I purchased a 75cm ball but could only inflate it to 63.5cm. Does the ball need to stretch a bit before it can reach the 75cm size?

Yes. inflat to the max. wait a few days,use it, sit on it. In time it will stretch out. You feel the difference once it's stretched out.

I wondered that also, but went ahead and ordered it. It was not inflated when it arrived and is was probably about 5 inches or so. So it may mean that it will function as a ball from 7.8 to 14.5 inches. One we made small and the other we inflated to the 14 inches. My grandson plays with it a lot.

Mine measures a good 72 inches. We used an air compresser to inflate it, and I would like to inflate it more, just haven't gotten around to do it. My grandson was a little cautious. Sorry it took me so long to respond.

I have an 18 lb ball from a different brand & it is around 1- 1/2 times the size of my 8 lb Valeo ball. I'd say add an inch to the circumference for a couple more pounds added. I hope this helps. I do like the Valeo brand over all others. Very nice grip.

Depends on what you are using it for. The work out video is lifting and stretching mostly. 75 CM is almost 30 inches, I am 5'10 and use the ball to sit on like a chair sometimes. 75 CM is the largest of them

Justin, I have not measured. I have enough air in the ball to hold me up, so I can exercise. I had to fill twice. OK mine is also the same as yours. If you measure to the center of the ball it's 30". Does this help???

I have found that after a few weeks the ball needs to be re-inflated. The firmer the ball, the higher you will sit. Hope that helps!

I just opened mine. Make sure the pump pin is screwed on tightly and that you stick the pin halfway into the ball. I had air escaping and my husband made those two adjustments and my ball is firm and has retained its firmness.

If you look on bottom there is a hole that allows to inflate (like a basketball). I personally haven't inflated my set, but I think this should solve your problem. Before trying you might check the Yamuna website QA.

A red Isokinetics anti burst ball, 55, fits very snugly, makes it a little taller. Other colors of the same 55 size need to be pumped up bigger to make them firm enough.

If the ball has a small valve hole like a football, it will not work. The inflator comes with 2 size tips. Both are too large to inflate that body ball.

Mine was not inflated enough when I got it, however one could have played with it in a pinch

I think you have to exend yours out to make it tighter. I made mine pretty taut. First, unscrew it so that it'sabout 4-6' wider than the space, then compress it so that it fits in snugly.

Hi, this pump should inflate your soccer ball but you need a Sports Ball Air Inflator Needle. Just attach ball inflate needle to Schrader (Not presta )side of pump attachment as you would a tire with a Schrader valve. I tried a sports ball inflate pin with the Topeak Peakini II Mini Pump and there is no problem attaching and locking it in place. I did not have a soccer, football or basketball to pump up though! God Bless!

Hello - the balls do need to be inflated up to 1.45 pounds per square inch [psi]. Thanks!

Typically, individuals less than 4 feet, 6 inches require a 30 cm ball. You should choose a 45 cm ball if you are between 4 feet, 6 inches to 5 feet tall. From 5 feet to 5 feet, 5 inches, select a 55 cm ball. If you are between 5 feet, 6 inches and 6 feet, 2 inches, use a 65 cm ball. If your height exceeds 6 feet, 2 inches tall, opt for a 75 cm ball.

You will see on the instructions the "why" -- it doesn't fully inflate the first time -- you are just inflating it to a firm touch -- and you will wonder "why so small"? On the second time -- next day it will inflate much more -- and then needs one final step. There is a hand pump that comes with these exercise balls that you can use on the final time if you prefer.
