Hamstring stretch

The hamstrings are the muscles in the back of the thigh, just above the back of the knee. To stretch them, you will need a stable stool that does not roll (or a stair) that is about knee height. Place hands on hips. Place the right heel on top of the stool, keeping the leg straight. Bend the left leg and slowly lean forward until you feel a stretch in the back of the right leg. Hold for 10 seconds. Rest. Repeat 10 times, then switch legs and repeat 10 times with the left leg on the stool or stair.
