ABSTRACT:
A device for exercising the calf muscles of a user including a frame formed of a base and two substantially parallel diagonal beams extending from either side of the base forming an acute angle with the base. A pad, contoured for accommodating a front side of at least one of the user's thighs is connected between the diagonal beams and extends at an angle adjustable within an obtuse angle supplementary with the acute angle. A weight bar is movable along the length of both diagonal beams and is releasably held at a plurality of different heights above the base. The machine is operable between a first secured mode securing the weight bar at a desired one of the plurality of different heights and a second released mode releasing the weight bar from its secured position. Connected to the weight bar is at least one foot pedal having an engagement side substantially facing the contoured pad, the angle of the contoured pad and the height of the weight bar are adjusted to accommodate the physical dimensions of the user wherein, when the machine is operating in the second in use mode, at least one of the user's associated thighs is accommodated by the contours of the contoured pad, the associated lower leg of the user extends at an angle substantially equal to that of the diagonal beams and at least one of the user's feet contact the foot pedal.
