This collection of images demonstrates the effectiveness of the Powerball in physical training and exercises using different positions and motions.

NOTE: Left-arm examples. For the right-arm the direction of the 'wrist rotation' (red arrows) must be reversed.

LOWER ARM

The Powerball is a variable state device which means it can change, at your command, from, and anything in between, a gentle rehab instrument, to a screaming ball of jerks and twists as it delivers almost 10kilograms of force in literally every direction.

UPPER ARM

For gentle exercise, rehabilitation of injuries, and relief from ailments such as Arthritis, Carpal Tunnel Syndrome and Tennis Elbow (to name a few), the Powerball should be used at low speeds, about 2000 to 4000rpm in the beginning, and then as strength and confidence increase, progress into the 5000 to 6000rpm range.

SHOULDER

The Powerball begins to deliver some serious power between 8000 and 10000rpm, unbelievably smoothly and yet still fully controllable! When bringing the Powerball up to these speeds you hardly notice the immense grip you have on it because there is a lot more interesting stuff happening inside the Powerball, you can hear it, feel it, see it - a totally immersive experience that could easily leave you quite addicted!

HAND & WRIST

Most of these exercises take place simultaneously. By experimentation with these basic concepts you will find many more ways to combine and single out certain muscles or groups of muscles.

Once you've discovered the fundamentals of how the motion of your hand drives and controls the Powerball you'll realise that you can do so much more with it.

You'll have so much fun using this incredible device that you'll forget it's exercise, but if you're in it for setting a new world record then you will be truly amazed at how your hand strength and stamina improve as a result.

If you play a professional competitive sport that relies on hand strength then you'll be in for a treat. This little device will change your game, guaranteed you'll feel it working those important muscles on the first day of using it - within a week you'll feel (and see) a difference.
