Although stability balls have been in use since the 1960s, their original intended application was as a back-care tool for physical and occupational therapy. As the benefits of these lightweight, portable, and relatively inexpensive tools became more widely known, their use crossed over into the fitness arena, where they quickly became popular for core conditioning and full-body training. SPRI was instrumental in helping elevate stability balls within the club/instructor market. Through working with some of the leading industry educators, 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 then went on to become one of the first to offer a true “slow-deflate” stability ball. This ensures maximum safety while sitting, lying, kneeling, or lifting light weights on the ball. SPRI works closely with its trusted manufacturing partner to make sure that all SPRI stability 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.
