This exercise stretches the muscles in the back of your thighs.
Straighten your left leg in front of you with the back of your knee firmly on the floor and your toes pointed straight up. Bend your right leg so that the sole of the foot is touching the inside of the left knee.
Hold for 15 seconds.
Slowly bend forward from the hips, reaching with both hands toward your left foot until you feel a good stretch in the back of your thigh. Bend as far as you can without pain.
Hold this position for 15 seconds
Slowly return to the upright position and relax. Then switch and stretch the other thigh.
Put your right leg straight ahead with your knee flat on the floor and toes pointed up. Bend the left leg so that the sole of that foot is against the right knee. Hold for 15 seconds.
Then bend forward from the hips as far as you can without pain. Hold that stretch for 15 seconds. Then return to the resting position.
Repeat once more time on each side.
