• Lie on your back in a doorway, with one leg through the open door.
• Slide your leg up the wall to straighten your knee. You should feel a gentle stretch down the back of your leg. Hold the stretch for at least 15 to 30 seconds.
  • Do not arch your back.
  • Do not bend either knee.
  • Keep one heel touching the floor and the other heel touching the wall. Do not point your toes.
• Repeat with your other leg.
• Do 2 to 4 times for each leg.

If you do not have a place to do this exercise in a doorway, there is another way to do it:

• Lie on your back and bend the knee of the leg you want to stretch.
• Loop a towel under the ball and toes of that foot, and hold the ends of the towel in your hands.
• Straighten your knee and slowly pull back on the towel. You should feel a gentle stretch down the back of your leg. Hold the stretch for at least 15 to 30 seconds.
• Repeat with your other leg.
• Do 2 to 4 times for each leg.
