Keiser A300 Seated Calf Model 2936
The A300 Seated Calf workout machine 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-leg power. The machine automatically pre-loads and adjusts for leg length. Unlike conventional machines that use iron, the A300 Seated Calf workout machine’s inertia design gives you a smooth resistance. The result is a workout unlike anything else on the market.
