Abstract

A progressive resistance exercising machine having a single, substantially vertical guide column adapted to guide a reciprocating member which is provided with a laterally outwardly extending lifting arm engageable by the trainee. Both the guide column and a weight selector bar to which the reciprocating member is connected extends through centrally disposed apertures formed in a plurality of weights positioned substantially directly below the selector bar. When the selector bar is selectively interconnected with one or more weights in the weight stack, a lifting force exerted on the lifting arm will cause the reciprocating member and the selector bar to move upwardly against the urging of the weights. As the reciprocating member is moved upwardly, the central guide column accomplishes the function of uniquely guiding the travel of both the reciprocating member and the selector bar as well as constraining the path of travel of the weights. The vertical starting height of lifting arm can be adjusted by interconnecting the reciprocating member with the selector bar at various vertically spaced apart connecting points along the selector bar.
