You set this 'engine' in motion using a cord, or with a quick flick of your finger, and then build its speed by subtle rotation of the wrist. Powerball contains no motor or batteries. It is driven by pure muscle power and all of its speed and energy comes from your arm, wrist and hand and, the stronger those wrists and forearms are, the faster you’ll be able to make your Powerball spin. And the faster you spin that inner ‘engine’ the more inertial resistance it generates and the more force it subsequently inflicts upon your fingers, hands, wrists, arms and shoulders as it ‘fights’ back against your efforts, ultimately making your wrists and arms even stronger in the process.
