The Donkey Calf is specific for complete training of the calves (triceps suralis) and particularly of the gastrocnemius.The donkey calf raise machine can help to simplify this exercise. First, load on a comfortable amount of weight. Then, step on the foot plate, hinge at the waist, and situate the upper pad on your lower back.From this position, contract your calves to lift up on your toes. Squeeze your calves hard at the top and slowly return to the starting position. Repeat!
