How much air pressure should be in the ball? How do I know when there is enough air in it?

We just judged it by feel, nothing designated on the packaging. We started a little on the "squishy" side and added a bit more at a time until it felt right to our kids (but before it appeared in danger of bursting!)

It comes inflated but occasionally needs extra air, I am in Boulder at altitude so most of the time I have to check the air pressure in the ball and add or deflate a bit. Sam Iannetta

a little pump comes with it and by hand or foot you pump it up till firm...and you stick the plug that is removable back in it....very easy, completely user friendly....I've used my ball for years and rarely need to add air....it's the most fun exercise at home you can find!

The size of the ball doesn't matter. It is the size of the shaft on the ball. A 2" ball is just fine, just make sure the shaft is the correct size.

The ball is deflated inside of the box. There is a hand pump inside the box that you must use to inflate the ball

You have to fill the ball with air. I use a small air compressor attached to my cars dc plug. The more you fill the ball the larger it gets. We use them for acrobatics at our dance studio, it actually can get bigger then the specifications.

Yes you pump this ball up with your breath but it takes very little effort. The ball comes with a small tube that you breath air into.

it is made of plastic, it will feel sticky. pay attention to the exercise not the feel of the ball.

Hi Alison, The ball should have come with a plastic straw. Insert this into the ball and inflate by blowing by mouth. The ball doesn't have to be inflated beyond what you can do by mouth. Just be careful when you put the white plastic plug in the inflation hole to seal it. This is where you can loose some of your pressure. This may take a few tries until you get the technique. Be ready to cover the hole with your finger after taking the straw out. Take the straw out of the ball while you're still blowing into the ball. Good luck!!

To be honest. I have had this ball for about 6 months now and I haven't had to pump it up since I did it the very first time. Air leakage is not a problem.

Yes you need a source of compressed air. Uses, if I recall from college, Bernoulli's principal by creating low pressure from high speed air flow.

The recommended psi (pounds per square inch) should be on the side of the tire. If not, for a 16" tire you should inflate to between 30 and 40 psi. If no pressure gauge handy, just give it the old feel test. Inflate the tire until you get to the point where you press on the tire with your thumb and the tire barely indents. I hope this helps!

Hi Agustin, the bladder is deflated and you will have to inflate it. It is best not to put in more that 4 lbs. of air pressure.You will need a pump like those for basketballs or find someone with one. Good luck, it's a good speed bag. Gary

I bought a pump at Target used to blow up basketballs, etc. There is what I would call a stop valve at the end of the valve so make sure whatever pump you use, pushes past that stop valve or no air will go into the wedge. Hope this helps you !

I have a large exercise ball that is about 18-20" high (radius measurement) and it works great. I think it would be fine for anything that you really want to be careful about how much air you are adding- and not to overinflate the ball, like if you used a high powered home air compressor.

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.

Yes, but like any football, basketball, or soccer ball you need a pump to get it and keep it at the correct psi.
