Set-up: Put a calf-raise block or step roughly 2-3 feet behind a stable object which you can easily grasp for support. With the balls of the foot on the block and the heels off, bend at the hips to grasp the support.
Movement: Rise up onto the balls of your feet, then descend until your heels are below parallel to your toes. Keep your trunk inclined forward throughout the movement, hinging at the hips and not flexing the lumbar spine.
Optional weighting: A weight belt may be added for extra resistance. Alternatively, if you're up to it, a training partner can sit at the top of your hips.
