Start the Rotor View larger ( https://images-na.ssl-images-.com/images/I/51Mt9uXJX1L.jpg ) 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. Operation Motion View larger ( https://images-na.ssl-images-.com/images/I/51HersboMmL.jpg ) 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. Hold and then Release View larger ( https://images-na.ssl-images-.com/images/I/51Im+cwM6GL.jpg ) Step Two: Release ----------------- 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.

It may improve flexibility, endurance, grip strength and coordination in your hands and wrists. Move your wrist gently when you use NSD Spinner to alleviate wrist and finger pain from tendonitis and RSI. Wrist Rotation View larger ( https://images-na.ssl-images-.com/images/I/51OGYaGH2hL.jpg ) 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. Speedometer SM-02 Track progress and results with a digital counter. -------------------------------------------------- All NSD Spinners are compatible with NSD LCD Display Speedometer SM-01 and SM-02. NSD Speedometer may be ordered separately and snapped on the top of NSD Spinners in a second.
