source, but also receive power from a remote location, such as an outlet. In an alternate embodiment, a generator may be included with the treadmill  100  that generates electricity to provide power to the lighting system  150  when a user operates the treadmill  100 . All such variations and combinations thereof are intended to fall within the spirit and scope of the present disclosure. 
     In the example shown, the treadmill  100  includes a planar (e.g., a flat or substantially flat) running surface for the running belt  104  (i.e., the part of the running belt  104  that a user utilizes or engages with when using the treadmill  100 ). In other embodiments, the treadmill  100  includes a non-planar running surface. For example, the treadmill  100  may include a running belt  104  that defines a curved running surface upon which a user may run. In the example shown, the treadmill is motorized such that the running belt  104  is powered by a motor (not shown), which selectively drives, powers, moves, or otherwise rotates the running belt  104  at various desired running belt speeds. In other embodiments, the running belt  104  may be manually powered (i.e., no motor) such that a force applied by the user to the running belt  104  causes rotation or movement of the running belt  104 . In these configurations, power for the lighting system  150  may be provided by a wall outlet, an electrical storage device on the treadmill (e.g., a battery), and/or some combination thereof. 
     In this embodiment, the lighting system  150  includes any combination of one or more different light sources, including a belt light source  108 , under light source  114 , tail light source  116 , metered light sources  214 , and cup holder light source  216 . Each of these are described in more detail below. The first light source to be described is the belt light source  108 , which is coupled to the console  200 . In operation, the belt light source  108  creates, generates, emits, or otherwise provides a light beam  110  to illuminate the running belt  104 . Beneficially, the belt light source  108  provides lighting to aid a user in seeing or observing the running belt  104  while operating the treadmill  100  as well as a position of their legs and feet on or near the belt  104 . 
     The second light sources to be described are the underside light sources  114 , which are coupled to an underside of the base  102 . The underside of the base  102  includes under light sources  114  that extend substantially longitudinally along the underside of the base  102 . Coupling of the under light sources  114  to the base  102  may be via any typical means (e.g., screws or other fasteners, adhesive, combination of adhesive and fasteners, etc.). The under light sources  114  provide ambient lighting to illuminate an area associated with the underside of the base  102  (i.e., around the base  102 ; between the base  102  and a ground or support surface for the treadmill  100 ). As shown, a rear of the base  102  may include other light sources, specifically tail light sources  116  that provide illumination outward and at least partly away from the rear of the base  102  (the “rear” or “back” refers to an area away from the display device, which is associated with the “front”). The tail light sources  116  provide a visualization of a rotation of the running belt  104 . Such tail light sources  116  may also be an indicator to the user and others nearby of a “rear end” of the treadmill (i.e., where the physical structure of the treadmill  100  ends or stops). In combination with the under light sources  114 , this set of light sources  114  and  116  may provide an indication to the user and to others of the occupied space or area of the treadmill  100  on a support surface. Such illumination may be beneficial to prevent or substantially prevent others from accidentally walking into the treadmill  100  when the others are in a dark or near dark environment. 
     In some embodiments, the treadmill  100  includes light sources along the side of the belt  104 . For example, the treadmill  100  may include track light sources coupled to the base  102  along a top portion of the base  102  and proximate the belt  104  (i.e., longitudinally along each side of the belt  104 ). For example, the treadmill  100  may include a first track of light sources along a first side of the belt  104  and a second track of light sources along a second side of the belt  104 . The track light sources may thereby illuminate the edges of the belt and make it easier for a user to center themselves on the running belt  104  as well as providing additional ambient lighting of the treadmill  100 . In some embodiments, the treadmill  100  may include light sources (not shown) extending along or substantially along a length of the handrails  106 . The handrail light sources may aid in helping the user find the handrails  106  during use of the treadmill  100  as well as providing additional ambient lighting for the treadmill  100 . 
     Referring now to  FIGS.  5 - 6   , close up views of the console  200  of the treadmill  100  of  FIGS.  1 - 4    are shown, according to an exemplary embodiment. As shown, the display device or console  200  includes a display base  202  mounted to or coupled to the handrails  106 , and a display screen  204  mounted to or coupled to the display base  202 . The console  200  may include an integrated power source (e.g., a battery), or be electrically coupleable to an external power source (e.g., via an electrical cord that may be plugged into a wall outlet). The console  200  may include any type of display device including, but not limited to, touchscreen display devices, physical input devices in combination with a touch screen, physical input devices in combination with a display, and so on. 
     In the example shown, the display base  202  includes additional handrails  206 . In other embodiments, such handrails  206  may be excluded from the console  200 . The handrails  206  are shown to include sensors  208  which are configured to collect body parameter information or data from a user when, e.g., their hands are placed on or otherwise engage with the sensors  208 . The body parameters may include, but are not limited to, heart rate, calorie count, SpO 2 , CO 2 , O 2 , etc. Thus, the sensors  208  may have any structural configuration adapted to acquire such data. 
     Various sensors  208  may be included with the treadmill  100  and structured to acquire data regarding the use of the treadmill  100  by a user and/or data which can be collected, or calculated, using the sensors  208 . The acquired information may be displayed via the display screen  204 . The data may also include workouts preprogrammed into the treadmill  100 . This data may be used as an input for the lighting system  150 . 
