ProBody really thought of everything when designing their Pilates exercise ball. Made to support core strength, balance, back rehabilitation, and general toning of the upper body, the Pilates ball was designed with anti-burst material as well, so you never have to worry about it bursting and becoming unusable. If it does burst within the first 90 days, they guarantee all of your money back. Additionally, ProBody made this product free of harmful phthalates like DEHP, DBP, BBP, DINP, DIDP, and DNOP. If that wasn’t enough, it comes with a ball pump and access to exclusive exercise videos and content, so you never have to go it alone.
