Raise yourself to a standing position and grasp the back of a chair. While doing so, bring your right leg behind you and press your heel against the ground. Feel the strain in your right calf as you bend your left knee towards the right. Once you have held for twenty to thirty seconds, return to the beginning position. Reiterate. Next, repeat the exercise on the opposite side, this time with your left leg behind you and your right knee bent.