     The display base  202  also includes cup holders  210  and, in some embodiments, may further include other compartments. The cup holders  210  and/or other compartments allow a user to store beverage containers (e.g., cups, bottles, cans, etc.), electronics (e.g., mobile phones, music players, television remotes, etc.), keys, cards (e.g., personal identification, club membership cards, etc.), or various other items. In the embodiment shown, a pair of cup holders  210  are positioned symmetrically across a center line of the treadmill. The cup holders  210  may be formed as substantially cylindrical recesses in the display base  202 . As shown, the cup holders  210  may be coupled to the console  200  and/or the handrails  106 . 
     In this configuration and as mentioned above, the lighting system  150  includes a light source disposed in the cup holder  210 , for example a cup holder light source  216  operable to project light into, onto, and/or out of the cup holder  210 . In the embodiment shown, the cup holder light source  216  is coupled to a first side wall  215  of the cup holder  210  and oriented to project light onto an opposing side wall  211  of the cup holder  210 . The light may reflect off the opposing side wall  211  and/or a bottle, cup, etc. placed in the cup holder  210  to illuminate the cup holder  210 . In other embodiments, the cup holder light source  216  may be disposed near or proximate to the cup holder  210 , for example around an outside edge of the cup holder  210 . The cup holder light source  216  thereby aids the user in placing items into the cup holders  210  by illuminating the cup holders  210 . In embodiments where a pair cup holders  210  are positioned symmetrically across the center line of treadmill, the light from the cup holder light sources at each cup holder  210  may facilitate the user in positioning him or herself centrally on the running belt in a substantially dark environment. 
     The display screen  204  is adapted or configured to display various information to a user (e.g., speed of the running belt, exercise routine (e.g., 5 KM run), heart rate or other user health data, time elapsed, time remaining, calories burned, distance traveled, and so on). As shown, the display screen  204  is a touchscreen display with a backlight. In some embodiments, the display screen  204  provides visual options for a user to select via buttons (not shown). As also shown, the console  200  includes light sources that illuminate the display screen  204 , for example display lights  212 , which are also configured to illuminate buttons of the console  200  when such buttons are included with the console  200 . In some embodiments, display light sources  212  illuminate both the display screen  204  and the console  200 . As further shown, the console  200  or the display screen  204  includes metered light sources  214  coupled to the console and positioned horizontally across the console. The metered light sources  214  include multiple light sources that form a series of bars that can be individually lit to provide additional information to a user. 
     Referring now to  FIG.  7   , a block diagram of the lighting system  150  of  FIGS.  1 - 4    is shown, according to an exemplary embodiment. The lighting system  150  includes inputs  302 , a microcontroller  316 , and outputs  318 . The inputs  302  represent parameters and ways to receive parameters of the lighting system  150 . In this regard and as shown, the ways to receive parameters are shown to be any of a combination of wireless and wired transmission technologies (i.e., the parameters could be received via only wired technology, only wireless technology, or via a combination of wired and wireless technologies). In the example depicted, control parameters for the lighting system  150  may be received via both wired and wireless technologies. In this regard, ways to receive various control parameters for the lighting system  150  include a wireless transmission technology, which is shown as a BLUETOOTH connection  310 , and various wired/direct communication technologies, which are shown as a USB connection  312  and buttons  314 . It should be understood that any type and combination of wired (e.g., cables, etc.) and/or wireless communication technologies (e.g., Internet, near-field communication transmission, radio technology, etc.) may be used to supply the control parameters to the microcontroller  316 . In this regard, remote control technologies (e.g., a remote controller disposed away/separate from treadmill  100 ) may be coupled to the microcontroller  316 , which would enable remote control of the lighting system  150 . Further, other input devices included with the treadmill  100  other than, or in addition to, the buttons  314  may be used to define one or more control parameters. The parameters of the inputs  302  are described in more detail below. The inputs  302  may be used by the microcontroller  316  to control operation of the outputs  318 , which represent the light sources  320 . In other words, the inputs  302  may dictate how the lighting system  150  operates. In some embodiments, a default program may be utilized by the microcontroller  316  to control operation of the lighting system  150 . 
     The microcontroller  316  is a controller or control system for the lighting system  150 . While shown as only one component, the microcontroller  316  may include two or more sub-controllers. Further, in some embodiments, the microcontroller  316  may be included with a controller or control system for the treadmill  100  overall. The microcontroller  316  may have a variety of configurations. In the example shown, the microcontroller  316  represents a computer on a single integrated circuit (i.e., a system on a chip). The microcontroller  316  may include one or more processing components (e.g., a processor such as that described below) coupled to one or more memory devices (example structures described below). Additionally, the microcontroller  316  may include one or more communications interfaces (e.g., BLUETOOTH, USB, internet, etc.) for communicably coupling the microcontroller  316  to one or more components. The one or more processing components may be implemented as one or more general-purpose processors, an application specific integrated circuit (ASIC), one or more field programmable gate arrays (FPGAs), a digital signal processor (DSP), a group of processing components, or other suitable electronic processing components. In some embodiments, the one or more processors may be shared by multiple circuits. Alternatively or additionally, the one or more processors may be structured to perform or otherwise execute certain operations independent of one or more co-processors. In other example embodiments, two or more processors may be coupled via a bus to enable independent, parallel, pipelined, or multi-threaded instruction execution. All such variations are intended to fall within the scope of the present disclosure. The one or more memory devices (e.g., RAM, ROM, Flash Memory, hard disk storage, etc.) may store data and/or computer code for facilitating the various processes described herein. The one or more memory devices may be communicably connected to the one or more processors to provide computer code or instructions to the one or more processors for executing at least some of the processes described herein. Moreover, the one or more memory devices may be or include tangible, non-transient volatile memory or non-volatile memory. Accordingly, the memory devices may include any type of information structure for supporting the various activities and information structures described herein. 
