Lie on your back and bring your right thigh toward your chest. Now bend your right leg so your right heel is near the back of your right hip. Your left leg can be either straight or bent. Grab hold of your right foot with both hands. Contract the muscles on the back of your thigh (the hamstrings) so that your heel pulls toward the back of your hips. Keep contracting your hamstrings while using your hands to pull your heel upward, unbending and straightening your leg as you go.
Six to ten reps per side
