ABSTRACT:
An exercise machine for use in exercising a user's calf muscles includes a frame having a ground-contacting support, first and second spaced-apart knee-engaging pads which are movable in a vertical plane, a seat, and springs resisting the upward movement of the pads. The pads are each located at the end of a lever arm which is rotatably mounted to the frame at an opposite end. The springs are mounted on slidable sleeves, allowing a user to adjust the resistive force. A handle engages each arm and is movable between a first position in which the arm is in a raised, locked position, to a second position in which the pad engages the knee of the exerciser. A user places the balls of his feet on a platform and presses the pads upwardly with his knees against the springs to exercise his calf muscles.
