How to do heel raises:

Start with feet shoulder-width apart, arms at the sides and head facing forward. Your shoulders should be relaxed, and your abdominal muscles should be pulled in to protect your back. Lift your body weight up onto the balls of the feet and hold for a three-count. Return to flat feet. Perform three sets of 20 heel raises. A challenging variation of the heel raise involves hanging your heels off a step and then raising and lowering yourself through the repetitions.
