How & When To Use
After getting the inner section moving with the starting cord, hold the ball in your hand and make circular movements with your wrist. Keep moving like this and increase the rotation. Centrifugal force means it gets harder and harder to keep up the speed the faster it rotates.
It can reach speeds of around 15,000 rpm, and you'll have to handle some real forces when you start to get near those levels!
It can generate up to 15kg of inertial resistance for powerful upper arm muscles and a strong, solid grip!
