Stand upright with your feet about shoulder-width apart. Position your arms straight out in front of you just below shoulder height. This is your starting position. Move your arms back as far as possible, keeping your arms straight, and back in again. This is like an exaggerated clapping motion and is done quickly. Repeat this motion 5-10 times, increasing the speed each time.
