Start by putting your shoulders comfortably in the shoulder pads and upper back against the padding. Place your feet approximately shoulder width apart in the centre of the angled platform. Standing with your legs almost fully extended, unlock the safety with your hands.
Slowly lower yourself down by bending your knees until they are bent at approximately 90 degrees, then push back up until your legs are almost fully extended. Engage your core to keep, your back and hips firmly against the padding. Ensure that your knees move in a consistent motion in line with your toes. Once you have completed the desired amount of repetitions, at the top of the final repetition engage the safeties, then slowly lower yourself down until the safeties catch.
When at the top of the movement don't lock your legs out fully and avoid having your knees cave inwards beyond your big toes.