     As shown, the parameters depicted in the inputs  302  include a preference for a dynamic (i.e., changing) or static (unchanging) control of color from the light sources  320 , brightness of the light sources  320  or of a subset of the light sources  320 , and transitions  304  of light sources  320  on the treadmill  100  (i.e., how the light sources  320  transition between and among each other, how the colors transition, how brightness transitions, how light sources  320  flash, blink, etc. and the like), which as mentioned above may be received via a USB  312  or BLUETOOTH  310  communication. It should be understood that this configuration is not meant to be limiting as other inputs are also contemplated by the present disclosure (e.g., which light sources are activated/on and when, flashing, blinking etc.). Alternatively, or in addition to the dynamic control of color, brightness, and transitions  304 , buttons  314  may be used to receive color  306  and brightness  308  control from the user. The dynamic control of color, brightness, and transitions  304  may also include data collected from the treadmill  100  (e.g., sensors  208 , running belt  104 , etc.). 
     As mentioned above, the outputs  318  represent how the microcontroller  316  (also referred to herein as a controller) controls the lighting system  150  (i.e., how the lighting system  150  and, particularly, light sources  320  are operated based on one or more inputs  302 ). The light sources  320  refer to the various light sources of the lighting system  150  described above. In this regard, the light sources  320  include the belt light source  108 , under light sources  114 , track light sources, tail light sources  116 , handrail light sources, cup holder light sources  216 , and metered light sources  214 . In one embodiment, the light sources  320  are LED light sources (e.g., RGB LEDs, RGBW LEDs, etc.). In another embodiment, the light sources  320  may be any type of light source (e.g., fluorescent, halogen, incandescent, etc.). In still another embodiment, the light sources  320  are a combination of LEDs and another type of light source. All such structural configurations for the light sources  320  themselves are contemplated to fall within the present disclosure. 
     The data collected from the treadmill  100  may include stride length. In one embodiment, stride length may be determined using a repeater wheel on the treadmill. The repeater wheel acquires/determines impulses in speed collected from impact of a foot of a user, which causes an impulse in speed. A time between impulses is determined, and a distance traveled by the running belt  104  can then also be subsequently determine using one or more algorithms or formulas. 
     The data collected may also include stride force (e.g., acquired by sensors, such as load cells disposed proximate the running belt  104 ), heart rate, cadence, pace, distance, resistance level, incline level, calorie count, time, carver counts, carver cadence, bounce, step count and/or proximity of the user from the left, right, front and/or back of the running belt  104 . 
     As described herein, the collected data may be used by the microcontroller  316  to control or manage the lighting system  150 . Particulars of the control scheme or routine may be defined in regard to one or more inputs  302  (e.g., a user may designate that speeds above a certain threshold should cause the belt light source  108  to illuminate yellow whereby the data collected includes speed data, which is then in turn utilized by the controller  316  to selectively cause the belt light source  108  to illuminate yellow). In one embodiment, a single data parameter is used for the dynamic control of color, brightness, and transitions  304 . In other embodiments, a combination of data is used for dynamic control of color, brightness, and transitions  304 . For example, different light sources  320  may be controlled, at least partially or indirectly, through specifically designated data (e.g., the belt light source  108  is controlled by data collected regarding the speed of the belt while the metered light sources  214  are controlled based on data collected indicative of a position of the user on the running belt, etc.). 
     The dynamic control of color, brightness, and transitions  304  includes parameter settings to control the light sources  320  based on the data collected. The dynamic control of color, brightness, and transitions  304  may cause color, brightness or a transition between color and brightness when a parameter of the data changes (e.g., transition from red to green when the user reaches a target heart rate range, increase in brightness as distance traveled increases, etc.). The dynamic control of color, brightness, and transitions  304  may be preset, or may be provided parameters to the user via the display screen  204  that can be modified by the user via buttons  314 . The user may be able to adjust the color, brightness and/or transitions as well as change parameters that cause the changes in color, brightness or transitions. As mentioned above, the transitions may include color transitions, which light source transitions to which light source (e.g., under light sources to tail light sources), brightness transitions, and/or a combination thereof. In some embodiments, color schemes may be associated with data, workout profiles, or selected by the user. In some embodiments, the user may be able to independently control light sources on a left side of the treadmill  100  and a right side of the treadmill  100 . In some embodiments, a change may be indicated by a flash of light. 
     In this regard, the data collected may be used to define ranges, thresholds or other parameters used by the microcontroller  316  to control the light sources  320 . For example, a target heart rate range can be set by the user or preprogrammed by the treadmill  100 . When the user is within the target heart rate range, the light sources  320  may illuminate a first color (e.g., green); when the user is below the target heart rate range, the light sources  320  may illuminate a second color (e.g., blue); and when the user is above the target heart rate range, the light sources  320  may illuminate a third color (e.g., red). The transitions between colors may include a fade of one color into the next, a substantially abrupt change from one color to the next, a mix of both colors during the transition, etc. or a combination thereof. In another example, the user may set a target distance (e.g., 3 miles). When the user is below a first distance threshold (e.g., less than 1 mile), the light sources  320  may illuminate at a first brightness (e.g., dim); when the user is below a second distance threshold (e.g., between 1 mile and 2 miles), the light sources  320  may illuminate at a second brightness (e.g., regular); when the user is below a third distance threshold (e.g., between 2 miles and 3 miles), the light sources  320  may illuminate at a third brightness (e.g., bright). The transitions between brightness may include a fade of one brightness into the next, a substantially abrupt change from one brightness to the next, etc. or a combination thereof. In some embodiments, both color and brightness can be used and a combination of transitions can be used. 
