     DETAILED DESCRIPTION OF THE EMBODIMENT 
     In general, customers of gymnasiums and people who would like to stay fit may track data relating to their workout in order to improve their performance. Exercise machines, specifically aerobic machines like ellipticals and treadmills, can detect a user&#39;s heart rate, the number of calories burned, and the distance traveled. However, if a user wished to record such data, the user would have to manually enter it into his or her paper records, handheld device, computer, or other database. In fact, exercise machines that allow a user to lift weights do not calculate any workout-related data. This means that a user would have to remember and later record how much weight was lifted, how many reps were done, and how many sets were completed. Even if the user did remember to store the workout-related data, the user would still need to retrieve the data manually to determine how best to structure a future exercise routine in order to maximize performance. Accordingly, there is a need for a system that can automatically calculate workout-related data, store it at a central repository, and retrieve it at a later time to improve a user&#39;s workout performance. 
     In addition, many aerobic exercise machines may have pre-selected programs available for a user to select and run. For example, on an elliptical, a user may be able to select a program that simulates running on rolling hills, running uphill, or running downhill. However, these pre-selected programs only give a limited number of options to the users. The programs may allow a user to select distances to run in specified increments or an exact time to run in specified increments. Both male and female persons frequent gymnasiums or purchase exercise machines and are of all ages, heights, weights, and ethnicities. Accordingly, there is a need for a system that can execute any application of the user&#39;s choosing to ensure that the user is working out efficiently. 
     Accordingly, the systems and methods described herein can be used to improve workout performance. In an embodiment, the system automatically collects, stores, and retrieves a user&#39;s health and/or workout data. For example, a user&#39;s health and/or workout data can include, without limitation, age, sex, geographical location, ethnicity, the number of reps done, the number of sets completed, the time taken between reps, the time taken between sets, the amount of weight lifted, distance run, speed, number of calories consumed, number of calories burned, heart rate, wattage produced, exercise equipment used, which exercise equipment is used the most, which exercise equipment is used the least, the time of day the workout took place, the time of the year the workout took place, preexisting conditions, prior injuries, muscle gained, fat lost, or the like. 
     In further embodiments, the collected speed and/or heart rate data can be broken into time intervals such that a user could view his or her speed data or heart rate data between certain points during the exercise. Time intervals could be in the milliseconds, seconds, minutes, or the like. A user may find such information helpful in determining the time of peak performance or optimal ways to work out. In addition, such information can be useful to advertisers that produce advertisements for the system as described below. 
     In some embodiments, the number of calories consumed can be entered manually by the user via a website or other portal accessible via a network. In other embodiments, the number of calories consumed can be collected by a user&#39;s portable device, such as a cell phone, a smart phone, an iPod, an iPad, a tablet, a camera, a PDA, a laptop, or the like. For example, the user could input the number of calories consumed by verbally communicating with the user&#39;s portable device as to what food was eaten. Likewise, a portable device equipped with a near field communication (NFC) chip could be used to purchase food products to be consumed by the user. The portable device could then estimate the number of calories consumed by the user based on the food products purchased. Furthermore, a portable device could be used to take a photograph of a food product to be consumed by the user. The portable device can then compare the photograph taken with known food products in order to determine the type of food consumed and the number of calories consumed. The portable device can access a network such as the Internet in order to identify the food product in a given photograph. 
