Review on Thick And Anti-Burst Exercise Ball With Quick Pump Included For Balance, Workout, Core Training, And Stability - Suitable For Gym, Office, And Indoor Use - EveryMile Yoga Ball (55-75Cm) by Mark Harris

The material used for this ball is too thin and stretchy offering men or bigger people no support. I am 250 lbs. and I had to pump this ball all the way up until it was about to pop to get any support from it. I would never feel safe using something that is on the verge of popping. Also when you pump it up a lot, it loses it roundness and become more oblong or shaped like an egg causing it to roll all over the place. Disappointing. Don't get suckered by the low price.
