Gravity Drop

• Wearing rubber-soled shoes for traction (tennis shoes,
  etc.), hang your heels off a step or stairway with only
  the ball of each foot touching.
• Be sure both feet are pointing straight ahead and
  hip-width apart.
• With one hand or both, hold onto a railing for support.
• Let the weight of your body drop your heels off the stair.
  You will feel a great stretch in your low leg musculature.
• The key is to keep your hips over your heels and your
  shoulders in line with them also.
• Relax abdominals to breathe through belly.
• Hold this position for 3 minutes. (Check feet periodically).
