How can you train muscle groups that are normally difficult to train? The muscles of your fingers, wrist and lower arm get a good workout with this Tunturi Magic Ball. Ideal if you are suffering from RSI or a mouse arm.
The Magic Ball gets its efficiency from the centrifugal force. That force is variable and automatically adjusts to your level of training. The core of the Magic Ball moves through rotation, for example the wrist. That rotation creates strength and you can feel that in your fingers, wrist and lower arm. Even your biceps, triceps and shoulders feel the impact of a Power Ball. It takes some time getting used to a wrist trainer, but once you get the hang of it the movement becomes smooth.