     In an embodiment, a user&#39;s health and/or workout data can be collected from the user directly through a website or other portal accessible via a network. The user&#39;s health and/or workout data can then be stored in a central repository. Alternatively or in conjunction, the user&#39;s health and/or workout data can be stored in a personal device, like a cell phone, a smart phone, a tablet, a PDA, a camera, a flash drive, a memory card, an optical disc, a laptop, a desktop, or the like. In another embodiment, the user&#39;s health and/or workout data can be collected from a handheld device associated with the user. The handheld device can then transmit the health and/or workout data to the central repository. In another embodiment, the user&#39;s health and/or workout data can be collected from an exercise machine in use by the user. To collect health data such as heart rate or the like, sensors can be attached to the handles or to a clip that the user can wear, or the data can be collected directly from the exercise machine in use (e.g., via sensors attached to, embedded within, or otherwise located within the exercise machine, etc.). The sensors may communicate measurements that are captured via a wired or wireless connection. When the user is exercising on an aerobic machine, sensors that can detect the number of revolutions can be used to collect workout data such as distance run, speed, calories burned, or the like. Such sensors can be located externally to the aerobic machine (e.g., attached to the aerobic machine) or can be embedded within the aerobic machine. When the user is exercising on a lifting machine, sensors like, without limitation, pressure sensors, accelerometers, or tension sensors, can be used to collect workout data such as the number of reps, the number of sets, the amount of weight lifted, wattage produced, or the like. Such sensors can be located externally to the lifting machine (e.g., attached to the lifting machine) or can be embedded within the lifting machine (e.g., within the structure of the lifting machine, within the weights of the lifting machine, etc.). When the user is exercising using medicine balls, dumbbells, other free weights, or the like, sensors like, without limitation, pressure sensors, accelerometers, or tension sensors, can be used to collect workout data such as the number of reps, the number of sets, the amount of weight lifted, wattage produced, or the like. Such sensors can be located externally to the medicine balls, dumbbells, other free weights (e.g., attached to the medicine balls, dumbbells, other free weights) or can be embedded within the medicine balls, dumbbells, other free weights. The exercise machine can transmit the health and/or workout data through a network to the central repository. 
     The health and/or workout data stored in the central repository can also be accessible by the user via a network connection. For example, the user can view the data at any time in a web browser. The data can be organized in charts, graphs, or any other visual representation. In addition, the data can be explained audibly for the visual impaired. 
     To improve the efficiency of a user&#39;s workout, the system can execute any application or applications of the user&#39;s choosing. In an embodiment, the application or applications executed can utilize the user&#39;s health and/or workout data retrieved from the central repository to send commands to an exercise machine, instructing the machine how to perform. An application can use some or all of the available user health and/or workout data. In another embodiment, the application or applications can extract health and/or workout data collected by an exercise machine to track a user&#39;s progress. In an additional embodiment, the application or applications can serve to entertain the user as the user performs his or her workout. In another embodiment, the application or applications can allow for at least two users to compete against one another. The application or applications can display each user&#39;s progress to the other such that at least two users could compete against one another even if there is a geographical distance separating the at least two users. 
       FIG. 1A  is a diagram illustrating an embodiment of an exercise machine  130  in communication with a network  110 . Exercise machine  130  can be an aerobic machine, lifting machine, or any other type of exercise equipment.

     Data from user application database  150 , user health information database  155 , and/or user entertainment database  160  can be accessible by using a uniquely identifiable key. This key can be based off of data acquired by user identifier device  120  regarding the user. In an embodiment, user identifier device  120  can generate this key and transmit it to exercise machine  130  and/or network communication device  140 . In another embodiment, user identifier device  120  can send data acquired from the user to exercise machine and/or network communication device  140 , and network communication device  140  can generate the key. 
     In some embodiments, one or more of the databases described above can be implemented using a relational database, such as DB2, Sybase, MySQL, Oracle, CodeBase, and Microsoft® SQL Server as well as other types of databases such as a flat-file database, an entity relationship database, and object-oriented database, and/or a record-based database. The databases described above can be stored in a central repository or in different locations. The databases can be housed in a server apparatus or in a personal device, like a cell phone, a smart phone, a PDA, a tablet, a laptop, a desktop, a camera, a flash drive, a memory card, an optical disc, or the like. Note that while  FIG. 1A  depicts three databases, other embodiments can include more or fewer databases depending on the type of data a user may request. As is described herein, network communication device  140  can run operating system software and a user can request data through a web-enabled user access point. Accordingly, a user can request any data available through network  110  and supported by the operating system software. 
       FIG. 1B  is a diagram illustrating an embodiment of exercise machine  130  in which network communication device  140  is embedded in exercise machine  130 . While embedded in exercise machine  130 , network communication device  140  can function as described above with respect to  FIG. 1A . Likewise, the communications between user identifier device  120  and exercise machine  130  and/or network communication device  140  remain as described above with respect to  FIG. 1A . Network communication  140  can still be in communication with network  110  in order to retrieve data stored in user application database  150 , user health information database  155 , and/or user entertainment database  160 . 
