A method includes receiving electronic content via a network, the electronic content comprising an exercise class, and receiving user data associated with a user participating in the exercise class using an exercise machine. The method also includes generating an executable control for a user interface based at least in part on the user data, and providing the executable control, via a display of the exercise machine, while the user is participating in the exercise class. In such a method, the executable control is operable to modify a parameter of the exercise machine while the user is participating in the exercise class.

An incline mechanism for a treadmill includes a threaded rod supported by an upright structure. The threaded rod and a lift motor are connected to the upright support above the front end of an exercise deck. The threaded rod is threaded onto a threaded coupler. The threaded coupler is connected to a lift trolley connected to the front end of the exercise deck. As the lift motor rotates the threaded rod, the threaded coupler may move along the length of the threaded rod, thereby changing the inclination of the exercise deck.

A treadmill includes a deck having a continuous track, and a plurality of slats fixedly connected to the track. The treadmill also includes a first post extending from the deck, a second post extending from the deck opposite the first post, and a first arm supported by the first post and including a first rotary control. The treadmill further includes a second arm opposite the first arm and supported by the second post. The second arm includes a second rotary control separate from the first rotary control. The first rotary control is configured to control a first function of the treadmill and the second rotary control is configured to control a second function of the treadmill different from the first function.

An exercise system for incorporating physical exercise with sedentary job tasks includes a treadmill that may be walked upon. A workstation is coupled to the treadmill and the workstation is accessible when the treadmill is walked upon. Thus, job tasks may be undertaken simultaneously with physical exercise.

Disclosed are various approaches for determining the maximum oxygen consumption of a person, also known as maximum aerobic capacity or VO.sub.2 Max. A person is positioned on a treadmill. Attached to the person is a harness configured to apply a horizontal force to the person. A work rate for the person can be calculated based at least in part on the magnitude of the horizontal force applied by the harness and the velocity of the belt. The maximum oxygen consumption for the person can then be calculated based at least in part on the previously calculated work rate.

An electric training apparatus is configured to apply, by a load motor, a load on a rotating body configured to apply a load on an exercising person, detect an exercise physiological response value of the exercising person and a number of revolutions of the rotating body, perform control for gradually increasing the load of the load motor toward a set load upper limit value so that a detection result of the exercise physiological response value of the exercising person approaches a target exercise physiological response value set in advance, and change, before an exercise or during the exercise by the exercising person, the load upper limit value in response to a control command input based on a state of the exercising person, a state of the control, and a perceived exertion scale for the exercising person.

A method for adjusting a working state of an electronic device includes setting a reasonable value range of feature data of a user, and acquiring current feature data of the user from the camera device. The current feature data is compared to the reasonable value range of feature data. A working state of the electronic device is changed when the current feature data is out of the reasonable value range of feature data.

A method for controlling breathing of a user during workout with an exercise machine is provided. The method includes acquiring, by a data processing unit of the exercise machine, at least one parameter representative of a physical exercise being performed by the user with the exercise machine, determining, by the data processing unit of the exercise machine, an indication of the breathing to be followed by the user while performing the physical exercise based on the acquired at least one parameter representative of the physical exercise, and providing the user, by the data processing unit of the exercise machine, with the determined indication of breathing. An exercise machine implementing the method for controlling breathing of the user during workout is also provided.

Controlling an exercise machine using a video workout program. In one aspect of the disclosure, a method may include capturing a video, encoding exercise machine control commands into a subtitle stream of the video to create the video workout program, decoding the subtitle stream of the video to access the exercise machine control commands, periodically determining at least that an actual heart rate zone of a 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 adaptively scaling the video workout program by adjusting a current difficulty level upward or downward depending on if the actual heart rate zone is lower or higher than the current programmed heart rate zone, respectively.

A treadmill and a control method for controlling the treadmill belt thereof are provided. The treadmill includes a treadmill belt, a first sensor, an image sensor, and a controller. The first sensor retrieves a light pattern or the image sensor measures the characteristic properties of the image of the user so as to control the treadmill belt. The light pattern can be generated by a signal member, which can be disposed on a side or both sides of the treadmill belt.
