Add stability and versatility to your workout routine with the Champion Sports Deluxe Ball Base. Designed to keep exercise balls securely in place, this base helps prevent rolling during workouts, balance training, or seated use. Open grooves allow resistance tubes or exercise bands to pass underneath the base, expanding exercise options for strength and conditioning routines. It can also be used to stabilize an exercise ball when used as an alternative office chair to help support posture and core engagement. The base accommodates exercise balls up to 25.5", making it a practical addition to home gyms, fitness studios, or office spaces.
