This ultra simple exercise is performed by standing in front of a wall about a foot or so away, and with your hands on the wall in front of you and your knees straight, just extend your ankles so that you move onto the balls of your feet. This works the gatrocnemius muscle of the calf, with is part of the calf complex. To work the other part of the the calf, the soleus muscle, the knees need to be bent at an angle, preferably a 45 degree one. You can intensify this exercise by doing it on only one leg rather than both at the same time.
