The Gyrospin™ Arm Strength Wrist Ball is a self-starting hand strength ball rated 100kg, built for arm and wrist strength training. It runs on a silent centrifugal spin with a metal ball core inside, and it includes a wrist strap.
Once you get it moving, the ball keeps spinning on its own through centrifugal motion, and the metal core keeps that spin quiet instead of rattling. The wrist strap that comes with it lets you keep hold of the ball while it spins.
Why it works
Metal ball core adds weight to the centrifugal spin.
Silent design means it spins without loud noise.
Wrist strap is included so you can keep a grip on it while it runs.
