Welcome
to the new school stability ball training. The Ballast™ Ball
stays put. Because of this feature, your ball will no longer
wander around the gym. You can easily stack multiple
Ballast™ Balls on top of each other, so gone are the days of
unsightly storage contraptions. As if that wasn’t good
enough, the Ballast™ Ball opens the door to exercise
progressions and dynamic drills that you simply can’t
perform on a regular ball.
