Product Description

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, even as the solid zinc rotor is retained to supply maximum resistance training through built up angular momentum. The added counter helps to keep track of Current total revolutions, speed in RPM, Historical top speed in RPM and Physical strength index, which makes it best possible for athletes in search of without equal in grip and forearm strength, or muscle builders taking a look to target and sculpt muscles specifically within the forearm. Pair it with our PB-588HC Spinner to train for muscle strength AND strengthen fast twitch for optimum athletic performance. Take a look at the attached video above for a comparison.
Solid ZINC rotor provides a whopping 41.3 lb-in of resistance at 10,000 RPM
