Description
This is a Powerball Hand Trainer, designed to train the muscles of the forearm and wrist.
No force is required—the wrist rotates in the center of the inner ball to generate centrifugal force, allowing it to spin at high speed.
An internal elastic self-starting device enables the ball to start instantly by pressing and releasing.
Multicolored lights add extra fun to the training.
Train hand and forearm strength while enhancing interest in exercise.
The Powerball comes with a safety strap, brand card, user manual, and gift box.
Please ensure not to touch the rotating part with your hands during training.

• Trains fingers, wrists, shoulders, forearms, and upper arms
• Engages deep muscles
• Relieves neck muscle tension
