Make Arm Great Once More. Fingers, wrists, hands, forearms, shoulders, and biceps are all strengthened, and it's also good for co-ordination and blood circulation.
Features
- Because the dominant hand/arm was able to maintain the gyro ball spinning so readily, it will aid in the development of fine motor skills in the non-dominant hand/arm.
- It's easy to get started with a pull-string.
Applications
- And with the flashing LED ball, all you have to do is increase the speed by rotating your wrist and keeping in sync with the ball's spinning.
- The silicone grip part is also quite useful for keeping the gyro ball from falling loose from your hand.
- If you're really worried, you can tie it to a wrist strap.
