An offloading system for use with a treadmill includes an air chamber configured to be selectively inflated between a deflated condition and an inflated, operating condition, a user seal coupled to the air chamber and adapted to receive a user so that, in the operating condition, at least a portion of the user is received in the user seal and positioned within the air chamber, a pump operable to inflate the air chamber, and a controller configured to determine an occurrence of a loss of pressure in the air chamber and, in response to the occurrence, cause a reduction of speed of a running belt of the treadmill.

Exemplary arrangements provide leg training devices suitable for high intensity training of hip flexors while simultaneously training the extensors of hip and knee joints. The exemplary leg training devices include foot fixings which are permanent vertically movable components of the device, each of which are configured to releasably engage a foot of a user in operative engagement therewith while limiting the movement of the foot relative to the foot fixings. Each of the foot fixings is operatively connected to a suitable mechanism that provides a resistance force to vertical movement of the foot fixing by the user's leg. In exemplary arrangements the resistance force may be selectively variable with regard to the magnitude and/or point of application so as to provide the desired training regimen.

An exercise device is described which includes a platform having a first end and a second end opposite the first end; first and second wheels, wherein the first wheel is positioned proximate the first end and the second wheel is positioned proximate the second end and the first and second wheels are configured to roll across a surface as the exercise device is displaced along the surface; a first motor configured to apply a first torque to the first wheel where the magnitude of the first torque is related to the distance of the exercise device from a zero position and the direction of the first torque urges movement of the exercise device toward the zero position. Versions are also described with more wheels and more motors.

A device for training and rehabilitation of a limb is provided. The device provides a board with an ability to magnetically levitate a movement base above the board to allow for controlled movement of a limb or other body part of a user needing training and rehabilitation in various directions.

A weight training apparatus includes an electrical hoist and a cable coupled to the electrical hoist. A first end of the cable is coupled to the electrical hoist and a second end is configured to attach to a barbell assembly. A sensor is configured to output a signal indicative of a lift position of the barbell assembly. A controller is programmed to compare the lift position to an predetermined vertical locations and activate the electrical hoist to change the lift position of the barbell assembly based at least in part on at least one of the lift position or vertical lift velocity relative to the predetermined vertical locations.

A piece of exercise equipment particularly for improved strength training exercises. More particularly, the invention relates to equipment that allows the user to vary tension when performing different exercises. The present invention is specifically designed for improved exercise through the variability of a tension component for use in such exercises as the plank exercise, sit-ups, push-ups and supine pull-ups that includes a core support, a guide arm, a head support, and a foot support that work in conjunction to most optimally support the user. The core support, the head support and the foot support are all connected, supported, and elevated from the floor by a central support system.

A body weight support system includes a support track, a trolley, and a power rail. The support track has a first portion and a second portion. The trolley has a support assembly and a drive assembly. The support assembly is configured to support at least a portion of a body weight of a user. The drive assembly is configured to movably suspend the trolley from the first portion of the support track when the user moves along a first surface and is configured to movably suspend the trolley from the second portion of the support track when the user moves along a second surface separate from the first surface. The power rail is coupled to the support track and is configured to be in electrical contact with a portion of the trolley as the trolley moves along the first portion and the second portion of the support track.

A support platform for retaining a DAP system inflatable enclosure is provided that includes a top cover including a support surface defining a truncated access opening, a bottom cover including a panel, and a plurality of side covers each including a panel, in which the top, bottom and side covers are connected to form an airtight platform defining an interior for retaining an exercise device. A base opening of the enclosure can be secured at a perimeter region of the access opening above the exercise device. The platform further includes an exercise device upper interface for securing the support surface to an upper region of the exercise device, a lower interface for securing a lower region of the exercise device to the bottom cover or ground, and a blower interface for forming an airtight connection with a blower. The truncated access opening limits pneumatic forces secured by the exercise device.

A chin-up/pull-up exercise apparatus is disclosed. The exercise apparatus includes a frame, an overhead assist module, and a chin bar. The chin bar is connected to the frame. The overhead assist module includes a set of pulleys, a harness, and a cable spool connected to a motor. The set of pulleys, which is connected to the frame, is positioned vertically above the chin bar. A cable, which travels on the set of pulleys, is connected to the harness and the cable spool that can be rotated by the motor. The exercise machine enables real, full arm extension pull ups regardless of one's upper body strength with applications for physical therapy; physical exercise training; muscle, tendon, and joint rehabilitation; and upper and lower body strength building.

A holder for a wearable device such as an exercise assistance device where the holder may include: a main rod; a sliding rod capable of sliding with respect to the main rod; a gripper including a gripper base, which is connected to the sliding rod and can support an exercise assistance device, a gripper head, which is connected to the upper side of the gripper base and can face the rear surface of the exercise assistance device, and a gripper arm rotatably connected to the gripper head; and a control unit for controlling the operation of the gripper, wherein the gripper base rotates with respect to the sliding rod and tilts forward if the exercise assistance device is put on the gripper base, and the control unit can move the gripper arm so that at least a portion of the gripper arm can cover the front surface of the exercise assistance device.
