Product description

The Powerball – for unique and effective hand training
The powerball is a gyroscopic hand trainer which works without any batteries using the gyroscopic force: the ball rotates using muscle strength. This means that the ball always adapts to suit your level of ability. With practice you can reach up to 16,000 rotations per minute. Depending on how you hold the hand trainer, you can strengthen different muscles. The Powerball Auto Start is also fitted with a rotor which allows it to be started easily without a power supply. Even beginners won't find it too difficult at the start.

Product information:
  • approx. 250 g
  • Plastic, rubber edges
  • ø approx. 7.5 cm
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.

Be impressed by this effective hand trainer and enjoy the feeling – order the Powerball from Sport-Thieme now.

I've got it under control

Takes a bit of getting used to at first, but once you’ve got the hang of it, it’s a workout that’s highly addictive. Improves flexibility and strength, and you can take it with you anywhere. Great fun

Good for the wrist

The Powerball requires some practice and at least I had to read through the instructions, otherwise it fulfils its purpose. It takes some practice to exercise effectively.

Powerball

I tried the Powerball. My physiotherapist recommended it to me. It took me a while to get the hang of it. As soon as I had mastered the rotation, I could let the Powerball rotate endlessly. At some point my wrist got tired. I now train with the Powerball every day
