Build the desired muscles without much effort!
Gyroscope Powerball will give your hands, wrists and forearms a workout with resistance training. It can develop and shape your grip and forearm muscles to improve baseball, tennis, golf games and most sports.
Burn fat and get rid of flabby arms. It may help prevent and relieve repetitive stress induced injuries like carpel tunnel syndrome, tendonitis and RSI.
How it works:
The device consists of a tennis ball-sized plastic shell around a free-spinning mass, which is started with your thumbs. Increase the resistance of the gyroscope by rotating the device, the faster you spin, the more resistance.
Track your progress:
You can track your progress with the device by trying to beat the next color level. Pink is the hardest color to reach and represents a resistance of 62KG.
When the highest level of resistance is reached, the device will flash multiple times. This is a great way to have competition with friends!
No starter cord or external battery powered aid needed. We’ve made using the Powerball to strengthen your wrist and arms easier than EVER. The
Gyroscope Powerball incorporates a pre-tensioner inside the gyroscope that allows for a simple roll back to spin up the gyro with enough momentum to get you started!
