The Powerball with the gyroscopic effect
Rotating balls, also known as Powerballs work using the gyroscopic force. They consist of a rotor which is mounted to a lead within the outer shell. Twisting motions get the ball moving and angular momentum occurs about the axis. At the same time, the ball becomes stabilised by the speed of the rotation and the inertial moment itself. Twisting the hand trainer causes the rotational axis to be tipped and the rotor tries to realign itself again by moving back. This makes the rotor faster and faster. There are gyroscopic forces that the user works against. With both versions, you can strengthen your deep muscles, fingers, wrists, lower arms and upper arms. Also improves your blood circulation in your brain, your stamina, grip and coordination.
