NEW D'Addario Planet Waves PW-DFP-01 Dynaflex hand and arm exerciser

Perfect for anyone who uses their hands—from guitar hand conditioning to drummers and even massage therapists and typists—the hand-held exercise ball has an internal Gyro Roto and users can start the Dynaflex with either the ripcord or the automatic starter. Then simply move the ball in a back-and-forth motion to increase the speed of the Gyro. Working the Dynaflex all the way up to 13,000 RPM improves coordination and builds strength and endurance in the hands, wrist, and forearms.
