This exercise helps stretch one of the calf muscles called the gastrocnemius. Line yourself up squarely in front of a solid wall. Outstretch your arms to lean against the wall. Move one foot forward. The other foot should stay back. Straighten the knee (on the leg that is further back) until you feel a stretch in the back of your calf. Hold that position for 30 seconds. Start out doing 3 sets of 10 exercises and work your way up to doing 3 sets of 30 exercises. Try to do the exercises three times per day.