     In other words, the microcontroller  316  may set a threshold value of a parameter (e.g., a particular speed, distance, heartrate, cadence, etc.). The microcontroller  316  may receive data indicating the current value of that parameter, for example from a sensor that measures the parameter, and compare the current value to the threshold value. The microcontroller  316  may then control light sources  320  to emit light of a first color, brightness, pattern, etc. if the current value is less than the threshold value and a second color, brightness, pattern, etc. if the current value is greater than the threshold value. A desired range for a parameter may be defined using a first threshold (i.e., a minimum value) and a second threshold (i.e., a maximum value). The microcontroller  316  may control the light sources  320  to provide cues to a user or instructor regarding use of the treadmill  100 . 
     In some embodiments, the dynamic control of color, brightness, and transitions  304  includes dynamic control of the metered light sources  214 . The metered light sources  214  include multiple independent light sources (e.g., bars). Dynamic control of the metered light sources  214  may cause the individual light sources of the metered light sources  314  to individually illuminate. For example, the metered light sources  214  may include a number of individual light sources (e.g., 3, 4, 5, 7, etc.) that can be individually illuminated. The individual light sources of the metered light sources  214  can be individually illuminated based on user input, data, data parameters, etc. In some embodiments, a single light source of the metered light sources  214  may illuminate when a certain parameter is obtained (e.g., a distance, a time, an incline level, etc.). For example, in some embodiments, the metered light sources  214  are used to provide the user with information relating to a positioning of the user on the running belt  104  of the treadmill  100 . For example, if the user is continuously running on the left side of the belt, the metered light sources may illuminate on the right side to indicate that the user should move slightly right on the treadmill  100 . As another example, a light source on a right side of the metered light sources  214  may illuminate when the user is running to a right of a center line of the running belt  104 . 
     In some embodiments, the light sources  320  may be individually controlled such that some light sources  320  are dynamically controlled (i.e., change in color and/or brightness based on inputs and settings), while other light sources  320  maintain static lighting (i.e., do not change in brightness or color). In some embodiments, the light sources  320  sync to music being played by the user or a class, such that the light sources  320  are dynamically controlled based on tempo, bass, volume, etc. to pulse, change color, brightness or transition from different settings. 
     In some embodiments, multiple treadmills  100  can be synced to one another or to a lead treadmill (e.g., a treadmill used by an instructor) or to a control device (e.g., computer, smartphone, tablet) of an instructor or leader of a class. Thus, control of the lighting system  150  may be performed via an instructor who may be situated in a same geographic location as the treadmill or completely remote from the treadmill  100 . The synced treadmills  100  may allow an instructor to provide cues to the users based on changes to the light sources  320  on the treadmill  100 . In some embodiments, the synced treadmills can provide a light indication of a position in a race (e.g., Prosmart competitions). In this configuration, the lighting system  150  may be set to display team colors. Additionally, the remote controller can simply control various outputs from the lighting system  150  (e.g., when certain colors are illuminated, the duration of that illumination, etc.). 
     In some instances, the treadmill  100  may be used underwater. As such, the lighting system  150  may display a color that is indicative of a temperature of the water for the treadmill  100 . For example, is the water is above a certain predefined threshold temperature, one or more light sources may illuminate red. If the water temperature is below the predefined threshold temperature, one or more light sources may illuminate green (to indicate a in “GO” message that the treadmill  100  is ready for use). Thus, one or more temperature sensors may be included with the treadmill  100  to acquire temperature data indicative of the water temperature. Such data may then be fed to the lighting system  150  for use. 
     The lighting system  150  may also provide cues to the user. As alluded to above, the metered light sources may be used to indicate to a user if he/she is running in the center or near center of the treadmill. Because the display may be turned off in the dark setting (perhaps based on an instructor&#39;s remarks), the running belt light source may illuminate different colors to indicate whether the user is running at the defined desired speed (e.g., green if the user is at or above the threshold, yellow if the user is within a certain amount of the threshold but still below said threshold, or red if the user is below the threshold by more than the certain amount, etc.). Thus, many different operational cues can be provided to the user via the lighting system  150 , such that the aforementioned list and description is not meant to be limiting. 
     Referring now to  FIG.  8    a flow diagram of a method  400  of using the lighting system  150  of  FIGS.  1 - 7    is shown, according to an exemplary embodiment. Method  400  includes storing preprogrammed light controls at  402 , receiving a user input at  404 , receiving data regarding operation of the treadmill  100  at  406 , and adjusting the light sources  320  at  408 . 
