⭐ PORTABLE FITNESS TOOL — The Wrist Ball Trainer might just be the smallest, most effective fitness tool in the market today! It does not use batteries and any power source. It has no electromagnetic radiation. It stimulates the natural induced magnetic field and magnetic force generated by the operation of the celestial body. The faster the rotation, the stronger the kinetic energy and the greater the strength, which is equivalent to dumbbells of different weights.
⭐ MUSCLE TRAINING — The Wrist Ball Trainer provides resistance training to your hands, wrists, and arms. It may help prevent and relieve repetitive stress-induced injuries like carpal tunnel syndrome, tendonitis, and RSI. Adjust the angle of rotating the ball to target different muscle groups.
⭐ LED LIGHTS — When you spin the ball, its built-in self-powered LED lights will illuminate!
⭐ LIGHTWEIGHT — Put it at your desk, in your gym bag, or take it with you anywhere and spin your way to a healthy lifestyle!
