Can I use Powerball® in both hands?
Most people will have a dominant hand and this, by nature, usually tends to be the one which most often suffers from those repetitive strain injuries that Powerball® loves to rehabilitate.
Powerball is designed to spin in a clockwise or anticlockwise direction in either the left or right hand and this be altered while the rotor is stationary or spinning the only caveat is that you don’t switch rotor spin direction violently! (it will switch between a clockwise and anticlockwise spin in the blinking of an eye but doing so at high speeds can cause undue wear and stress on the rotor support band and is therefore best avoided!).
