STOTT PILATES Mini Stability Ball, Red, 5"/13cm

Only writing this because people have been struggling to inflate this thing. This is not the only way I'm sure but it works reliably for me:1) You don't want the ball wandering off so I get on the floor and once the ball is half-inflated put it between the knees and keep inflating.2) You need to slightly over-inflate because a bit of air will escape as you...3) With your fingers of both hands very near the ball's hole, smoothly remove the pump and place a finger over the hole... all in one smooth movement. But you've got the ball between your knees so it's not going anywhere.4) Slide the stopper in under the finger you've got over the hole.I appreciate a video would be worth a thousand words so maybe I'll try that.Hope that helps.

I am trying to make my own p.ball, this ball is the perfect size and would be perfect in every way if they could fix the inflation issue. I was unable to use the straw to blow it up, as soon as I removed it, it would deflate. Frustrating and something they NEED to address. They have instructions on their website for how to inflate the ball. You need lungs of steel to be able to blow it up enough that is doesn't end up with creases from under inflation, but necessity is the mother of invention and I intended to make it work.I ended up taking a small strip of duct tape to cover the hole and used a pump that I had from another stability ball that I have. I was able to pump it up enough with the duct tape, and I was able to use the tip of the pump along with the tape to hold the air in long enough to get the plug in.

It came with an inflating tube to inflate the ball which was fine. The difficulty was when you tried to remove the inflating tube and put the plug in t was impossible to keep the full amount of air in the ball . After several attempts I quite and put the ball aside as in that state I was not able to use it for the purpose intended. Wouldn't but that type again

I had high hopes for this ball because I wanted a 5" one and was having trouble finding it. Instead of an inflation system where you stick the pin in the ball and inflate, you get a straw and a pin. You have to blow the ball up with the straw, quickly put your finger over the hole while you pull the straw out and then quickly remove your finger while sticking the plug in the hole. You have to be really quick. I spent way too much time trying to inflate this ball. I'll use it for now but will keep looking.

Blowing it up using the straw and then trying to plug it is difficult as the loss of air is inevitable. This ball size is hard to find so I’m glad I found it on Amazon. I actually needed a ball that is one inch larger than this one but it’s working out fine for my exercise routine… seems sturdy and well made so far!
