Step 1: Stand with your feet shoulder-width apart.
Step 2: Extend both arms out to the side at a 90-degree angle to your body.
Step 3: Move your arms in small, fast circles forward.
Step 4: Do as many rotations as you can and then reverse the motion, doing as many circles as you can in the reverse direction.
Step 5: Take a break and repeat two more times.
You'll feel this exercise in your shoulders and will be able to do more revolutions if you keep your abdominal muscles pulled in and tight.
