300 Seated Calf
The A300 Seated Calf was originally designed for world record holders Willie Banks (triple jump) and Mike Powell (long jump). It features unilateral movement to help develop balanced explosive lower&8209;leg power. The machine automatically pre‑loads and adjusts for leg length. Unlike conventional machines that use iron, the A300 Seated Calf’s low‑inertia design gives you a smooth resistance. The result is a workout unlike anything else on the market.
