Review on Extra Thick Exercise Ball For Workout Fitness Balance - Gruper Yoga Ball In 45-75Cm - Anti Burst Yoga Chair For Home And Office With Hand Pump & Workout Guide Access Included by Zachary Caldwell

Love these balls. I wish I had not followed the other comments that said buy a larger ball then suggested. It is larger then I really like but I have a couple balls so I have a variety to play with. I would say follow the instructions on which size you get and not the comments that they run small . mine did not. Very thick material, easy to pump up. Its a cheap pump but it does the job just fine.
