Calf extension training device
A calf extension training device which focuses training on the calf muscles is disclosed herein. The training device may comprise a frame, base, riser, sled, and one or more springs. The sled may comprise a sled frame and shoulder extensions, and is configured to move along the length of the frame while attached to one or more springs. Generally, the user stands on the riser leaving the user's heels unsupported while the user's shoulders are engaged by the shoulder extensions of the sled. The user may then lift and lower the sled using his or her calf muscles. This occurs by the user raising or lowering his or her body by extending and flexing the ankles. Resistance may be provided by one or more springs attached to the sled and the frame. The springs may provide variable resistance against the force of the user's calf muscles.
