ABSTRACT:
An exercise machine primarily used in exercising and strengthening muscles and ligaments not normally affected by the standard dynamic and/or isometric approaches. The machine causes the user to work against a centrifugally operated brake which increases the resistance to movement as the rate of movement increases. A horizontally disposed lever including a stirrup is rotated about a vertical shaft by the foot and leg of a user, and the shaft is functionally connected to a speed increasing mechanism and its rate of rotation is regulated by a centrifugal brake. The amount of effort being expanded to overcome the brake resistance is displayed by a simple linkage from the brake mechanism to an easily visible indicator.
