Stand facing a wall with your hands on it. Step your sore foot back, with your heel flat on the floor and your knee straight. Bend your front knee and lean gently towards the wall, until you feel a stretch in the calf of your back leg. Keep both feet pointing forwards. Hold, then relax. Do not bounce.
If an exercise hurts more than you expect, stop and contact your clinician.
