A method is provided for the automatic control of cycling speed in a human. The method comprises: estimating the subject's actual cycling speed using one or more sensors to thereby obtain a measured speed; determining an error comprising a difference between a desired speed and the measured speed; and outputting, to the subject, a stimulus frequency signal wherein the stimulus frequency signal is based on the error in such a manner that when the subject pedals in a manner that matches a frequency of the stimulus frequency signal, the subject's actual speed controllably tracks the desired speed.

Stationary exercise machine. In one aspect of the disclosure, a stationary exercise machine may include one or more moveable members configured to be moved by a user, an actuator configured to selectively adjust the speed of, or the amount of resistance on, the one or more moveable members, and one or more processors. The one or more processors may be configured to receive a video workout program, execute the video workout program set to a first difficulty level, receive a second difficulty level, and execute the video workout program reset to the second difficulty level.

An exercise sensing method, an exercise sensing apparatus and an exercise sensing system are provided. The exercise sensing system includes a computing device, a storage device and at least one biophysical quantity sensor disposed on at least one muscle portion of a user. In the method, a current muscle strength of the muscle portion when the user performs an exercise is monitored by the biophysical quantity sensor. An exercise history of the user is accessed to obtain a muscle strength reference value of the muscle portion when the user previously performed the exercise. The current muscle strength is compared with the muscle strength reference value so as to adjust an exercise intensity of the exercise.

A bicycle trainer including folding legs and a vertically adjustable frame member supporting an axle and cassette where a rider mounts the rear frame, such as dropouts, of a conventional bicycle with the rear wheel removed. The trainer includes a flywheel with a magnetic brake assembly controlled through an open protocol and configured to receive wireless transmitted signals from an app running on a smart phone or other such applications. The flywheel assembly also includes a bracket coupling the magnetic brake with a frame. A strain gauge is mounted on the bracket to detect torque, which is used to calculate a rider's power while using the trainer.

An exercise system may include a stationary bicycle, a free weight cradle incorporated into the stationary bicycle, pedals incorporated into the stationary bicycle, a display, one or more processors, and memory. The memory may store programmed instructions of the programmed workout that, when executed by the one or more processors, cause the one or more processors to: automatically alternate, by the programmed instructions of the programmed workout, between biking portions of the programmed workout and lifting portions of the programmed workout; automatically control, by the programmed instructions of the programmed workout, a resistance level of the pedals during the biking portions of the programmed workout; and automatically present, by the programmed instructions of the programmed workout, lifting instructions on the display, the lifting instructions configured to instruct a user on lifting one or more free weights during the lifting portions of the programmed workout.

A system to determine and dictate individual exercise thresholds to maximize desired neurological responses.

A basketball training apparatus includes a shot completion sensor, a condition sensor, and a computer. The shot completion sensor determines whether a shot goes through a basketball hoop. The condition sensor senses a physical condition of a basketball shooter. The computer is in communication with the shot completion sensor and the condition sensor, and has a processor for calculating shot completion percentage as a function of the physical condition.

Systems and methods for controlling application of horizontal resistive force to a user walking on a treadmill to provide substantially constant force even if the user changes his or her relative position on the treadmill. The systems and methods can improve the user experience when force is applied while also improving user safety. The system has a cable, a motor, and a system controller. The cable can be coupled to a harness to apply a horizontal resistive force to a treadmill user, and the motor can be coupled to the cable and configured to apply a motor force to the cable. The cable can have an adjustable operative length. The system controller can have a processor communicatively coupled to the motor and configured to adjust the force applied by the motor in response to changes in cable length and a measurement of the actual force applied by the cable.
