Powerball Hand und Armtrainer

A play of colors between red, red-blue, and blue provides you with visual feedback on your performance. At 1,000 revolutions per minute, the Powerball lights up red; between 4,000 and 7,500 revolutions per minute, a mix of red and blue lights appears; and above 7,500 revolutions per minute, the Powerball shines blue. Place your thumbs on the rotating body and wind the Powerball up to the stop, or set the rotating body on a tabletop and wind the Powerball like a wind-up toy, then release or lift it off the tabletop and start making circular motions. Regular use of the Powerball Basic is excellent training for the grip apparatus for athletes who rely on hand strength, as well as for musicians and individuals who work extensively with a keyboard. The training helps prevent discomforts such as carpal tunnel syndrome, RSI (Repetitive Strain Injury Syndrome), tennis and golfer's elbow, or tension in the arms, neck, and shoulders, while also increasing finger grip strength and coordination skills, and training the shoulders, forearms, and upper arms.