     Storing preprogrammed light control at  402  includes storing parameters relating to the control of the dynamic control of color, brightness, and transitions  304  based on at least one of a user input and data collected and/or determined. The dynamic control of color, brightness, and transitions  304  may cause color, brightness or a transition between color and brightness when a parameter of the data changes (e.g., transition from red to green when the user reaches a target heart rate range, increase in brightness as distance traveled increases, etc.). The dynamic control of color, brightness, and transitions  304  may be preset, or may provide parameters to the user via the display screen  204  that can be modified by the user via buttons  314 . The user may be able to adjust the color, brightness and/or transitions as well as change parameters that cause the changes in color, brightness or transitions. In some embodiments, the transitions include color transitions, brightness transitions or a combination thereof. In some embodiments, color and brightness schemes may be associated with the collected data or workout profiles selected by the user. For example, if the user selects a certain piece of data to monitor (e.g., heart rate, distance, speed, etc.), the lighting system  150  may include a predefined color and brightness scheme (e.g., blue for a first parameter, green for a second parameter, red for a third parameter, etc.) for the selected data. As another example, the lighting system  150  may provide multiple color and brightness schemes that the user can choose from once the monitored data is selected. For example, the lighting system  150  may include a first color and brightness scheme (e.g., one static color, brightness changes), a second color and brightness scheme (e.g., color changes, brightness is static), a third color and brightness scheme (e.g., color changes and brightness changes), etc. As still another example, when a workout profile (e.g., predefined changes in parameters such as resistance, incline, speed, etc. throughout a set period of time, distance, etc.) is selected, the lighting system  150  may include a predefined color and brightness scheme/routine associated with the changes in various parameters, similar to above. As yet another example, the lighting system  150  may provide multiple color and brightness schemes that the user can choose from once the workout profile is selected. As still a further example, the user may be able to independently control light sources  320  on a left side of the treadmill  100  and a right side of the treadmill  100 . In this regard, the user may be able to monitor two separate pieces of data by assigning one type of data to the light sources  320  on the left side of the treadmill  100  and assigning a second type of data, different from the first type of data, to the light sources  320  on the right side of the treadmill  100 . As yet a further example, a change may be indicated by a flash of light. For example, instead of changing a color or brightness level when a threshold is cross or a range is entered/exited for a type of data, the lighting system  150  may cause the light sources  320  associated with the data to blink, increase/decrease in brightness for a short period of time (e.g., flash), illuminate a different color for a short period of time, etc. 
     Receiving user input at  404  includes receiving workout metrics, workout programs, color, brightness, and/or transition selections. The user input may be received via buttons, a touchscreen of the display screen  204 , or other means of user input (e.g., via wired, wireless, wired and wireless connection, such as BLUETOOTH, USB, etc.). 
     The data received regarding operation of the treadmill  100  at  406  may include stride length, based on impulses in speed collected from impact of a foot of a user, time between impulses, and a distance traveled by the running belt  104 . The data collected may also include stride force, heart rate, cadence, pace, distance, resistance level, incline level, calorie count, time, carver counts, carver cadence, bounce, step count, ground contact time, vertical oscillation, and/or proximity of the user from the left, right, front and/or back of the running belt  104 . Data can be collected, or calculated, using the various sensors included with the treadmill  100  (e.g., sensors  208 ), information inputted using the display screen  204  and/or received from other devices, for example fitness watches, heartrate monitor straps, other wearable devices, a group workout leader device, etc. The data may also include workouts preprogrammed into the treadmill  100 . In some embodiments, a single data parameter is used for dynamic control of color, brightness, and transitions  304 . In some embodiments, a combination of data is used for dynamic control of color, brightness, and transitions  304 . In some embodiments, different light sources  320  receive different data for dynamic control of color, brightness, and transitions  304 . 
     In some embodiments, the dynamic control of color, brightness, and transitions  304  includes dynamic control of the metered light sources  214 . Dynamic control of the metered light sources  214  may incrementally light up based on increases in parameters of the data. In one embodiment, a single light source of the metered light sources  214  may illuminate when a certain parameter is obtained (e.g., a distance, a time, an incline level, etc.). In another embodiment, the metered light sources  214  are used to provide the user with information relating to positioning of the user on the running belt  104  of the treadmill  100 . For example, a light source on a right side of the metered light sources  214  may illuminate when the user is running to a right of a center line of the running belt  104 . Conversely, a light source on a left side of the metered light sources  214  may illuminate when the user is running to a left of a longitudinal center line of the running belt  104 . When the user is running in the longitudinal center of the belt  104 , the center light source or center portion of the metered light sources  214  may illuminate. These cues/indicators help the user understand their running, walking, or generally usage characteristics of the treadmill  100 , for example to help a user stay centered on the running belt  104  in a dark environment. 
     Various sensors may be used to determine the position of the user relative to the center line of the running belt  104  to facilitate control of the metered light sources  214  as described above. For example, force or load sensors may be distributed in the running belt  104  or in the base  102  to detect a location of a user&#39;s footsteps relative to the center line of the running belt. In other embodiments an array of laser-based distance sensors are positioned along the console and/or the handrails. The distance sensors may detect the proximity of the user&#39;s body to a handrail and/or the presence or absence of the user&#39;s body in various regions above the running belt  104 . In some embodiments, a camera captures images of the user on the running belt  104  and a machine vision approach is used to determine the position of the user relative to the center line of the running belt. These and other possibilities are contemplated by the present disclosure. 
     In some embodiments, the light sources  320  may be individually controlled such that some light sources  320  are dynamically controlled, while other light sources  320  maintain static lighting (i.e., unchanging). The light sources  320  may also sync to music being played by the user or a class, such that the light sources  320  are dynamically controlled based on tempo, bass, volume, etc. to pulse, change color, change brightness, or transition from different parameter settings. 
