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 support for the exerciser, and chin-up handles and dip handles extending from the frame. A motive device provides for movement of the support vertically between a lower position and an upper position. Angular displacement of the platform is prevented by coupling the platform to a guide device which constrains the support to travel along a predetermined path. The guide device can comprise a wheel and track system. Binding of the wheel and track system is avoided by providing a force to the wheel and track system which tends enhance tracking.
