Unparalleled Strength and Safety

A European, roto-molded plastic shell eliminates weak points, allowing the stability ball to support up to 220 lb. A thicker material also promotes even air distribution within the ball, to prevent sagging or dimples that might disrupt exercise activities.

Ideal for Low-Impact Training

Stability balls require cooperation from multiple muscle groups simultaneously, making them great for total-body low-impact training. Whether you're looking to work your core, promote endurance, or improve balance and coordination, it's easy to seamlessly incorporate UltraFit Stability Balls to scale up your results.

Convenient Organization

Rainbow colors allow teachers to take advantage of color-coding to organize equipment, teams, or activities. Quickly set up colorful stations to promote class organization and participation. Large packs of 6 or 12 stability balls are designed to accommodate the whole class.

Balls are available in 3 sizes to accommodate users 5'0" to 6'7" tall. Choose the size(s) that best fits your class or program!

All sets and packs include measuring tape, plug, plug puller, and inflation instructions. For best results, inflate Ranbow UltraFit Stability Balls in stages according to included inflation instructions.
