1. Put a rope on your wrist to ensure safe use;

2. Use the thumbs of both hands to push the center of the ball in the direction of the arrow until the center of the ball cannot roll;

3. Quickly release the center of the ball with your thumb, and the center of the ball will gain an initial momentum;

4. The wrist exerts force along the inertial rolling direction of the center of the ball and gradually accelerates. If you feel that the force on the wrist is getting stronger and the light becomes brighter, it means that the force is exerted in the correct direction.

Features:

Exercise with powerball is completely equidistant, so it can complement any training method. Powerball exercises the arms in a way that conventional isotonic (free weight) exercise training cannot achieve, and it can absorb a higher percentage of muscle fibers in a shorter time. If you want to improve your wrist, grip and arm strength, then the wrist training ball will be your perfect choice!
