NSD Powerball


Whether it’s because Powerball has helped to repair a broken wrist or cure a carpal tunnel injury, helped to add extra yards to a golf drive or power to a tennis serve, added dexterity to guitar or drum play, built a massive forearm or simply given rise to hours of fun between two (or ten) friends who wanted to see who could spin it faster, there are probably a million-and-one reasons why Powerball is so much more than a shiny, beautiful sphere that feels incredible to hold.


From the tips of the fingers, into the hand, through the wrist joint, up along the forearm into the bicep and culminating in the shoulder, there isn’t a single muscle or tendon in the arm that escapes the smooth but punishing inertial resistance generated by a fast spinning Powerball.
