The FitBALL Roller is an inflatable vinyl doo-hickey (that's a technical exercise term) which is a combination of an exercise ball and a foam roller. It's portable and easy to clean, which makes it a nice choice if you've been thinking about using a foam roller (those can get pretty dirty). It also has more give than a foam roller, which makes it more comfortable to use.

Versatile tool allows movement in two planes. Maximizes abdominal exercises to strengthen and tone obliques and core muscles. Adjustable firmness provides a stability challenge for kneeling, seated or lying exercises. Not designed for standing exercises. Instructional poster included. Color: Gray. Dimensions: 6" Diameter x 30" L. Wt. 3 lbs.
