Adjust seat and knee pad position for height. Load weight. Sit down on machine and place legs underneath pad with balls of feet in a close stance along the calf step. Holding handlebars for support, push up through balls of feet and unlock bar; raise your heels as high as possible.
Hold for one second and then lower to starting position. Repeat this movement for all reps then re-lock bar, dismount from calf step and exit machine.