     In some embodiments, multiple treadmills  100  can be synced to one another or a lead treadmill (e.g., a treadmill used by an instructor). The synced treadmills  100  may allow an instructor to provide cues to the users based on changes to the light sources  320  on the treadmill  100 . In some embodiments, the synced treadmills can provide a light indication of a position in a race (e.g., Prosmart competitions). 
     In some embodiments, the lighting system  150  may be set to display team colors. In some embodiments, the lighting system  300  may display a temperature of water for the treadmill  100  (i.e., for underwater treadmills). In some embodiments, the lighting system  150  provides cues for running. Thus, the lighting system  150  adjusts the light sources  320  at  406  based on the preprogrammed light control, user input and data received, or a combination thereof as described above. 
     Referring now to  FIGS.  9 - 15   , a lighting system  550  for an exercise and therapeutic device, shown as a treadmill  500 , is depicted according to another exemplary embodiment. While a different reference number  500  is used to indicate the treadmill  500 , the treadmill  500  has the same structure and function as the treadmill  100  except that the treadmill  500  includes light sources not included with the treadmill  100 . Therefore, similar reference numbers are included with the treadmill  500  that were used with the treadmill  100  to refer to similar components. Accordingly and as described above, the treadmill  500  may be motorized or non-motorized, have a predominately flat or non-flat running surface (e.g., curved), and any of the other aforementioned described characteristics. Further, the lighting system  550  may be controlled via the controller  316 . As such, method  400  is equally applicable with the lighting system  550  of the treadmill  500 . Therefore, it should be understood that reference may be made to the controller  316 , inputs  302 , and outputs  318  to aid explanation of the lighting system  550 . Additionally, one or more of the light sources of the lighting system  550  may be included with the treadmill  100 ; alternatively, one or more of the light sources of the lighting system  150  may be included with the treadmill  500  and lighting system  550 . All such variations are intended to fall within the scope of the present disclosure. 
     With the above in mind and referring more particularly to  FIGS.  9 - 10   , as shown, the treadmill  500  includes a base  102 , handrails  106  mounted or coupled to the base  102 , a display device or console  200  coupled to the handrails  106 , a running belt  104  that extends substantially longitudinally along a center of the base  102 , and the lighting system  550 . From the viewpoint of the user facing the console  200 , the base  102  includes left and ride side panels  501  and  502  (e.g., covers, shrouds, etc.) that shield, cover, house, and/or protect various internal components of the treadmill  500  (and treadmill  100 , despite these panels not being called out in the earlier Figures). 
     In the example depicted in  FIG.  9    (and as shown in the earlier Figures), the running belt  104  is structured as a slatted running belt. A description of a construction of a slatted running belt is provided in U.S. Pat. No. 8,986,169, which is owned by the Applicant and incorporated herein by reference in its entirety. In an alternative embodiment, the running belt may be constructed as an endless belt, also referred to as a closed-loop treadmill or running belt (e.g., a non-slat embodiment). 
     Before turning to the lighting system  550 , referring more particularly now to  FIG.  14   , a depiction of the base  102  of the treadmill  500  with the side panels  501 ,  502 , the legs  112 , and various other components (e.g., front and rear shaft assemblies, the motor and motor assembly, etc.) removed is shown according to an exemplary embodiment. As shown, the base  102  includes a frame  510  which is an assembly of elements including longitudinally-extending, opposing side members, shown as a right side member  511  (first side member) and a left side member  512  (second side member) and one or more lateral or cross-members  513  extending between and structurally coupling the side members  511  and  512 . The frame  510  is adapted to support a front shaft assembly (not shown) positioned near a front end of the frame  510 , a rear shaft assembly (not shown) positioned near the rear end of frame  510 , a plurality of bearings  514  coupled to and extending generally longitudinally along the right side member  511  of the frame  510 , a plurality of bearings  515  coupled to and extending generally longitudinally along the left side member  512  of the frame  510 . The pluralities of bearings  514 ,  515  are substantially opposite each other about a longitudinal axis  18  of the running belt  104 . The pluralities of bearings  514 ,  515  are structured to support, at least partially, the running belt  104 . Additional description of these components, the arrangement thereof, and the functionality thereof (in combination with other components, such as a motor) is provided in U.S. patent application Ser. No. 15/640,180, which has the same Applicant and which is incorporated herein by reference in its entirety. Accordingly, the running belt  104  is coupled to the frame and configured to rotate about the one or more cross-members  513 . 
     With the above in mind, turning now to the lighting system  550  and  FIGS.  9 - 15    collectively, the lighting system  550  is shown to include a first lighting system  560  (e.g., internal lighting system), shown as light sources, specifically internal light sources, and a pair of second lighting systems, shown as light sources, specifically tail light sources or second lighting systems  580 . The lighting system  550  is operable in the same manner as described above with respect to the lighting system  150  where the controller  316  controls the color, brightness, static versus dynamic capability, remote controlling, frequency of blinking/staying at a color, actuation of some but not all light sources, and so on based on a predefined lighting routine, acquired data (e.g., stride information, etc.), and the like is equally applicable with the lighting system  550  (see, e.g., method  400 ). Therefore, the structure and arrangement, but not the function, of the lighting systems  560  and  580  are described below. 
