HOW: Place an elevated surface next to a wall. Stand on the surface and use the wall for support. Straighten one leg as you keep your toes on the surface and let your heel drop to the ground creating a stretch in that calf. Hold that stretch for as long as prescribed.
FEEL: You should feel a stretch in your calf.
COMPENSATION: Keep your knee straight as you stretch. Keep your toes on the surface to create the best stretch.