       FIG. 1C  is a diagram illustrating a user handheld device  180  that can acquire user health and/or workout data and communicate with a network  110 . User handheld device  180  can be any portable device, including, without limitation, a laptop, a PDA, a cell phone, a smart phone, a pager, a tablet, an iPod, a camera, or the like. For example, user  190  can be exercising while carrying user handheld device  180 , wearing user handheld device  180 , or otherwise being near user handheld device  180 . In some embodiments, one or more sensors are attached to user  190  and the measurements captured by the one or more sensors can be accessible by user handheld device  180  such that user handheld device  180  can transmit the health and/or workout data (e.g., data derived from the measurements captured by the one or more sensors) to user health information database  160  for storage. In other embodiments, one or more sensors can be attached to or included within the user handheld device  180  (e.g., coupled to the surface of user handheld device  180  via an electrical or mechanical connection, embedded within user handheld device  180 , etc.). For example, the user  190  can be wearing the user handheld device  180  and the one or more sensors attached to or included within the user handheld device  180  can be in contact with the user  190 . Measurements captured by the one or more sensors can be transmitted to the user handheld device  180  and the user handheld device  180  can transmit the health and/or workout data (e.g., data derived from the measurements captured by the one or more sensors) to user health information database  160  for storage. Note that user handheld device  180  can transmit health and/or workout data even if user  190  is not exercising. User handheld device  180  can transmit health and/or workout data related to any activity user  190  may be engaging in, including when user  190  is eating or idle In this way, all activities user  190  engages in can be monitored and stored for future use. 
       FIG. 2  is a diagram illustrating a more detailed network communication device  140 . Network communication device  140  includes an exercise routine module  260 , user identifier module  270 , and user application module  280 , which carry out the functions, methods, and/or processes described herein. Exercise routine module  260 , user identifier module  270 , and user application module  280  are each executed on the network communication device  140  by a central processing unit  220  discussed further below. 
     In general the word “module,” as used herein, refers to logic embodied in hardware or firmware or to a collection of software instructions, having entry and exit points. Modules are written in a program language, such as JAVA, JavaScript, HTML, XML, CSS, AJAX. PHP, C, C#, or C++, or the like. Software modules can be compiled or linked into an executable program, installed in a dynamic link library, or can be written in an interpreted language such as BASIC letters, ASP, PERL, LUA, PHP, Ruby, Python, or the like. Software modules can be called from other modules or from themselves, and/or can be invoked in response to detected events or interruptions. Modules implemented in hardware include connected logic units such as gates and flip-flops, and/or can include programmable units, such as programmable gate arrays or processors. 
     Generally, the modules described herein refer to logical modules that can be combined with other modules or divided into sub-modules despite their physical organization or storage. The modules are executed by one or more computing systems, and can be stored on or within any suitable computer readable medium, or implemented in-whole or in-part within special designed hardware or firmware. Not all calculations, analysis, and/or optimization require the use of computer systems, though any of the above-described methods, calculations, processes, or analyses can be facilitated through the use of computers. Further, in some embodiments, process blocks described herein can be altered, rearranged, combined, and/or omitted. 
     Network communication device  140  includes one or more central processing units (CPU)  220 , which can include a microprocessor. Network communication device  140  further includes a memory  240 , such as random access memory (RAM) for temporary storage of information, a read only memory (ROM) for permanent storage of information, and a mass storage device  250 , such as a hard drive, a flash drive, a memory card, a diskette, an optical media storage device, or the like. Alternatively, the mass storage device can be implemented in an array of servers. Typically, the components of the network communication device  140  are connected to the computer using a standards based bus system. The bus system can be implemented using various protocols, such as Peripheral Component Interconnect (PCI), Micro Channel, SCSI, Industrial Standard Architecture (ISA) and Extended ISA (EISA) architectures. 
     Network communication device  140  includes one or more input/output (I/O) devices and interfaces  210 , such as a keyboard, mouse, touchpad, and printer. The I/O devices and interfaces  210  can include one or more display devices, such as a monitor, that allows the visual presentation of data to a user. More particularly, a display device provides for the presentation of GUIs as application software data, and multi-media presentations, for example. The I/O devices and interfaces  210  can also provide a communications interface to various external devices. The network communication device  140  can include one or more multi-media devices  230 , such as speakers, video cards, graphics accelerators, and microphones, for example. 
