NSD Metallic Titan Spinner Gyro Ball – Grip Strengthener for Forearms, Wrist & Hands – String Start Design, Up to 15,000 RPM – Portable Wrist Trainer & Workout Equipment– For Desk Workers & Athletes

The Innovative Exercise Machine Will Allow You to Exercise and Workout Anywhere Don't let the small size fool you. Pick one up, spin it up to 10,000+ RPM and you'll be amazed by the amount of physical work required to keep it spinning at speed, using such a small compact motion. Go ahead, feel the burning forearm after a minute of use. Because the resistance is provided by angular momentum built up through a spinning mass, a few minutes a day on our Spinner can be equivalent to hours of full motion work with a dumbbell or a curl. For athletes, amateur and professional alike, strong grip and forearm provide the ultimate in power, speed, and control in just about everything you do. Be it golf, tennis, baseball or just about any sport that involves the use of hands and arms, using the NSD Spinner will allow you to hit it harder, hit it faster and hit it straighter. Besides the physical benefits, it is just downright Fun to play with. Challenge a friend. Challenge a co-worker. Or a family member. See who can make the Spinner spin faster or glow brighter. See who can keep their Spinner spinning longer. Or break it out during 'break time' at work as your co-workers gather to watch in awe. You can have fun while exercising, or exercise while you have fun.
