This invention offers a rowing machine's mechanical resistance device which comprises an electric motor or a solenoid, a programmable control means and a custom algorithm, controlling the programmable controls means. It eliminates the compromising effect of backlash between the rower's handle and the resistance imparting device. This backlash is present between the power and the idle phases of rowing strokes on all state of the art rowing machines comprising flywheels. Ultimately, this invention allows all rowers to improve their rowing form and avoid injury.

A fitness training apparatus comprising a controller configured to communicate instructions to a load generator to apply a selectively adjustable load to at least one retractable line provided in or on a base, the retractable line having a free end region, the at least one retractable line being extendible from a retracted state to an extended state upon application of a force to the free end region, wherein the load applied to the at least one retractable line acts against the force applied to the free end region. The controller is configured to perform operations comprising setting a target speed band for the at least one retractable line, receiving a speed of the at least one retractable line, and responsive to comparing the speed to the target speed band, modifying the selectively adjustable load to the at least one retractable line to maintain the target speed band.

A platform-based strength machine enables users to perform strength or lifting activities or exercises via moveable or configurable pull points. The strength machine can include tracks that facilitate the configuring of the positions of the pull points, handles that control operation of the strength machine and/or measure movements performed by a user, compact motors that facilitate various platform or load application configurations, safety systems for the strength machine, and other enhancements.

An exercise system includes an exercise machine and an exercise handle coupled to the exercise machine via a cable, the exercise handle comprising a set of sensors. The set of sensors is used to detect a location of a portion of a user's hand on the exercise handle.

A toe-tapping exercise machine comprises: 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 comprising: 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 system having networked exercise devices that can have a shared virtual exercise session for training, collaboration or competition. The exercise devices each have adjustable difficulty setting and a touch screen for displaying different virtual exercise sessions. The touch screen can display a representation, such as one or more avatars, that represent users of the exercise devices, and that have a virtual speed in proportion to exercise performance on the exercise devices. Dynamic adjustment can be made based on the collective performance of the exercise devices, to cause a same adjustment to a respective current difficulty setting of at least one, two or more exercise devices during the shared virtual exercise session. Virtual training can be provided by way of a chaser animation that chases the representation of the exercise devices, the chaser animation having a virtual speed in dependence of exercise performance of users of the exercise devices.

Systems and methods are disclosed for assisting body motion by attaching a plurality of rods to a body; sensing movement parameters with sensors coupled to the rods; transmitting the movement parameters to a wearable device and receiving actuation commands from the wearable device; and based on the received commands, actuating the rods with one or more actuators.

An exercise device system comprising a tower; a support structure inclinable at different angles relative to the tower; a movable user support platform movably associated with the support structure for movement relative to the support structure; a pulley system associated with the movable user support platform; a cable extending through the pulley system and including opposite ends; exercise device handles coupled to the opposite ends of the cable, whereby movement of the handles causes movement of the movable user support platform relative to the support structure.

A fitness device includes a housing, a driving motor mounted on the housing, a fitness pull rope connected to the driving motor, and a control system connected to the driving motor. The control system comprises a main controller, a power module, a communication module, a driving circuit and a sampling module, the power module is electrically connected to the main controller and the communication module, the communication module is electrically connected to the main controller, the sampling module is electrically connected to the driving motor and the main controller, and the driving circuit is electrically connected to the power module, the main controller and the driving motor. The fitness pull rope is arranged on the driving motor functioning as a full driver, and the control system is used for controlling the pull force of the driving motor, thereby realizing smart fitness.

A training apparatus having a progress indicator and unified base for different apparatus types, such as for an ergometer, speed bike, recumbent bike, home training bike, rowing apparatus, elliptical trainer, cross-trainer or treadmill. The fitness apparatus of every apparatus type is based on a structure which is unified in terms of technical design, according to which the frame or pedestal of the fitness apparatus has rollers which are arranged on the frame or pedestal such that a tilt-stable positioning of the frame with respect to the subsurface and a longitudinal displacement of the frame or of the frame together with the pedestal relative to the subsurface is enabled by means of an actuator depending on the measure of success of the user training.