     Referring first to the first lighting system  560  and in turn particularly  FIGS.  9 - 10  and  14 - 15   , the first lighting system  560  is disposed within the base  102  of the treadmill  500  and configured to emit or illuminate light out of the base  102  to illuminate, at least partly, the base  102  and the area surrounding the base  102 . As shown, the first lighting system  560  includes one or more light sources  561 , each of which are operable to emit light  562  (e.g., a beam, a beam of light, a glow, a radiance, etc.). The one or more light sources  561  have the same structure as the light sources  320 . In the example shown, the one or more light sources  561  are structured LED light sources (e.g., RGB LEDs, RGBW LEDs, etc.). However and as mentioned above, in another embodiment, the one or more light sources  561  may be any light type (e.g., fluorescent, halogen, incandescent, etc.) while in still other embodiments, the one or more light sources  561  may be any combination of LEDs and another light source. 
     With reference to  FIGS.  14 - 15   , one or more light sources  561  are coupled to the frame  510  within the base  102 , such that the running belt  104 , frame  510 , side panels  501 ,  502 , and other components cover or shield the light sources  561  when the treadmill  500  is assembled. As shown, the light sources  561  are coupled to the frame  510 . In particular, light sources  561  of the first lighting system  560  are coupled to each of the right side member  511 , a left side member  512 , and each of the cross-members  513 . As a result, the light sources  561  effectively outline the base  102  and include illumination sources from the middle area of the base  102  (where the cross-members  513  are positioned/disposed). 
     In operation, the one or more light sources  561  are structured to emit light  562  from within the base  102  (i.e., within the frame  510 , within a perimeter of the running belt  104 ). Because the light sources  561  are coupled to the cross members  513  and because the running belt  104  is slatted, the light  562  can pass through (e.g., shine through, radiate through, glow through, etc.) the crevices, gaps, or cracks between adjacent slats and on the sides of the belt  104  between the belt  104  and side panels  501 ,  502  and side members  511  and  512 . As the running belt  104  is moving at relatively faster rotational speeds, a user may effectively be able to see within the base  102  due to the light  562  illuminating the cracks between adjacent slats of the running belt. Further, the support surface beneath the base  102  may be illuminated due to no covers or shrouds being positioned underneath the cross-members (between the cross-members and the support surface). In dark use environments, this characteristics is beneficial for users to find the treadmill  500  and for other users to avoid stumbling into the treadmill  500 . 
     Thus, the one or more light sources  561  in the first lighting system lighting  560  emanate, provide, or otherwise discharge light from inside the perimeter of the running belt, which can be directed in any of the 360 degrees. Thus, the one or more light sources  561  mounted inside the frame  510  can shine up, forward, down, back, to the sides, etc. 
     In other embodiments, one or more light sources  561  may be coupled to different components of the frame  510  or base  102  (e.g., the light sources  561  may be coupled to one or both of the side panels  501  and  502 ). For example, light sources  561  may only be coupled to the side members, only the cross-members, only one cross-member, only one side member, and/or a combination thereof. Further, the precise placement of the light sources on these components is highly configurable. Additionally, the directional placement of the light sources  561  on these components is also highly configurable. For example, the light sources  561  may oriented towards the support surface for the treadmill  500  in order for the support surface proximate to and around the base  102  to be relatively greatly illuminated as compared to the direction vertically upwards from the support surface (i.e., towards the console  200 ). Such a configuration may be desirable in order for the light to not be too great that emanates outward and away from the belt  104 . Further, the exact number of light sources  561  included in the first lighting system  560  is also highly configurable. 
     In still some embodiments, holes or apertures may be defined in the side panels  501  and  502 . As a result, light sources  561  coupled to the side members  511  and  512  as well the cross-members  513  can emanate light through the side panels and outward and away from the treadmill  500 . As mentioned above, the direction of emanation is highly configurable. In this regard, in certain embodiments, one or more reflection devices (e.g., mirror, shiny panel, etc.) and/or lenses may be used to direct the emanated light  562  from the one or more light sources  561  in a variety of desired direction in order to achieve a variety of desired effects. 
     Turning now to the pair of second lighting systems  580  and primarily to  FIGS.  12 - 13   , each lighting system  580  includes a light source  581  that emanates light  582 , whereby the light source  581  is coupled to a housing  583  (also referred to as a reflective housing  583 ) structured to receive and redirect the emanated light  582  from the light source  581 . The light sources  581  in each second lighting system  580  are structured as LEDs like the light sources  561 . However and like the light sources  561 , other configurations of the light sources may also be utilized. 
     As shown, a light source  581  is coupled to the right side member  511  while a light source  581  is coupled to the left side member  512 . In particular, each light source  581  in each lighting system  580  is coupled to a lower panel/bracket of the side members  511  and  512  on the interior surface such that the body of the light source projects upward toward the running belt  104 . That is, each light source  581  is positioned interior to the base  102  and the belt  104  (i.e., within the frame  510 ). In this regard, the lower panel/bracket of each side member  511  and  512  is a barrier or intermediary between the support surface and each light source  581 . 
     Each light source  581  of each lighting system  580  is coupled to the lower panel/bracket of the left and right side members, respectively, in an orthogonal manner facing the support surface. In this regard, each light source  581  is facing or oriented vertically downwards towards the support surface. In other embodiments, the orientation or direction of emanation from the light sources  581  may be different than that depicted. 
     Each housing  583  in each lighting system  580  is also coupled to the lower panel/bracket of the left and right side members, respectively. However, each housing  583  is coupled to an exterior surface of the lower panel/bracket of the left and right side members  512  and  511 , respectively. Thus, each housing  583  is positioned proximate to the support surface and, particularly, between the support surface and the lower panel/bracket of the left and right side members  512 ,  511  of the frame  510 . As a result, each housing  583  is disposed in a substantial parallel arrangement to the support surface. As described below, the housings  583  are configured to direct the light emanated or provided from the light sources  581  in a desired direction. 
