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.
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.
Hold the Spinner in one hand with thumb firmly pressed on the rotor. Release thumb to release the rotor. The rotor should now spin at a moderate speed.
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.
No battery required! Your hand is the battery of this device. 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 start the Spinner with sufficient speed. You may find more instructional videos on YouTube by searching "NSD Spinner."
Just like riding a bike! The faster you spin the wheels, the easier it is to stay up because the wheels actually start to fight to stay in their original upright position. This same principal is used in NSD Spinner to create force against your hand as you move it. At 10,000 RPM you can generate up to 26.8 lb-in of torque - with the Essential models.
