NSD Power Winner's Precision Sterling Spinner Gyroscopic Wrist and Forearm Exerciser with Digital Speedometer, and Heavyweight Zinc Rotor and Stainless Steel Shell

NEW! We’ve taken our pinnacle Sterling Spinner design and improved it! Upgraded rotor and track allows for a smaller form factor without sacrificing the smooth ope ration of the Metallic Spinners, while the solid zinc rotor is retained to provide maximum resistance training through built up angular momentum. The added counter keeps track of Current total revolutions, speed in RPM, Historical top speed in RPM and Physical strength index, which makes it perfect for athletes looking for the ultimate in grip and forearm strength, or muscle builders looking to target and sculpt muscles specifically in the forearm. Pair it with our PB-588HC Spinner to train for muscle strength AND improve fast twitch for optimum athletic performance. Check out the attached video above for a comparison.
