BOSU Ballast Ball

New weighted stability ball! This stability ball has 2-1/2 lbs. of unstable weight inside it, so it doesn't roll away when you're exercising. You can perform traditional stability ball exercises plus design new exercise sequences. It's a total-body training tool that's more versatile and easier to use than a traditional stability ball. Customize the size by inflating to 55 cm or 65 cm. 6 unique designs on the ball's surface provide points of reference for exercise techniques and cuing. Lift it, shift it, shake it-together the ball and the weighted material create dynamic resistance and audible feedback. You can even use it like a medicine ball. Includes foot pump and workout DVD. Translucent blue. 3 lbs.
