NSD Roll’n Spin / Auto-Start Spinner
Have fun strengthening hands, wrists and forearms in just a minute a day

NSD Spinner will give your hands, wrists and forearms a workout with resistance training. It can develop and shape your grip and forearm muscles to improve baseball, tennis, golf games and most sports. Burn fat and get rid of flabby arms. It may help prevent and relieve repetitive stress induced injuries like carpel tunnel syndrome, tendonitis and RSI. NSD Spinner is a compact, simple way to isolation exercise without having to go to the gym. Lightweight, portable and perfect for traveling. It’s a great gift for anyone with no time to work out.

Roll’n Spin

No starter cord or external battery powered aid needed. We’ve made using the Spinner to strengthen your wrist and arms easier than EVER. The Roll ‘n Spin Spinner incorporates a pre-tensioner inside the gyroscope that allows for a simple roll back to spin up the gyro with enough momentum to get you started. Watch the attached video above to see how easy it is to get “started” exercising with the NSD Spinner.

Easy to Use

Our Spinners are a quick and effective way to increase your grip strength and an excellent complement to those who play sports. Professionals and amateurs alike can all benefit from our “One minute, One powerful hand” pledge! The instructions below apply to all the other NSD Spinner Roll’n Spin / Auto-Start models.

Wind-up the rotor first

Start the Rotor

Step One: Start

Wind-up the Spinner by turning the rotor in the direction of the arrow. Alternate the left and right thumb while maintaining pressure on the rotor. You should feel some resistance building up as you wind up the rotor, like a toy race car. The rotor should be fully wound within 10-15 steps.

Operate the Spinner like this

Operation Tips

Imagine there is a center point on the back of your hand. Make a circle around the center point when you hold the Spinner. The motion of your hand rotating the Spinner is similar to making ice cubes swirl inside a glass. The essence of operating the Spinner is not about how fast you rotate your wrist. It’s about how to synchronize your wrist rotation to the momentum and timing the rhythm of the rotor’s gyration. The faster the rotor spins, the easier it is to operate. Make sure you wind up the Spinner with sufficient tension.

Release the rotor and let it spin

Step Three: Rotate

Transfer the Spinner to your preferred hand. Rotate your wrist in a circular motion to speed up the gyroscopic rotor. Start your wrist rotation slowly. Increase your wrist rotation gradually. Be sure to keep a tight grip on the ergonomic grip once the rotor is spinning up to speed. When speed increases, the resistance increases.