     Network communication device  140  can run on a variety of computing devices, such as a server, a virtual server, a Windows server, and Structure Query Language server, a Unix Server, a Linux Server, a Mac Server, a personal computer, a laptop computer, and so forth. In other embodiments, network communication device  140  can run on a mainframe computer suitable for controlling and/or communicating with large databases, performing high volume transaction processing, and generating reports from large databases. Network communication device  140  is generally controlled and coordinated by an operating system software, such as z/OS, Windows 95, Windows 98, Windows NT, Windows 2000, Windows XP, Windows Vista, Windows 7, Linux, Unix, BSD, SunOS, Solaris, tinyOS, iOS, Windows Mobile, Android, webOS, or other compatible operating systems, including proprietary operating systems. Operating systems control and schedule computer processes for execution, perform memory management, provide fide system, networking, and I/O services, and provide a user interface, such as a graphical user interface (GUI), among other things. 
     Network communication device  140  is coupled to a network  110 , such as a LAN, WAN, or the Internet via a communication link (wired, wireless, or a combination thereof). Network  110  communicates with various computing devices and/or other electronic devices. User application module  280  can access or can be accessed through a web-enabled user access point. Connections can be a direct physical connection, a virtual connection, and other connection type. The web-enabled user access point can include a browser module that uses text, graphics, audio, video, and other media to present data and to allow interaction with data via network  110 . The browser module can display media associated with an application as well. 
     The browser module can also present advertisements based on identifiable or non-identifiable health and/or workout data captured by exercise machine  130  and/or stored in user health information database  155 . Health and/or workout data captured by exercise machine  130  during the showing of a given advertisement can be relayed to the advertisers to provide feedback on the effectiveness or usefulness of an advertisement. For example, if a user&#39;s heart rate data spikes during the showing of a particular advertisement or if a user temporarily slows down during the showing of a particular advertisement, an advertiser can be notified that the advertisement may be pertinent to other individuals with similar health and/or workout data. Likewise, feedback on the effectiveness or usefulness of an advertisement can be transmitted for use in search engines. In this way, a user&#39;s health and/or workout data can be used to generate feedback on advertisements and, in conjunction with already accumulated user data, like web habits, can be used to produce more targeted and effective advertising. The same applies to e-commerce stores, where a user&#39;s health and/or workout data can be used to generate feedback on advertisements and, in conjunction with already accumulated user data, like spending habits, can be used to produce more targeted and effective advertising. 
     The browser module or other output module can be implemented as a combination of an all-points addressable display such as a cathode ray tube (CRT), a liquid crystal display (LCD), a plasma display, a field emission display (FED), a surface-conduction electron-emitter display (SED), a light-emitting diode display (LED), an organic light-emitting diode display (OLED), an active-matrix organic light-emitting diode display (AMOLED), or other types and/or combinations of displays. The output module can be implemented to communicate with input devices  210  and they also include software with the appropriate interfaces which allow a user to access data through the use of stylized screen elements, such as menus, windows, dialogue boxes, tool bars, and controls (e.g., radio buttons, check boxes, sliding scales, and so forth). Furthermore, the output module can communicate with a set of input and output devices to receive signals from the user. 
     In an embodiment, user identifier module  270  receives user identification data from user identifier device  120 , either directly or indirectly through exercise machine  130 , and generates a key that can be used to extract data from user application database  150 , user health information database  155 , and/or user entertainment database  160  that corresponds to the user in question. 
     User application module  280  can receive at least one application relating to the user from user application database  150 . In some embodiments, user application module  280  can also contain pre-selected applications, designated by the gymnasium, manufacturer, or other third party. In further embodiments, user application module  280  can also receive entertainment data from user entertainment database  160 . User application module  280  can execute the at least one application based on a user preference. For example, the user can select one or more applications to execute through the web-enabled user access point. 
