ABSTRACT:
A frontal calf exercising machine which utilizes a frame-journaled rotating foot-engaging assembly to apply resistive force couples to the tops of an operator's feet and bottoms of his heels through circular paths about the axes of rotation of his ankle joints. This frame-journaled rotating foot-engaging assembly is mechanically linked to a frame-journaled rotating weight arm, which, together with the frame of the machine and the connecting link joining them, form a simple planar double-rocking-lever four-bar linkage which acts in conjunction with the rotating weight arm to vary the resistive force applied to the dorsi-flexing muscles of the operator's feet through body-machine contact between the operator's feet and the rotating foot-engaging assembly throughout the range of the exercise movement.
