Fitness balls in bright Rainbow® colors and 3 sizes help support class organization and encourage exercise mastery. A seamless, roto-molded vinyl skin is designed to allow air to escape slowly, rather than burst in the rare case the ball is punctured. Great for strength, balance, and stretching exercises, a tacky surface enhances control to give students confidence as they train.
Unparalleled Strength and Safety
Burst-resistant to 1,000 lb, but supportive of static loads of up to 2,200 lb, this is our strongest therapy ball. Rotomolded vinyl skin ensures prolonged deflation in the event of a puncture, eliminating fears of rapid deflation that can cause harm to a student. A tacky surface also prevents slipping and sliding, keeping students safely in place as they exercise and build skills. When fully inflated, movements done on a flat, indoor training surface are easily transferred onto the fitness ball with smart gradual progressions, lowering the risk of injury that may come with non-textured balls.
Ideal for Training
Made for balance and stability exercises, but applicable for strength and weight training as well, stability balls add dimension to workouts through instability. Students must focus on weight distribution, balance, and coordination as they leverage balls into their activity, activating and engaging core muscles with micro twitches as they adjust. A wide range of exercises can quickly be adapted to include fitness balls, including planks, sit-ups, and push-ups, as well as more advanced, anaerobic exercises such as bicep curl or shoulder press.
An assortment of Rainbow® colors helps students associate different exercises with each colored gym ball and helps instructors identify areas of opportunity for individual students when exercising. Stations can be quickly set up and circuits formed to give the entire class a full body workout as students move from ball to ball and complete the corresponding activity. Rainbow® packs provide 12 balls to bring classes together for group training.
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.
Each set includes a measuring tape, plug, plug puller, and inflation instructions. For best results, inflate Rainbow® UltraFit™ Pro Stability Balls in stages according to included inflation instructions.