     Applications can be any program that could be executed by the operating system software loaded in network communication device  140 . In an embodiment, an application could generate an exercise regimen for the user based on health and/or workout data received from user health information database  155 . Once executed, user application module  280  could instruct exercise routine module  260  to generate command signals to control how exercise machine  130  functions. For example, in situations in which exercise machine  130  is an aerobic machine, exercise routine module  260  could send command signals to exercise machine  130  to instruct it to simulate running on an incline by adjusting the tension and/or slope of exercise machine  130 . Furthermore, an application can simulate an actual geographical route, like a trail in Yosemite, by instructing exercise routine module  260  to send command signals to exercise machine  130  such that the tension and/or slope is adjusted according to the layout of the actual geographical route. 
     In addition, an application could inform the user of the particular exercise it is recommending through the web-enabled user access point or other display device. For example, in situations in which exercise machine  130  is a lifting machine, the web-enabled user access point or other display device could speak, display text, make a noise, vibrate, and/or flash a light to indicate to the user that he or she should do a certain number of reps or that the person has completed a particular set. If an application determines that the user should exercise on a different exercise machine, this information could be displayed or verbally spoken to the user through the web-enabled user access point as well. 
     In another embodiment, an application could play music or video based on entertainment data received from user entertainment database  160 . In this way, a user would not need to bring his or her portable music and/or video device, like a cell phone, smart phone, cassette player, optical disc player, music file player, video file player, or the like, to listen to his or her own music or watch his or her own videos. 
       FIG. 3  is a diagram illustrating at least two network communication devices  340 ,  350 , and/or  390  that can interact with each other through network  110  and host server system  380 . In an embodiment, at least two users can exercise together and compete in real-time. For example, the at least two network communication devices  340 ,  350 , and/or  390  can all execute an identical application or applications. Alternatively, one of the at least two network communication devices  340 ,  350 , and/or  390  can execute an application. The network communication device  340 ,  350 , or  390  that executes the application can then generate command signals to control each of the exercise machines  330  and  360  in communication with the at least two network communication devices  340 ,  350 , and/or  390 . Host server system  380  can serve as an intermediary device, establishing a forum in which users can find each other, hosting data related to each user&#39;s performance, and relaying such data to the other users. Each user can track his or her progress through the web-enabled user access point or other display device and compare his or her performance against the others also exercising at the same time. The application or applications executed by the at least two network communication devices  340 ,  350 , and/or  390  can be any application that could be executed by the loaded operating system software. In this way, multiple users can exercise together even when geographically separated. 
     In another embodiment, at least two users can compete against one another even if they are not exercising together in real-time. Host server system  380  can store exercise information relating to a first user who exercised earlier than a second user. For example, host server system  380  can store the time it took for a first user to complete the exercise and/or how far the first user had run at a given point in time. When the second user begins his or her first exercise, he or she can view the first user&#39;s performance data in the web-enabled user access point or other display device. In this way, multiple users can exercise together even when their schedules dictate that they work out at different times of the day. 
     Note that while at least two users are competing and/or exercising with each other, each user&#39;s health and/or workout data can still be collected and stored in user health information database  160 . Likewise, each user, by signing in via user identifier devices  320  and/or  370 , can load and execute their own personal applications while exercising with others. For example, a user can load and execute an application that plays the user&#39;s music while racing against another user. 
     Host server system  380  can support any number of users. In this way, users can compete remotely in large-scale events, like a 10K race or a marathon. 
       FIG. 4  is a diagram illustrating user communication device  420  is similar to network communication device  140  as described above in  FIGS. 1A, 1B, and 2 . User communication device  420 , however, does not communicate directly with network  110 . Instead, user handheld device  430  serves as an intermediary between user communication device  420  and network  110 . For example, if exercise machine  410  is not equipped with networking capabilities or it is otherwise impractical for exercise machine  410  to be in communication with network  110  in the gymnasium, user handheld device  430  can allow exercise machine  410  and user communication device  420  to communicate with network  110 . 
