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.

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.

An improved exercise equipment including a stationary exercise apparatus, a lever arm pivotably biased about a pivot axis, and a support for supporting the lever arm above the stationary exercise apparatus. The pivot axis extends substantially in a vertical direction. The stationary exercise apparatus is of a type to cause the legs of a user to scissor as the user operates the stationary exercise apparatus. In an exemplary embodiment, the stationary exercise apparatus is one of a treadmill, a stationary bicycle, and a stair climber.

An elliptical system is disclosed having a crank assembly configured to be adjusted in length to accommodate users having varying gaits. In some embodiments, the crank assembly includes a crank and an axle connection bracket that is slidably adjustable with respect to the crank. For example, the crank assembly can include a crank link having a longitudinal body, where the longitudinal body is connected to the crank at one end and includes a longitudinal slot slidably coupled with the axle connection bracket. The axle connection bracket is configured to slide through a plurality of positions along the longitudinal body. In some embodiments, the crank assembly further includes a screw for adjusting the axle connection bracket with respect to the crank, where the screw can cause the axle connection bracket to slide through one or more positions of the plurality of positions when the screw is turned.

The present invention provides a plurality of training modes for an electric walking rehabilitative device, including: constant speed mode, adaptive speed mode, strengthening push/pull mode, weight bearing mode, high frequency disturbance random speed mode, low frequency perturbation variable speed mode, direction control by handle push/pull forces mode, and slope mode, to improve the user's walking speed, muscle strength, balance, speed adjustment, direction control and slope walking.

A first determination that a range of motion of a user of an exercise machine is between pre-determined motion thresholds is made. While the range of motion of the user is between the pre-determined motion thresholds, a velocity of the cable being below a pre-determined velocity threshold is determined. In response to determining that the velocity of the cable being below the pre-determined velocity threshold while the range of motion of the user is between the pre-determined motion thresholds, a second determination that the user should be spotted is made, Torque of a motor is reduced based at least in part on the second determination that the user should be spotted.

An exercise apparatus including a stationary exercise apparatus and a lever arm pivotably biased about a pivot axis. A support supports the lever arm above the stationary exercise apparatus, and a biasing device rotatably biases the lever arm with respect to the support about the pivot axis. The pivot axis extends substantially in a vertical direction, and the stationary exercise apparatus is a treadmill.

An exercise system includes an integrated controller to automatically vary a resistive force output by the equipment during exercise in response to a user's characteristics. The user's characteristics are input to the controller, and the controller outputs signals to the exercise equipment corresponding to a workout regime. The exercise equipment includes a support system with an actuator assembly coupled to the support system and in communication with the controller. A resistance assembly is coupled to the support system and configured to translate along guides of the support system. The controller sends signals to the actuator assembly to vary a resistive force applied to the resistance assembly in response to the predetermined workout regime based on the user's characteristics.

An abdominal exercise roller with a powered wheel mechanism to assist the user during the abdominal exercise routine. The invention includes utilizing sensing technology and the electronic module to control the motor and optimize the performance of the abdominal roller during the exercise routine.

An ambulation simulating apparatus, including: a user feet interface comprising foot rests; a dynamic inertia mechanism configured to provide an inertial load when a downwardly force is applied due to the foot and a kinematic connection configured to enable transmission of motion from the feet interface to the dynamic inertia and backwards as the dynamic inertia mechanism resists said downwardly applied force by the foot.
