Powerball is a handheld gyroscope ball that is roughly the same size as a Baseball or Tennis Ball, being 7cm in diameter and weighing about 0.26 kg. The “ball” consists of a plastic outer casing, often with a rubber grip around the middle. Contained within there is a finely engineered and precision crafted gyro with a rotor that rotates swiftly once the ball has been initialized either by a rip cord or electronic starter. The fundamental theory revolves around how gyros act on the environment around them. Once started, the gyro will wield inertia and centrifugal forces on any objects it is in contact with. If a tipping action is applied to the gyroscope whilst it is rotating, then this will cause it to precess and move in a more circular fashion. The inside of the gadget is grooved near the axle, so with an exterior applied force, the axle will press against the rim. The gyro will react with a rolling action and the speed of the spinning will increase. You use your wrist in a spherical gesture to generate the force to continually increase the speed, which in turn acts with a greater resistive force upon your body.
The Powerball (or hand held gyro) is a truly dynamic object, there are no batteries and no electricity used, unless you have a type with a revolutions per minute counter. Applying the theory above, you turn the powerball with a circular wrist motion in either a clockwise or anticlockwise manner, it’s works in both directions. As you slowly build up the speed, calculated in revolutions per minute (rpm) the larger the torsion and dynamic forces acting on your wrist, lower and upper arm muscles, depending on the arm orientation and direction of motion. You can generate speeds in excess of 15,000 rpm’s with repeated use.

Powerballs are fantastic for being used as successful non impact exercise devices, all you need are hands capable of grasping the device. Due to the dynamic nature of the device, the force achieved from the device is only ever as much as the individual using it. Consequently the device is useful for increasing finger, hand, wrist and arm power as well as increasing blood flow and ligament power. Powerballs have become a everyday sight for patients trying to rehabilitate from wrist and arm injuries or those trying to cope with Repetitive strain Injuries. It can used in a fitness way to build muscle and in a sporting way to build power for certain sports, for example golf, tennis, baseball or any sport that requires great grasp and strong arms. You can even use it for fun, having contests between friends, family or colleagues to see who can get the best score.
Hopefully it is now obvious that the Powerball is truly a dynamic device. The numerous benefits include the ability to boost muscle definition and power, especially around the fingers, hands, wrists and arms. They can be used as rehabilitation tools and assist with repetitive strain injury for the young to the old. Powerball’s are quickly acquiring a reputation as being cool, multi facetted exercise device that can be used by people from any walk of life and in a multitude of situations.
