User Manual - How do I start my new Powerball?
- Insert an end of the cord into the hole in the rotor. Proceed to turn the rotor forward with your thumb while maintaining pressure on the cord between your other fingers to make sure there is no slack as it winds up around the rotor groove.
- When there are only about 3 inches of cord remaining stop winding and hold the ball into the palm of the hand that you are going to spin the Powerball with (usually right if right handed, left if left handed). The exposed rotor will be facing the ceiling at this stage.
- Take the cord and give it a quick, sharp tug out and downward (really let it rip here, don't be afraid of it!) If you have done this correctly, the rotor will now be spinning at between 2400 and 3000 RPM.
- Immediately turn your hand over (so that the exposed part of the ball is now facing the ground) and begin to rotate your wrist (not your arm) in a slow circular motion as if you were slowly stirring a large pot of soup with a long wooden spoon. It's important to stress that the proper motion to do this involves no movement of your arm - just the wrist joint.
- The secret to easy starting of the ball is to begin slowly - i.e., after giving the ball a good spin with the cord, begin your wrist movement in slow, wide lazy turns (about 1 turn per second). Do not start with fast, short wrist movements as you will be out of sync with the slow spinning rotor and will find it difficult to properly increase the speed. In this matter, you will hear the rotor 'slapping' noise in the sphere as it struggles to find momentum.
- As you slowly build up the rotor's speed, you will find that the pressure acting on your wrist and arm will increase proportionally as gyroscopic forces build within the Powerball. Respond by reducing the diameter or your turning circle and increasing the speed. The shorter the circle the wrist goes through in an effort to spin the ball, the faster you will dirge the rotor and, consequently the harder it will be to do!!

Warning: Do not exaggerate your training the first day. Your muscles are not used to this kind of exercise and too intense training will make your muscles sore. Give your arms the time to gain the needed strength.
