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.

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.

Operation Motion

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

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.

Wrist Rotation

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.
