Stand with one knee bent and the other leg straight out in front. Point your toes towards your body and lean forward. Keep your back straight and rest your hands on your bent knee. Make sure your toes are pointing upward. Letting your toes point to one side will cause this stretch to put uneven tension on the calf muscles. Over an extended period of time, this could lead to a muscle imbalance. Hold the stretch position for a minimum of 20 seconds and then repeat with the opposite leg.
