The Powerball can be used by anyone with hands big enough to grip it. You use your wrist in a circular motion to generate the force to continually increase the speed, which in turn acts with a greater resistive force against your body. You can even use it for fun, having competitions between friends, family or work mates to see who can get the highest score. As you gently build up the speed, measured in revolutions per minute (rpm) the greater the torsion and dynamic forces acting upon your wrist, lower and upper arm muscles, depending on the arm orientation and direction of spin. There are a number of different uses for the Powerball that result in effective non impact exercise and it can be used in a fitness way to build muscle or for exercise and in a multitude of uses for all people young to old. NSD Powerball is a dynamic handheld device. At higher speeds, the pulverising forces building from within its core are key to a powerful muscle building process in the forearms, triceps, biceps and shoulders, making it an ideal training product for all sports enthusiasts and body builders alike.