     Because the structure and function of each lighting system  580  is the same, the description provided below is only with respect to the second lighting system  580  that is coupled to the left member  512  as shown in  FIGS.  12 - 13   . However, it should be understood that a similar description is applicable with the second lighting system  580  coupled to the right side member  511 . 
     The housing  583  includes a first wall member  584  coupled to the left side member  512  of the frame  510 , a second wall member  585  coupled to the first wall member  584  and positioned in a parallel or substantial parallel orientation to the lower panel of the left side member  512  that the first wall member  584  is coupled to, and a lens  586  coupled to each of the second wall member  585  and the side member  512 . Collectively, the first wall member  584 , second wall member  585 , and lens  586  form a receptacle or collector for the provided light  582  from the light source  581 . In the depicted embodiment, the first and second wall members  584  may be discrete components that are coupled together (e.g., via one or more fasteners or adhesives). In another embodiment, the first and second wall members  584  and  585  may be of integral or uniform construction. In still another alternative embodiment, the first wall member  584  may be movably coupled to the second wall member  585 , which would enable the installer or technician to alter the angle of the first wall member  584  to the structure it is coupled to (e.g., the left side member  512 ) in order to customize and tailor the direction of the light  582  emitted. 
     As shown, the first wall member  584  extends outward and away from the side member  512  at an angle and towards the support surface, which is shown in  FIG.  13    and  FIG.  11    to provide a point of reference. The support surface may be a ground surface or other surface used to support the treadmill  500 . The first wall member  584  includes a reflective surface that is configured to reflect the beam of light  582  from the light source  581 . The reflective surface is disposed proximate to the receptacle and therefore at least partially facing the light source  581  (i.e., the surface that is adjacent to the beam of light  582  emitted from the light source  581  after the light  582  passes through the opening in the left side member  512 ). In one embodiment and as shown, the first wall member  584  is constructed from metal, such as sheet metal, that is adapted to reflect the light. In another embodiment, a reflective coating may be applied to the first wall member  584 . In yet another embodiment, a mirror may be used to reflect the light. In still another embodiment, the surface that reflects the light may be different from the exterior surface (i.e., proximate the support surface). All such configurations are intended to fall within the scope of the present disclosure. 
     In the example depicted, the lens  586  is structured as a clear acrylic piece of material that is coupled perpendicularly or substantially perpendicularly to the side member  512 . The lens  586  may focus the reflected light from the first wall member  584  (e.g., by including curvature with the lens or one or more lenses). The color and tint of the lens is highly configurable in order to achieve a light emitting characteristics (e.g., softer tones, brighter, dulled, etc.). It should be understood that a variety of form factors (e.g., curvatures, shapes, etc.), colors/tints, and materials may be used to construct the lens  586 . Accordingly, a variety of light manipulations from the lighting systems  580  is contemplated. 
     In yet other embodiments, the lens  586  may be omitted such that an opening, shown as opening  587 , is created between the second wall member  585  and the side member  512 . In this case, no additional light manipulation may be implemented to the emitted light  582  other than that from the light source  581  itself and via the reflective surface (e.g., no change of colors, focusing, brightening, dulling, etc. of the light  582 ). 
     Based on the foregoing, operation may be described as follows. The beam of light  582  is emitted from the light source  581  in a first direction (i.e., towards the support surface). The first wall member  584  reflects the light in a second direction, which is different from the first direction. In this example and due to the angle of the first wall member  584  relative to the support surface and side member  512 , the beam of light  582  is reflected and directed in a direction parallel to the lower panel/bracket of the side member  512  (based on the view depicted in  FIG.  13   ). As a result, the beam of light  582  is directed through the lens  586  and out towards a rear portion of the treadmill  500  (in a direction away from the console  200 ). As a result, the light sources  581  and second lighting systems  580  functions to illuminate or glow a rear end of the treadmill  500 , which beneficially enables users in dark environments to find the rear part of the treadmill  500  in order to properly board the treadmill  500 . Further and due to each lighting system  580  being positioned on each side of the running belt  104 , an alley-like glow is created to guide the user to the treadmill  500  and running belt  104 . 
     Beneficially, the positioning of the light sources  581  within the base  102  area and within the frame  510 , at least partly, functions to shield the light sources  581  from the external environment thereby protecting them from inadvertent harm. Of course, in other embodiments, the light sources  581  may be positioned outside the frame  510  area (e.g., within the housing  583 ). 
     In still other embodiments, the number, location, and orientation of the light sources  581  and housings  583  may change in other configurations. For example, one arrangement may orient the housing  583  in a plane perpendicular to the running belt  104  (i.e., traverse to the longitudinal direction of the running belt  104 ) such that the light  582  is directed laterally outward from the treadmill  500  (i.e., in a direction substantially perpendicular outward and away from a frontward or rearward direction—towards or away from the console  200 , respectively). In another example, the housing  583  may be positioned to orient the light  582  towards the front of the treadmill  500 . In yet another example, the light sources  581  and housing  583  may be disposed facing vertically upwards to direct vertically upwards and away from the support surface. Thus, the depiction of the housing  583  and light sources  581  coupled to lower part or bottom of the longitudinal side members  511  and  512  is not meant to be limiting as various other arrangements are intended to fall within the scope of the present disclosure.
