Lie face up on the bench with your shoulders against the pads and place the balls of your feet on the bottom edge of the foot platform about 4-6 inches apart. Straighten your legs to push the platform, and keep them straight throughout the movement.
Let the platform push your toes toward you until you feel a good stretch in your calves. Do not bounce the weight. Press your toes until your feet are fully extended.
Hold this position for a moment, and then return to the starting position.
