The Strength Ball is a gyroscopic exercise ball that helps build strength in your forearms and wrists.

The digital counter measures the speed of the gyroscope and displays the number of revolutions per minute (RPM), which is perfect for both measuring how much you have improved, and for setting the benchmark for your friends to try and beat.
