ABSTRACT:
A leg press machine has a movement arm mounted by parallel links for pivotal movement about a generally horizontal axis in opposition to one or more resistance weight stacks on opposite sides of the movement arm. The linkage is connected to a drive lever below the movement arm which in turn is connected to the bottom of a weight stack rod to raise the latter and associated weights as the movement arm is pivoted by the legs. The movement arm is stabilized by the linkage and a counterweight connected to the linkage.
