executing, at the local location, the video workout program to continuously control one or more moveable members of the exercise machine using the exercise machine control commands at a current difficulty level, to continuously display the video, and to continuously monitor an actual heart rate of a user;
periodically determining at least:
that an actual heart rate zone of the user is not equal to a current programmed heart rate zone, and
that the actual heart rate of the user is not trending toward the current programmed heart rate zone by at least a threshold heart rate trend rate; and
in response to the periodically determining, adaptively scaling the video workout program by adjusting the current difficulty level:
upward if the actual heart rate zone is lower than the current programmed heart rate zone, or
downward if the actual heart rate zone is higher than the current programmed heart rate zone.
2. The method of claim 1 , wherein:
changes in the exercise machine control commands of the video workout program are synchronized with associated changes in the depiction of the trainer performing the workout in the video of the video workout program; and
changes in the control of the one or more moveable members of the exercise machine occur synchronously with associated changes in the workout being displayed in the video.
3. The method of claim 1 , further comprising:
transmitting the video workout program from the remote location to the local location in a live broadcast to enable:
the decoding and executing to occur during the trainer performing the workout at the remote location; and
performance of the workout on the exercise machine by the at the local location that mimics the trainer performing the workout at the remote location.
4. A method for controlling an exercise machine using a video workout program, the method comprising:
encoding, remotely from the exercise machine, exercise machine control commands into a subtitle stream of a video to create the video workout program, wherein the exercise machine control commands are encoded as comma separated values (CSVs) such that the position of each value corresponds to a different parameter of the exercise machine;
decoding, locally to the exercise machine, the subtitle stream of the video to access the exercise machine control commands;
displaying, locally to the exercise machine, the video; and
controlling, locally to the exercise machine, one or more moveable members of the exercise machine using the exercise machine control commands, according to the parameters of the exercise machine encoded as CSVs.
5. The method of claim 4 , wherein the CSVs further include workout data associated with a workout depicted in the video of the video workout program.
6. The method of claim 5 , wherein the workout data includes one or more of:
a target revolutions per minute (RPM) for the workout;
a target watts for the workout;
a target heart rate zone for the workout;
a target heart rate for the workout;
a current number of seconds since a start of the workout; and
a workout state of the workout, the workout state including a warmup state, an in-workout state, or a cooldown state.
7. The method of claim 5 , wherein:
changes in the exercise machine control commands of the video workout program are synchronized with associated changes in the workout depicted in the video of the video workout program; and
changes in the control of the one or more moveable members of the exercise machine occur synchronously with associated changes in the workout being displayed in the video.
8. The method of claim 5 , further comprising:
capturing, remotely from the exercise machine, the video depicting the workout.
9. The method of claim 8 , wherein the encoding of the exercise machine control commands into the subtitle stream of the video is performed subsequent to the capturing of the video.
10. The method of claim 8 , wherein the encoding of the exercise machine control commands into the subtitle stream of the video is performed synchronously with the capturing of the video.
11. The method of claim 8 , further comprising:
transmitting the video workout program from a location remote from the exercise machine to a location local to the exercise machine in a live broadcast to enable:
the decoding, displaying, and controlling to occur during the trainer performing the workout at the location remote from the exercise machine; and
performance of the workout on the exercise machine by a user at the location local to the exercise machine that mimics the trainer performing the workout at the location remote from the exercise machine.
12. The method of claim 4 , wherein the exercise machine control commands are configured to control one or more of:
a speed of the one or more moveable members of the exercise machine;
an incline percentage of the one or more moveable members of the exercise machine; or
a resistance of the one or more moveable members of the exercise machine.
13. A method for controlling an exercise machine using a video workout program, the method comprising:
executing, at the exercise machine, the video workout program, the exercise machine including one or more moveable members, the video workout program including a video depicting a trainer performing a workout, the video workout program further including multiple programmed heart rate zones corresponding to the depiction of the trainer in the video;
continuously controlling the one or more moveable members at a current difficulty level;
continuously displaying the video;
continuously monitoring an actual heart rate of a user;
periodically determining at least:
that an actual heart rate zone of the user is not equal to a current programmed heart rate zone, and
that the actual heart rate of the user is not trending toward the current programmed heart rate zone by at least a threshold heart rate trend rate; and
in response to the periodically determining, adaptively scaling the video workout program by adjusting the current difficulty level:
upward if the actual heart rate zone is lower than the current programmed heart rate zone, or
downward if the actual heart rate zone is higher than the current programmed heart rate zone.
14. The method of claim 13 , wherein the periodically determining further includes periodically determining at least:
