The best products don’t require a lot of fuss, they just work. Wind back the precisely balanced zinc rotor; release and begin turning your wrist in slow, gentle circles.
As your Powerball® rotor builds speed so does the gyroscopic resistance created. This resistance is in the form of isometric exercise for a Powerball® user. Perfect for rehabilitation & strengthening from fingertip to shoulder.
SPEED = POWER
The faster you rotate your wrist, the faster the rotor spins and the more resistance Powerball generates..
From 1.0lb right up to 60lbs.
Spin slowly for rehab of RSI or a broken bone; spin fast to build gold standard grip and forearm strength
