The Primal Strength Plate-Loading ISO Lever Machines have been engineered to work in the natural motion of the body in order to optimise the isolation of the intended muscle groups. The Machines converge and diverge in a natural, arcing motion, guaranteeing users the maximum muscle contraction whilst providing the optimum safety when training. ISO Lever Plate-Loaded Machines have many benefits, including: Maximum muscle-extension in a supported position Converging and diverging range of motion Safely isolates muscle groups whilst allowing maximum weights to be lifted Ensures a natural lifting motion The Alpha Commercial Fitness Elite ISO Seated Calf Machine provides users with a full range of motion to stretch and press their calf muscles.
