Reduced pressure, powerful performance, adopts mechanical power design, self-starting device, and variable-speed colorful lights. As the speed of the core increases, the color of the internal light-emitting strip will be more colorful, making the exercise more go away. Our wrist ball can adjust the weight manually, adjust the rhythm and speed of the core rotation, the faster the speed, the greater the force generated. This wrist force ball can effectively alleviate the soreness and strain of the musculoskeletal and other problems caused by long-term use of the wrist and arm, and can also help fitness enthusiasts to carry out targeted training. Our wrist force ball has a built-in automatic elastic device, which does not require a traditional drawstring to push it to the end along the arrow, and it can be easily opened by letting go of the ball core. With the faster the rotation, the stronger the force, and vice versa, the internal self-inspired strip structure optimization runs smoother, the noise is lower, and the play is more enjoyable.
