Feature

●[Clockwork Optimization, More Fun]: The structure of the self-inspired bar has been optimized to make it smoother, quieter and more fun.
●[Mechanical force, no power supply]: the rotation of the wrist interacts with the inner rotating ball, and the generated centrifugal force maintains the high-speed rotation of the ball.
●[Variable Speed Lights]:When the inner speed of the wrist ball increases, the lights become dazzling. You can feel the colourful rhythm and increase the fun of fitness.
●[INCREDIBLE POWER]: With its zinc rotor, the Power Wrist Ball holds the power of a metal series model and can output massive 60 lbs of pure isometric resistance. Use the immense power of the hybrid at high speeds to build solid upper arm muscles and experience the ultimate grip.
●[A MUSCLE BURNING EXERCISE]: Rotate the gyroball at high speed and experience the ultimate upper body workout that quickly builds muscles in the forearms, shoulders, wrists and fingers for improved muscle performance and stronger grip
