Stand with your feet spread slightly wider than your shoulders, and bend your upper body forward without straining. Take care not to bend your knees.
Bend while stretching your legs and waist and try to touch the top of your left foot. Stretch the same way on the opposite side as well. If your hands do not reach your foot, touch your ankle or your knee.
While staying bent over, swing your upper body left and right like a pendulum and relax. Bend your elbows and let your arms dangle past your head.
