ABSTRACT:
An exercise machine for assisting a user in performing chin-ups and dips includes a pair of handles attached to a frame and a kneeling platform operably connected to the frame by a four-bar linkage. The pair of handles may be a pair of chin-up handles attached to an upper portion of the frame or a pair of dip handles attached to a medial portion of the frame. The four-bar linkage moves the kneeling platform along an arcuate path of travel corresponding to the natural arcuate path of the center of gravity of the user during a chin-up or a dip so that the kneeling platform remains beneath the user's center of gravity during performance of a chin-up or a dip. The four-bar linkage also preferably maintains the kneeling platform in a horizontal orientation. A selectable number of weights urge the kneeling platform upward so that the user may lift his body with his arms while applying a force less than his own body weight.
