Its only the size of a tennis ball, but set the internal rotor in motion and it will literally become like a tiny hurricane in your hand - exploding with mind numbing gyroscopic torque/inertia!

The ball comes alive with forces, furiously thrashing and jerking as your arm and wrist try to keep it in control, spinning it faster and faster until you have it up to over 9000rpm and it's exerting about 16kg of pressure on your limbs, thats the 75x of its weight in the state of rest - no batteries, just pure gyroscopic power - the fastest human propelled device ever created!

The Spin Ball has hit the fitness market with a fury and it's here to give you a full arm workout quite unlike any other you'll ever have experienced regardless of current fitness levels.

It's secret lies in the way it isometrically tests the muscle groups in the arms and shoulders - you can have the ability to curl the heaviest of dumbbell's down in the gym but take your Spin Ball up to 13000rpm for just 30-40 seconds and we absolutely guarantee a muscle burn of monumental proportions.
