Build Strength & Endurance
Isometric training with Powerball is a highly efficient method of building muscle strength and endurance. Stronger muscles with greater endurance capacity mean you can work out harder for longer, and it reduces the risks of repetitive strain injuries on the forearms or wrists following long training sessions.
Pick up a Powerball and feel the power immediately.
Powerball is like a rapidly spinning vortex in your hand; the faster the engine spins, the more inertial resistance it generates, working your arm harder and harder until your muscles are burning and screaming for you to stop. And because it generates pure isometric resistance, Powerball engages almost the entire group of fibres in each muscle that it’s exercising, ensuring that you’ll reach fatigue in a much shorter time frame than with traditional exercise methods (less than 30 seconds in fact, if you really accelerate Powerball’s rotor speed).
Put down your dumbbells and take a fresh look at the way you exercise – these small balls really can build arms of steel.
