OPTP Franklin Air Ball - 9" Exercise Ball for Pilates & Core Strength - 1 Set, 1 Piece, Blue, PVC, Inflatable

This has turned out to be a really great purchase. I had used one in my weekly Pilates classes and felt that it would be good for my daily morning stretches at home. It's a great first activity to do, to decompress your spine and do some slow stretches with it under your pelvis. The ball comes with a little straw to blow it up but you really don't need it; you can blow it up by mouth directly. It's convenient enough to take along when traveling... just deflate, pack it flat into a suitcase, and inflate again. It's roughly 6" in diameter and about 22" in circumference when blown up with a bit of "give." Good quality. Initially it felt a little sticky to the touch but that vanished within a couple of days. Edit: July 2017. The ball has finally started to lose air to the point where I have to blow more air into it every week or 10 days. The pin is really falling apart and it's very difficult to take it out. So I got myself a new one -- same product.

Love these. I’ve used them in Pilates for years. The level of inflation is customizable and they are very high-quality. I’ve had some for more than 10 years and they’re still going strong.

Nice ball, very very difficult to inflate and with the ‘straw’! Overall, a kids play ball from the supermarket works just as well , and less expensive, without having to inflate and try to seal this one.

I got this per my physical therapist and it’s been amazing in helping me to core work and tabletop. I place it at my lower back and it has just the right amount of give. The ball comes in inflated so you will need a ball pump!

A little hard to blow up. It is tricky to pull tube out then put in plug. Otherwise it I’d easy to use.
