An exercise apparatus has an auxiliary weight system which can be used with virtually any exercise machine irrespective of its stroke length and which is relatively free of resistance due to friction caused by the interaction of the weights and their guide rods. The exercise apparatus of the present invention includes: a frame; an exercise arm attached to and movable relative to the frame; a set of first weights, each of which is of a first magnitude; a first moving unit for moving at least one of the set of first weights along a first path; a set of second weights, each of which is of a second magnitude that differs from the first magnitude; a second moving unit for moving at least one of the set of second weights along a second path that is noncoincident with the first path; and an interconnecting assembly for interconnecting the first and second moving units with the exercise arm such that movement of the exercise arm draws at least one of the first set of weights and at least one of the second set of weights along, respectively, the first and second paths.

Auxiliary weight system for exercise apparatus

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.
