Humactive 10" Mini-Fitness Balls for Pilates, Yoga, and Exercise Training

This ball is about the size of a volleyball. Several cons and one big pro:Cons:It's not very round--somewhat egg-shaped.It comes deflated and folded, so there are two weak points in the material at both ends of the fold. If this ball were ever to burst, this is where it would happen, but I don't think it will come to that.It comes with a short straw to blow it up, but that does not look practical to me. I used a tire pump with an adapter for exercise balls that I happened to already have. That worked great.Pro:It is very grippy, so it stays in place between your knees very easily during exercise.Conclusion:If you want a cheap ball to play with, go to Walmart and buy one out of the bin. If you want something to squeeze between your knees during exercise, this works very well.

This ball serves my needs well. Since I use it for core exercises barre-style I don't need it to inflate all the way, and it has stayed at exactly the same inflation for months without my having to blow it up again. Re-inflation is easy and the ball has nice give. It's a little smaller than I'd have liked, but that's me not knowing exactly what diameter I did want. Still, I use it and get a lot out of it.

The only problem I have with them is they run small. I have ordered 2 so far, 8 and 10 inches, still have not been able to get the right size!

This is a quality product. I need to use it for therapy on a regular basis. It holding up very well with adding air only once since I purchased. I am not very gentle with it, but it is holding up....Would recommend this for those who have little ability to squeeze to a good ability ....

This is a standard sized ball that is great for Pilates and specifically barre which is what I purchased it for. It’s great for mid core work, legs, etc.My toddler also loves it.

This works fine for me. I put too much air in it and can't figure out how to deflate it, so it's too big to use for my ab exercises. Great price, but just make sure you check to see how much air you need to put into it!

This is the perfect size for my 2 year old and 4 year old. I have one that I bought 2 years ago, and another that I bought recently. Great for catch, sitting on, and soft enough for dodge ball (they end up throwing them at each other lol). This is a great size as a workout tool for me as well.

I like how easy it was to inflate
