HOW: Position the step against a wall. Place the balls of your feet on the edge of the step. Slightly bend your knees and raise your heels off of the ground. Your entire body should be going up with the heel raise. Hold onto the wall for balance. Push through all of your toes, especially your big toe. Slowly lower your heels back down to the ground.
FEEL: You should feel your calf muscles working.
COMPENSATION: Don’t straighten your knees. Keep your toes pointed forward as you perform the raise.
