'Non Impact' - You have full control of the resistance it generates
This is the key to the concept behind the device and the main reason why it is master of so many talents: NSD Powerball is a completely non impact device which, despite being just the size of a tennis ball and weighing only a little more, has the ability to exert phenomenal pressure on the fingers, wrists, arms and shoulders of the user if activated correctly.
There is no motor inside - instead, you have a perfectly balanced rotor (flywheel) which generates inertia as it is spun. The speed of the rotor can range from around 2000 rpm, at which point NSD Powerball is generating about 0.5kg of resistance on the arm/wrist, up to in excess of 15,000rpm, at which speed your arm and wrist are being subjected to almost 18kg of resistance and are receiving a workout like no other you will have ever experienced!
