Rainbow® colors make class organization simple, with packs and colors to support entire classes as you get the most out of exercises and ball activities. A European construction and extremely durable design support up to 220 lb! Build core, lower-body, and upper-body muscle strength using a range of stability ball exercises, while also increasing balance and coordination. Exercises allow users to focus on abs, back, hips, and more, with low-impact.

Unparalleled Strength and Safety

A European, roto-molded plastic shell serves to eliminate any seams or potential weak areas in the design of the ball, to add strength up to 220 lb of support. For exceptional durability and maximum resilience it’s best to inflate, then re-inflate balls after a 24-hour period. A thicker ball material also promotes even air distribution within the ball, to prevent sagging or dimples that might disrupt exercise activities.

Ideal for Training

Stability and yoga ball exercises make it possible to activate entire muscle groups for targeted training across a student’s entire body. Squats and crunches work abs and core; leg raises and extensions promote lower-body endurance; push-ups and dips work arms and shoulders; and a range of balancing exercises serve to improve weight distribution and coordination skills across the board. A tremendous range of activities are possible with a Pilates ball, adding scalability and depth to bodyweight exercises. Low-impact motions are also healthier for joints.

Convenient Organization

Teachers can also use colors and sizes to quickly set up stations and relay activities to promote class organization and participation. When color coordination is linked to specific exercises, students will quickly recognize areas of improvement and practice accordingly. Group training is also made instantly possible thanks to Rainbow® 12 Packs and various ball sizes, designed to accommodate entire classes.

Available in 3 sizes to accommodate users 5'0" to 6'7" tall. Choose the size(s) that best fits your class or program! Includes measuring tape, plug, plug puller, and inflation instructions. For best results, inflate Rainbow® UltraFit™ Pro Stability Balls in stages according to included inflation instructions.
