Weight lifting apparatus having increased force on the return stroke

摘要

A weight-lifting apparatus operable by a person for weight training. The apparatus has a frame; a plurality of weights mounted on said frame for generally vertical reciprocal movement from a rest position upwardly against gravity force to an upper position, and downwardly from said upper position under said gravity force to said rest position. The apparatus also has a structure for lifting said weights against said gravity force and lowering said weights under said gravity. A resisting force in addition to said gravity force on the weight is applied to said structure during at least a portion of said downward movement of said weights.
