The fastest and most perfectly balanced hand gyro range on earth - capable of reaching speeds in excess of 15,000rpm all powered simply by your own hand!

Although only the size of a tennis ball, the Powerball has an amazing effect. Set it in motion with the cord provided, and the ball comes alive with gyroscopic forces! It's your job to calm it down using the strength in your arm and wrist – but it isn't easy. The Powerball thrashes and jerks in your hand, spinning faster and faster until it reaches almost 15,000rpm! (Revolutions per minute to the uninitiated.) Once you get to that stage, the ball is exerting about 40lbs of pressure on your arm, wrist and shoulder, and is travelling at nearly 250 revolutions per second! You can just imagine the effect this has on your muscles.

This superlative instrument comes complete with a digital speed meter to allow you monitor your power improvements on a daily basis and test your skills against both your friends and Powerballers throughout the globe on the Top 100 scoreboard! (batteries are already installed - approximate 3 year life span)

Everyone can benefit from the muscle-building effects of the Powerball. Its concentration on the arms, shoulders and wrists make it an ideal aid for virtually all athletic activities. Keen golfer you may find it particularly useful. Karl Woodward, World record holder for golf driving, is one of several pros to officially endorse the Powerball. He claims regular use of the Powerball added distance and stability to his golf drive – and if it can help the experts, imagine what it can do for a beginner.

Also included are full operating instructions, 2 starter cords and our unique lifetime warranty.

Instructions:

So just how does this wonder work? It's easy. Just insert the hard end of the cord into the hole – in the rotor of course! Turn the rotor forward with your thumb, keeping pressure on the cord between your other fingers to keep it tight as it winds around the rotor groove. When around 3 inches of cord are still poking out of the ball, stop winding and hold the ball with the rev counter in the palm of your hand. Keep the string facing upwards, then give the remaining 3 inches of cord a quick sharp tug downwards with your other hand.

The rotor should be spinning like mad by now. Keep turning your wrist – but NOT your arm – in a stirring motion. The pressure then increases as the gyroscopic forces begin acting on your arm and wrist. These forces slow you down – your job is to fight against it and get the speed up!

The Powerball is not only highly beneficial, but highly addictive. Once you've started spinning, you won't want to put it down. Your arms will feel like lead, and it's worth it.

Q. Does the Powerball increase your bicep muscle strength or is it only the wrist muscles?

A. Yes the Powerballs give some serious increase to the users' Biceps Muscle strength.

How it works is as follows:
Eventually due to the increase in speed from building the muscles on your wrists and fingers the vibrations travel the whole way up your arm on to your shoulders and neck muscles.
