Stability Balls

Stability balls have been in use for around 50 years, although their original intended application was as a back-care tool for physical and occupational therapy—users recovering from injury or surgery can improve joint mobility and muscle flexibility when they move on the balls in a static or assistive manner.

As these portable, lightweight, and relatively inexpensive tools gained in popularity, their use crossed over into the fitness arena, and they soon became popular for core conditioning and full-body training. Holding, rolling, tossing, catching, and/or bouncing a stability ball with the entire body in motion helps elevate the heart rate and burn calories. Moving on a balance ball in a dynamic manner with body weight, free weight, pulley weight, or rubber resistance tools helps increase strength; they can also be used as a less-stable bench to perform traditional dumbbell and barbell exercises.

And stability balls—also called balance balls, exercise balls, fitness balls, workout balls, or Xercise Balls—have remained popular over the years for their proven therapeutic and training benefits.

SPRI was instrumental in helping elevate stability balls within the club/instructor market. Through an association with the educational arm of Resist-A-Ball®, SPRI had the opportunity to really listen to instructors, learn how stability balls were being used, and develop ways to improve them—without compromising on quality.

SPRI became one of the first companies to develop a true “slow-deflate” stability ball. If and when SPRI stability balls are punctured or torn, they will hold their original shape, losing air slowly rather than bursting. This ensures maximum safety while sitting, lying, kneeling, or lifting weights on the ball (up to 300, 400, or 500 pounds, depending on the ball). SPRI works closely with its trusted manufacturing partner to make sure that all SPRI stability balls and balance balls are durable, are free of harmful phthalates, maintain their shape and feel, and provide a safe, slip-resistant texture.

Specialized stability balls are now available for every exercise level—for beginners and mid-level participants in semi-controlled environments, all the way up to the most advanced exercisers and the most demanding applications. Always choose the ball with the diameter that is recommended for your height, and never inflate a balance ball past the recommended limits.
