Assisted racking of digital resistance includes detecting a state of a cable. A motor is mechanically coupled to the cable to provide resistance during an exercise by tensioning the cable. It further includes determining completion of the exercise based at least in part on the detected state of the cable. It further includes selectively removing resistance from the cable based at least in part on the determination that the user has completed the exercise.

A hippotherapy device for supporting a rider comprises a rider mount, which includes ribs and a backbone, a support frame, a drivetrain, and an enclosure. The hippotherapy device is configured to mimic the back of a horse and its undulating motion while a horse is walking.

A resistance force is controlled such that a user's effort against the resistance force results in a first isokinetic seed movement, wherein the user is an exercise machine user using an exercise machine. The resistance force required to effect the first isokinetic seed movement is associated with a predetermined force-velocity profile. A strength determination of the user is made based at least in part on the required resistance force and the associated predetermined force-velocity profile.

A weight training apparatus using hydraulics or pneumatics for applying positive and negative resistance closer to a user's maximum capacity throughout a lift is provided. The weight training apparatus allows for weight training without weights. The weight training apparatus may provide a more effective and safer mechanism for training than conventional techniques.

A toe-tapping exercise machine includes: a foot rest part having a right foot rest adapted to seat a user's right foot thereon and a left foot rest adapted to seat the user's left foot thereon; and an operating part coupled to the foot rest part to allow toe portions of the foot rest part to tap each other, the operating part including: a driving motor for transferring rotating power; a right foot rest operator for receiving the rotating power from the driving motor to operate the right foot rest; and a left foot rest operator for receiving the rotating power from the driving motor to operate the left foot rest, the driving motor being disposed between the right foot rest operator and the left foot rest operator and having rotary shafts extended from both sides thereof.

A portable and kinetic motion resistance upper body invention that can be used for a variety of exercises. This invention combines dial tension adjustment clutch sheaves, a variable linear tract bearing and a one piece resistance shock-cord, together these core components achieve a unique minimal impact work-out. The multi-motion and changeable adjustments for this invention, result in a wide variety of muscular stimulation and therapeutic exercises that are non-existent in the fitness and health industry. The outcome of the mechanism can be customized for a particular sport requirement or physio and other therapeutic restorations, or even for case specific industrial and robotic counter-balancing controls. This invention is can also be used as a lift-assist device.

A resistance force is controlled such that a user's effort against the resistance force results in a first isokinetic seed movement, wherein the user is an exercise machine user using an exercise machine. The resistance force required to effect the first isokinetic seed movement is associated with a predetermined force-velocity profile. A strength determination of the user is made based at least in part on the required resistance force and the associated predetermined force-velocity profile.

The exercise machine with a variable resistance system includes a frame, an exercise implement movably connected to the frame, a main shaft rotatably connected to the frame, a main connector attached between the main shaft and the exercise implement, a plurality of resistance assemblies and a plurality of actuation assemblies adapted for selectively engaging or disengaging at least one of the plurality of resistance assemblies with respect to the main shaft. The plurality of resistance assemblies apply a total level of rotational resistance against the main shaft based on which of the plurality of resistance assemblies are engaged with the main shaft by the plurality of actuation assemblies.

An interactive exercise system with apparatus and methods to optimize muscle strength for rehabilitation, to improve or maintain fitness, and to enhance the performance of athletes. The system uses an electronically controlled linear actuator to generate resistance against the muscular force exerted by the user. The system includes sensors configured to detect acceleration, speed, velocity, position, direction of movement, duration, and the force applied by the user. A control system preferably continuously monitors the sensors, and instantaneously adjusts the adaptive actuator. This provides a proportional counterforce to the user force throughout the entire range-of-motion. A display panel allows the user to interact with the system in real-time. The objective of the user is to synchronize the exercise performance with a selected target goal, by correlating the user's movement relative to a position on a display panel.

A weight training apparatus using hydraulics or pneumatics for applying positive and negative resistance closer to a user's maximum capacity throughout a lift is provided. The apparatus allows for weight training without weights. The apparatus may provide a more effective and safer mechanism for training than conventional techniques. An aerobic apparatus using hydraulics or pneumatics for a more realistic feel is also provided. Methods of using the devices are also provided.
