Abstract:
1. An exercise machine comprising: a. a frame resting on a floor, wherein the frame comprises a pair of upstanding posts having respective lower ends that rest on the floor, and a stabilizer fixed to the posts and having an end that rests on the floor; b. at least one bearing on the frame that defines a pivotal axis, said at least one bearing comprises a bearing on each post; c. a leverage arm connected to said at least one bearing for pivoting about the pivotal axis, and for holding a first weight, the leverage arm having a spotter end at a first distance from the pivotal axis, and a force station at a second distance less than the first distance from the pivotal axis, wherein the ratio of the first distance to the second distance is approximately four to one; and d. a support attached to the frame at a predetermined location relative to the force station that enables a person to be supported on the support and to contact the force station with selected parts of the person such that exertion of selected muscles on the force station in a concentric function pivots the leverage arm in a first direction, and a small force applied to the leverage arm spotter end at the end of the concentric muscle function by the person causes the person to exert the selected muscles in an eccentric function and controllably pivot the leverage arm in a second direction.
