Abstract
An upper body exercise apparatus to assist an exerciser to do chin-ups and dips. The apparatus includes a frame having a base, a platform parallel to the base for the exerciser to stand on, and chin-up handles and dip handles extending from the frame. A motive device oscillates the platform vertically between a lower position and an upper position while maintaining the platform parallel to the base. Angular displacement of the platform is prevented by attaching the platform to a guide member which permits the platform to travel vertically along the device frameposts but does not permit the platform to travel horizontally relative to the frameposts. The guide members can comprise a set of rollers or collars. The system further includes a control and monitor whereby the force is controlled and the oscillation of the platform is monitored.
