The processing device is configured to execute the instructions to receive sensor data from a sensor operatively coupled to an exercise machine, wherein the sensor data comprises one or more measurements; responsive to the one or more measurements, cause the avatar to change a position in the video game; compare the one or more measurements to a target threshold; determine whether the one or more measurement exceed the target threshold; and responsive to determining that the one or more measurements exceed the target threshold, cause the user interface to present a modification to the video game.

An exercise machine inclination device for providing variable exercise intensity on an exercise machine by inclining the exercise machine. The exercise machine inclination device generally includes a base adapted for being positioned upon a floor, a support structure adapted for supporting the exercise machine, a hinge pivotally connecting the base and the support structure and an actuator connected between the base and the support structure, wherein the actuator adjusts an angle of the support structure.

A folding exercise bike has handlebar telescoping members configured to support handlebars, seat telescoping members configured to support a seat, a lower frame member from which the seat telescoping members and the handlebar telescoping members extend, pedals having an attachment point above the lower frame member, a first pair of legs attached to one end of the lower frame member and a second pair of legs attached to another end of the lower frame member. Each leg of the first pair of legs extending at an oblique angle from the lower frame member in a deployed position configured to support the folding exercise bike on a surface and each leg of the second pair of legs extending from lower frame member at an oblique angle in the deployed position.

A muscle activity output system includes: a muscle activity database configured to hold movable part attitude information and muscle activity information in such a manner that the movable part attitude information and the muscle activity information are linked to each other; and a processor. The movable part attitude information indicates an attitude of a movable part of training equipment. The muscle activity information indicates a muscle activity of each of muscle sites of the exerciser. The processor is configured to acquire the movable part attitude information while the exerciser is moving the body along the trajectory, acquire current muscle activity information for each of the muscle sites based on current movable part attitude information of the training equipment and the muscle activity database, and output the current muscle activity information for each of the muscle sites.

A limb exercise machine includes a first transmission unit and a second transmission unit. A left-hand control member, as well as a right-foot control member, is connected to the first transmission unit. The left-hand control member and the right-foot control member are pulled by the first transmission unit to be moved synchronously. A right-hand control member, as well as a left-foot control member, is connected to the second transmission unit. The right-hand control member and the left-foot control member are pulled by the second transmission unit to be moved synchronously.

Provided is a resistance device of a fitness machine comprising a wind drag unit and a magnetic resistance unit. The wind drag unit includes an air volume adjusting disc. The magnetic resistance unit includes a guide rail disc, a metal ring sheet, at least one magnetic seat, and at least one guide post. The guide rail disc has a guide disc rail through which the guide post penetrates. The magnetic seat is used to generate magnetic resistance with the metal ring sheet, and the magnetic seat has a magnetic seat rail. The guide post is connected to the air volume adjusting disc, penetrates through the guide disc rail, and extends into the magnetic seat rail. The guide post moves in the magnetic seat rail with rotation of the air volume adjusting disc to drive the magnetic seat to pivotally rotate relative to the guide rail disc.

An exercise machine accessory is disclosed. In one embodiment, a resistance identifier is configured to identify resistance for an exercise machine associated with the exercise machine accessory, wherein the resistance identifier is coupled to the exercise machine. In one embodiment, a motion identifier is configured to identify exercise motion for a user of the exercise machine. In one embodiment, a communications module is configured to communicate with the user of the exercise machine, wherein the communications module is coupled to the resistance identifier and the motion identifier.

An electromechanical device for rehabilitation includes pedals coupled to radially-adjustable couplings, an electric motor coupled to the pedals via the radially-adjustable couplings, and a control system including a processing device operatively coupled to the electric motor. The processing device configured to, responsive to a first trigger condition occurring, control the electric motor to operate in a passive mode by independently driving the radially-adjustable couplings rotationally coupled to the pedals. The processing device also configured to, responsive to a second trigger condition occurring, control the electric motor to operate in an active-assisted mode by measuring revolutions per minute of the radially-adjustable couplings, and cause the electric motor to drive the radially-adjustable couplings when the measured revolutions per minute satisfy a threshold condition, and responsive to a third trigger condition occurring, control the electric motor to operate in a resistive mode by providing resistance to rotation of the radially-adjustable couplings.

Tri-Power Exercising device allows a rider to simultaneously, or on demand, exercise virtually all muscle groups in his lower and upper body. The device includes a bicycle frame, pedals, forearm bars, sliding seat, computer and electronic display recommending energy modulation amounts from various muscle groups to optimize physical performance on any given trek. Because riders can exercise virtually all muscle groups at once, they reduce their exercising time, continuously builds muscle tissue throughout their whole body, and exercises their cardiovascular and respiratory systems completely. Riders operate the device by rotating legs on the pedals, rotationally oscillating the forearm bars up and down with their arms and shoulders, and then use core muscles to pull and push the seat back and forth on the slider. Inverted racks, pinion gears, and one-way bearings turn this linear power from the oscillating forearm bars and sliding seat into torque that rotates the crank axle.