     User handheld device  430  can be any device that can communicate with a network such as, without limitation, a cell phone, a smart phone, a PDA, a pager, a tablet, a laptop, a camera, a music and/or video player, a modem, a router, or the like. User handheld device  430  can communicate with user communication device  420  through wired or wireless communications. In an embodiment, user handheld device  430  can be physically docked to user communication device  420 . User handheld device  430  can connect to user communication device  420  via Ethernet, USB 1.0, USB 2.0, USB 3.0, IEEE 1394, IEEE 1394a, IEEE 1394b, Thunderbolt, VGA, DVI, HDMI, optical fiber, serial port, parallel port, or the like. In other embodiments, user handheld device  430  can communicate with user communication device wirelessly via Bluetooth, NFC technology, the 802.11 standard, the 802.15.4 standard, RFID or the like. Likewise, user handheld device  430  can communicate with network  110  through similar wired or wireless standards. 
     User handheld device  430  can retrieve data from user application database  150 , user health information database  155 , and/or user entertainment database  160  for use by user communication device  420 . User communication device  420  can utilize such data in the same way as network communication device  140  as described above with respect to  FIGS. 1A, 1B, and 2 . Likewise, user handheld device  430  can receive health and/or workout data from user communication device  420  and/or exercise machine  410  for storage in user health information database  155 . 
     In an embodiment, a user identifier device  120 , as described above with respect to  FIGS. 1A, 1B, and 2 , may not be necessary in order to uniquely identify an individual. A user using a personal user handheld device  430  can log in via user handheld device  430 . In this way, even if a user is borrowing another person&#39;s user handheld device  430 , the user can still retrieve and store his or her personal health and/or workout data. In other embodiments, a user identifier device similar to user identifier device  120  in  FIGS. 1A, 1B, and 2  can be in communication with exercise machine  410 . For example, some user handheld devices  430  may not have the means to allow a user to uniquely identify him or herself. A user identifier device similar to user identifier device  120  could be used to uniquely identify an individual, and user handheld device  430  could obtain this identity information to retrieve the appropriate data. 
       FIG. 5  is a diagram illustrating a more detailed user communication device  420 . User communication device  420  can include eight modules: I/O devices and interfaces  510 , at least one central processing unit (CPU)  520 , multimedia devices  530 , memory  540 , mass storage device  550 , exercise routine module  560 , user identifier module  570 , and user application module  580 . In an embodiment, these modules function as their similarly named counterparts in network communication device  140  and as described with respect to  FIG. 2 . 
       FIG. 6  is a flowchart illustrating a process for loading and executing at least one application in network communication device  140  or user communication device  420 . The process begins at block  610  with the process receiving user identification information from user identifier device  120  and/or exercise machine  130  as described above with respect to  FIG. 1A . At block  620 , the process transmits the user identification data to user application database  150 , user health information database  155 , and/or user entertainment database  160 . In some embodiments, the process can generate a key or other database query code based on the user identification data. This key or code can be sent to all or some of the three databases to retrieve the requested data. At block  630 , the process receives health and/or workout data, entertainment data, and/or application data from some or all of the three databases. 
     At block  640 , the process identifies at least one application selected by the user. In an embodiment, the user can select an application using the web-enabled user access point or other display device as described herein. In some embodiments, the at least one application can be an application pre-selected by the gymnasium or manufacturer of exercise machine  130  and stored in network communication device  140 . In other embodiments, the at least one application can be an application acquired by the user and stored in user application database  150 . 
     At block  650 , the process executes the at least one selected application to generate an exercise routine for the user on the exercise machine the user is currently operating. In addition, the execution can result in the generation of command signals to control operation of the exercise machine. In some embodiments, the execution can generate a message instructing the user to exercise on a different machine and provide an exercise routine for the different machine. 
     At block  660 , the process transmits the generated command signals to an exercise machine being used by the user. As described herein, for example, the command signals can adjust the tension and/or slope of the exercise machine. 
     At block  670 , the process receives health and/or workout data from exercise machine  130  generated by the user&#39;s exercising. As described herein, received health and/or workout data can include, without limitation, the number of reps done, the number of sets completed, the time taken between reps, the time taken between sets, the amount of weight lifted, distance run, speed, number of calories burned, heart rate, wattage produced, exercise equipment used, which exercise equipment is used the most, which exercise equipment is used the least, the time of day the workout took place, the time of the year the workout took place, preexisting conditions, prior injuries, muscle gained, fat lost, or the like. 
     At block  680 , the process transmits the received health and/or workout data to user health information database  155 . The process can automatically enter the data into the correct field based on a key or code generated from the user identification data, or based on the user identification data itself. At block  690  the process ends. 
