Love exercise equipment that's totally versatile? Your Tone It Up exercise ball (or Swiss ball), is perfect for crunches, the TIU Beach Ball workout, stretching, or even to replace your desk chair for core and stability training. This balance ball is 30" round and comes with the Tone It Up logo on it to show the world that you're part of the TIU team! The gym ball arrives deflated, but comes with a pump, so you can fill it up with air, sip on some pre workout for an energy boost, and get sweating right away! On recovery days, use the exercise ball as a yoga ball in conjunction with our resistance bands to gently stretch and relax away tension.
