The Powerball ...

... is a useful tool for strenghening arms, wrists and hands. He functions with a
sophisticated system of rotors inside a ball shaped chassis. The through a spinning
movement generated centrifugal forces have an instant training effect, though a
little practise is required to put that thing in motion. At first i used a ball equipped
with a chord, what proved to be inefficient. I swapped him for the auto-start
version, which works just fine. Especially people dealing with carpal tunnel syn-
drome should give it a try, however he is very much suited for everyone, who
wants a workout for his rather flimsy arms.