       FIG. 7  is a flowchart illustrating a process for loading and executing at least one application on at least two exercise machines to allow at least two users to exercise and/or compete with each other. The process begins at block  705  and at block  710 . At block  705 , the process initiates a competition program. The process occurs at a first network device, which can be similar to network communication device  140  or user communication device  420  as described above with respect to  FIGS. 1A, 1B, 2, and 4 . In some embodiments, the competition program can be obtained from user application database  150 . In other embodiments, the competition program can be pre-stored in network communication device  140  or user communication device  420 . 
     At block  710 , the process, at a second network device, transmits its availability to a host server, indicating that a second user is available to connect to others. Like with the first network device, the second network device can be similar to network communication device  140  or user communication device  420 . The host server can be similar to host server system  380  as described above with respect to  FIG. 3 . Alternatively, not shown, the process can initiate the same competition program at the second network device as at the first network device. This can allow the process to later visualize the performance of each user in a uniform display viewable by both users. 
     At block  715 , the process, at the host server, transmits information relating to available competitors to the first user through the first network device. Note that the host server and the first network device and the host server and the second network device can be in communication with each other through a network, like network.  110  as described with respect to  FIGS. 1A-C  and  2 - 5 . Accordingly, the host server is not limited in the number of users it can identify as being available. 
     At block  720 , the process, at the first network device, identifies at least one competition selected by the first user. The first user can select one or more competitors through the web-enabled user access point, as described herein. 
     At block  725 , the process, at the second network device, accepts a connection to the first network device. When the first user selects more than one available competitor, the process, at each addition network device, could accept a connection to the first network device. 
     At block  730 , the process, at the first network device, identifies at least one selected application acquired by the first user and received from the user application database  150 . Alternatively, not shown, the process can identify at least one application selected by the first user that was already pre-loaded at the first network device. 
     At block  735 , the process, at the first network device, executes the at least one selected application to generate an exercise routine. The exercise routine can be based on the first user&#39;s health and/or workout data acquired from user health information database  155 . Alternatively, not shown, the process, at both the first network device and the second network device, can execute the same application. Again, this can allow the process to later visualize the performance of each user in a uniform display viewable by both users. 
     At block  740 , the process, at the first network device, transmits command signals to a first exercise machine and the second network device based on the generated exercise routine. Note that even if the process executes the application at the second network device, the process can still transmit the command signals to the second network device to ensure that both users are competing on an equal playing field. 
     At block  745 , the process, at the second network device, receives command signals from the first network device based on the generated exercise routine. At block  750 , the process, at the second network device, transmits these command signals to a second exercise machine. As described herein, the command signals can adjust the tension and/or slope of the second exercise machine. 
     At block  755 , the process, at the first network device, receives health and/or workout data from the first exercise machine. At block  760 , the process, at the first network device, transmits the received health and/or workout data to the user health information database  155  and/or the host server. In some embodiments, the host server may only receive data that is sufficient for each user to compare their progress against the other. 
     At block  765 , the process, at the second network device, receives health and/or workout data from the second exercise machine. At block  770 , the process, at the second network device, transmits the received health and/or workout data to the user health information database  155  and/or the host server. In some embodiments, the host server may only receive data that is sufficient for each user to compare their progress against the other. 
     At block  775 , the process, at the host server, receives health and/or workout data from each user and transmits the same to the other user. In addition, not shown, the process can display performance data at the first network device and the second network device. The performance data can be based on the health and/or workout data received by the host server. At block  780 , the process ends. 
     In other embodiments, not shown, at least two users can compete against each other at different times. For example, in this instance, the process would not need to initiate contact between the first network device and the second network device. A user at the first network device could complete his or her workout and the process could transmit the workout information and any exercise machine command signals to the host server. When a second user wishes to compete against a first user that has already completed his or her exercise, the process could transmit the workout information and any exercise machine command signals to the second network device. In this way, the second user could participate in the same exercise routine as the first user and compare his or her performance. 
