3, hold the ball single-hand (the bottom of the palm), Immediately rotate the wrist as the thumb releases the inner ball (using the wrist as a support point in a rapid, repetitive circular motion). When the inner ball spins faster and the bright lights come on (note: there are some options without LED lights), the wrist training ball has begun. If the startup fails, repeat the preceding steps

Cause of product startup failure: Incorrect way of pushing the inner ball with thumb: not pushing in the direction of the inner ball arrow or pushing times are not enough. Do not retreat. Push forward as far as possible until the inner ball is difficult to roll, but remember not to exert too much force to avoid damaging the inner ball spring
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.
Product startup failure cause :
1. thumb push inner ball is incorrect: not push in the direction of the inner ball arrow or push times are not enough.
2. Incorrect rotation: The wrist joint should be in a circular motion, not the entire arm swing

4. During transportation, individual product components may be damaged and unable to start.
