Six-Sided Stability. Built to Challenge.
The BOSU® Ballast® Ball is unlike any other ball in the gym. A six-sided surface design promotes proper alignment and positioning, while 2.5 lbs. of multi-dimensional internal ballast keeps the ball from wandering during your workout and delivers audible, visual feedback as you lift, shift, and shake. It opens the door to exercise progressions and dynamic drills that just aren't possible on a standard stability ball.
Key Features
Promotes proper body alignment and positioning through every rep.
Keeps the ball anchored and adds audible, visual feedback during dynamic drills.
Latex-free material rated to withstand up to 1,000 lbs. of pressure.
Backed by a 1-year limited warranty.
Description
Use the Ballast® Ball as you would a standard exercise ball, or bring it into slam, throw, and shift drills the way you would a slam ball — the internal ballast is what makes both possible from a single implement. It's a versatile addition to core training, balance work, strength routines, stretching, and rehab programming for home or commercial gym floors.
