Single-leg calf raises

Stand behind a chair, holding onto the chair. Lift the "good" foot off the floor so that you are standing on the injured leg. Slowly rise up and stand on the ball of the foot and toes. Hold for 5 seconds then slowly roll down onto the entire foot. Rest as needed. Repeat 10 to 15 times (one set). Increase the difficulty of this exercise by rising higher, holding longer, or moving up and down more quickly. Perform a total of 3 sets.
