The Force Plate Loaded Calf targets and isolates muscles in the foot and calf to develop explosive leg power and build stabilizer muscle strength to protect the ankle joints. The foot platform features textured, non-slip coating for stable foot positioning throughout your sets. For added safety, the weight lock lever keeps the weights in place when not in use. Precision pivot bearings provide smooth, natural reps so you only feel weight resistance, not machine resistance. Nickel-plated weight plate storage bars are designed to withstand corrosion, rust and heavy use.
