Place cable belt or dip belt around waist. Kneel before low pulley and attach belt to cable. Stand on calf block and grasp support bar for balance. Position toes and balls of feet on calf block with arches and heels extending off.
Raise heels by extending ankles as high as possible. Lower heels by bending ankles until calves are stretched. Repeat.
Chain may be used to add length to cable so belt can be more easily attached to cable as long as it is short enough to allow full range of motion. Exercise step that will not overturn can be used as calf block. Keep knees straight throughout exercise or bend knees slightly only during stretch. Quadriceps serve as synergists muscle if knees are bent slightly during stretch. See Calf Exercise Analyses. Also see same movement performed on slightly different apparatus, Lever Standing Calf Raise (belt loaded).