       FIG. 8  is a diagram illustrating a system to power and/or charge hybrid and/or electric automobiles, airplanes, motor boats, motorcycles, scooters, or other like motor vehicles. Exercise machines  810  can be located in a gymnasium or other such establishment. While exercise machines  810  are in use, electrical energy can be generated. This electrical energy can be stored in storage device  815  for future use via transmission along transmission bus  820 . Energy storage device  815  can be a capacitor or a rechargeable battery, such as, without limitation, lead acid, lithium ion, lithium ion polymer, nickel cadmium, nickel metal hydride, or reusable alkaline. Transmission bus  820  can be any type of line that can carry electrical current including, without limitation, a coaxial cable, a microstrip, a stripline, a balanced line, a twisted pair, a star quad, a twin-lead, a lecher line, a single-wire line, a waveguide, an optical fiber, or the like. 
     In some embodiments, the electrical energy can be transmitted along transmission bus  820  to other device charging stations  830 ,  840 ,  850 , and/or  860 . Other devices  835 ,  845 ,  855 , and/or  865  can be coupled to any of other device charging stations  830 ,  840 ,  850 , and/or  860 . Other devices  835 ,  845 ,  855 , and/or  865  and other device charging stations  830 ,  840 ,  850 , and/or  860  can be coupled wirelessly or through wired communications. For example, without limitation, the connection can be inductive or through a cable like USB or IEEE 1394. 
     Other device charging stations  830 ,  840 ,  850 , and/or  860  can be equipped to charge hybrid and/or electric motor vehicles, such as automobiles, airplanes, motor boats, motorcycles, scooters, or the like. In addition, other device charging stations  830 ,  840 ,  850 , and/or  860  can be equipped to charge personal devices, such as cell phones, smart phones, PDAs, pagers, tablets, cameras, music and/or video players, laptops, or the like. Other device charging stations  830 ,  840 ,  850 , and/or  860  can be located near a gymnasium or other establishment such that they can draw electrical energy from users exercising on exercising machines  810 . 
     When none of other device charging stations  830 ,  840 ,  850 , and/or  860  are in use, electrical energy that is generated can be stored in energy storage device  815 . Likewise, when none of exercise machines  810  are in use, other device charging stations  830 ,  840 ,  850 , and/or  860  can draw electrical energy from energy storage device  815  in order to charge other devices  835 ,  845 ,  855 , and/or  865 . Note that this embodiment is not limited to four charging stations or four other devices, nor does it require that at least four charging stations be built. 
     In an embodiment, the amount of electrical energy available to charge an other device  835 ,  845 ,  855 , or  865  can depend on the amount of exercise completed by a user associated with the other device  835 ,  845 ,  855 , and/or  865 , For example, when initially docking his or her other device  835 ,  845 ,  855 , and/or  865  for charging, a user can sign in to other device charging station  830 ,  840 ,  850 , and/or  860 . A user can sign in using a module similar to user identifier device  120  described herein with respect to  FIGS. 1A, 1B, and 2 . Likewise, a user can then subsequently sign in to an exercise machine  810  using a module similar to user identifier device  120  described herein with respect to  FIGS. 1A, 1B, and 2 . By signing in, the system can associate a particular exercise machine  810  a user is operating with the other device charging station  830 ,  840 ,  850 , and/or  860  that the user&#39;s other device  835 ,  845 ,  855 , and/or  865  is docked at. Each exercise machine  810  can track the amount of wattage generated by the user operating it and transmit this data to energy allocation controller  825 . 
     Energy allocation controller  825  can be any device that can control the output of energy storage device  815 . Energy allocation controller  825  can tally the total amount of wattage generated by all exercise machines  810  and then assign a percentage value to each user based on the amount of energy each user contributed to the total. Energy allocation controller  825  can then direct energy storage device  815  to distribute a percentage of its total stored energy to the other device charging station  830 ,  840 ,  850 , and/or  860  associated with the user, where the distributed percentage is based on the percentage value assigned to the user. 
     In other embodiments, not shown, the electrical energy produced can be used to power the gymnasium or other such establishment itself. The amount of energy generated by a particular user could be tracked by exercise machines  810  and/or energy allocation controller  825 , such that the user&#39;s membership dues are reduced proportionally or directly by the cost of energy he or she produced. Transmission bus  820  can also be coupled with the main power grid, and the electrical energy could be sold back to the utility company.
