Roller ball, hand, arm and shoulder trainer

How do you train muscle groups that are otherwise difficult to train? Give the muscles of your fingers, wrist, and forearm a workout with this Magic Ball. It's ideal if you suffer from a mouse arm or RSI. Without batteries, The Magic Ball derives its efficiency from centrifugal force. That power is variable and automatically adapts to your training level.

The core of the Magic Ball moves through rotation, for example, from the wrist. That rotation generates force, and you feel it in your fingers, wrist, and forearm. Even your biceps, triceps, and shoulders experience the effect of a Power Ball.

It takes some getting used to getting a wrist trainer moving, but once you get the hang of it, the movement comes naturally. The benefits of the Magic Ball

- Hand trainer modeled after NASA

- Generates forces up to 18 kg

- Training for mouse arm or RSI

It also trains difficult muscles. You can get started in no time with this Magic Ball !
