Hold the Powerball firmly and move your arm slightly away from your body. Rotate your wrist in a counterclockwise motion while keeping the rest of your arm still. Once you have completed the desired number of rotations, reverse the motion and rotate your wrist in a clockwise motion. This will target different forearm muscles.
Begin by curling your arm until your forearm is positioned at about a 90-degree angle relative to the biceps. Hold the Powerball firmly with your wrist angled slightly toward you, and rotate it in a counterclockwise motion.
Keep your arm straight and by your side as you hold the Powerball firmly. Rotate your wrist in a clockwise direction to target the deltoid.
Keep your arm to your side with just a slight bend in the elbow. Holding the Powerball, rotate it in a counterclockwise motion.
