Abstract

An apparatus for carrying out flexion exercises of the calf muscles is disclosed. The present invention provides a calf and foot stretching apparatus wherein the ball, the arch, the plantar fascitis and the heel of the foot conform to a convex curve of a foot plate with a slip resistant surface. While providing for effective stretching, the device provides for performing stretching and exercising in a safe, controlled and comfortable manner due to the design of the apparatus. The curved foot plate is firmly attached to a sturdy and stable support structure that may have means for attaching to a floor. Furthermore, so as to assist in keeping one'"'"'s balance, the apparatus may have a vertical bar extending from the support structure to a height sufficient for one to hold onto while exercising.
