BOSU® Ballast™ Ball
Welcome to the new school stability ball training by BOSU®. 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.
