Celsius Anti-Burst Fitness Gym Ball Questions & Answers

I recently bought a 75cm ball, when I got it out of the package, it looked to small. I inflated it using an electric camping pump. Once it got what I felt was full size, I then measured it from floor to top of ball which was approximately 60cm. I was doubtful that it would get up to 75cm so I took it back to where I bought it. The person there said it would eventually reach 75. I don't think that is right. So 2 questions 1- does a 75cm ball start out really small and grow up to 20? 2- can a 65cm ball expand to 75cm

Hi, I recently purchased an anti burst Celsius ball, have had it for three maybe four months, today it burst, did I pump it up to much?

Hi there! Just wanted to ask what the safe working weight range recommendation would be for this product and the Celsius balance trainer. Many thanks
