2. Note: It is the rotation of the wrist joint, not the swing of the entire arm
3. Due to its purely mechanical design, there is no power supply, and continuous operation of the wrist training ball requires continuous rotation of the wrist.
4. When the wrist training ball is activated, it emits a cold light (only suitable for wrist power balls with built-in LED lights), brightening as the inner ball’s rotation speed increases, while making a pleasant sound
5. After the wrist training ball is activated, it becomes easy to control and the wrist can rotate freely (in different directions, irregularly). When the wrist needs vigorous exercise, simply accelerate the wrist in a circular motion or quickly flip it up and down.
