Trideer Extra Thick Yoga Ball Exercise Ball, 5 Sizes Ball Chair, Heavy Duty Swiss Ball for Balance, Stability, Pregnancy, Physical Therapy, Quick Pump Included

My initial review was 5 stars: Unlike most buyers here I did not actually buy this for myself. My sons gym teacher recommended this as a tool to help him build up his core strength, which was below average. This ball has already made a huge difference in his ability to balance after a very short time of use. Thus far it has been easier to motivate him to use this as a chair to somewhat passively work on his core, than it has been to get him to practice more active exercises. Since my initial purchase I have purchased more and unfortunately my second ball (purple) for my younger child started deflating by nightfall. It arrived with a slow leak, so although it is usable it is very tedious to constantly refill it every morning.

Good product

I am 5 1 and I have the xl ball, my legs dont reach the ground have to put my feet on a stool. I use the ball for my desk chair.. loving it other than the fact I dont reach the ground.

Strengthing my core

Good quality exercise ball and when Amazon sent me an opened package without one component, the company responded with the missing piece immediately

It’s not easy to put in stopper. You’re trying to prevent air from coming out, and shove the plug in at the same time, while air gushes out. I needed a second person. And even then, it was a little tricky. I’m still not sure if I have the right amount of air. But it works. After all that was over, it’s been great. My lower back feels better. And my abs feel like they’re actually getting worked. I watch tv and am able to move around. Sitting still can be rough, and I can’t always go outside for walks in the winter. A great work out if you need veeeery low effort. Also great for stimming.

The 55cm exercise ball fits my needs, thank you for this quality product.

It’s very strong and pliable. Filled it up. Once months later it’s still holding air and it’s used by two people.

I bought this for my pregnancy and it helped stretch my hips and back throughout the last few months. Perfect size for my 5’3” frame

I love this yoga ball. I used it while I was pregnant and it helped me a bit. The only thing is people kept saying to make sure you get your right size and I got a L and I wished I got a XL. I was a bit closer to the ground with knee problems so if you are 5’6 and thing a L will be good. Try a XL and see. But great yoga ball in general!
