The ProsourceFit Core Balance Disc is a fun, versatile tool for personal trainers, group fitness instructors, Pilates instructors, physical therapists, or anyone who wants to improve their balance and core strength. This lightweight, portable disc creates an unstable surface that can be used for a variety of purposes such as standing balance exercises, seated or kneeling Pilates core workouts, or prone movements like planks and push-ups. It can also be used as a seat cushion for both adults and children. One side features small bumps to provide traction and grip, while the other has more tactile, flexible raised bumps for a massaging effect. The disc may be used on either side, according to your preference. The stability disc is 14-inches in diameter and approximately 3-inches high, depending on how much you inflate it (not to exceed 5”). It comes with a hand pump so you can inflate it according to your needs and comfort level. Great to have on hand at gyms as well as at home for strengthening, balance and therapy exercises you can do anywhere. Comes in 6 colors.
