Abstract
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.
