  1. Stand with your hands together, arms extended directly in front of you. This will be your starting position.
  2. Keeping your arms straight, quickly move your arms back as far as possible and back in again, similar to an exaggerated clapping motion. Repeat 5-10 times, increasing speed as you do so.
