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

I one of these at the recommendation of my Physical Therapist - not this specific one; but a burst proof exercise ball. I use it to do dumbbell presses on. I have had five shoulder surgeries and decades of lifting and powerlifting have taken its toll. I have significant osteoarthritis in both shoulders; and my surgeon told me after the last one that It is not a matter of if youll need a shoulder replacement, but when. My PT recommended this as a way to keep lifting and extend the life of my shoulders, especially the worse one. I havent done anything crazy; but have used 40lb dumbbells in each hand a couple times; and regularly use 30 or 35lb dumbbells. Between my weight and the dumbbells it is holding over 250 (or more) pounds. I have never felt that there was the slightest risk of a burst. Would definitely recommend.

Good to have it

Seems strong for therapy application. The pump supplied is too small for the large ball I bought, I have to use a boat pump to inflate mine, otherwise it may take a long time ~30+ minutes.

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.

Exactly as expected.

Update: I was contacted by customer service to resolve any issues i had with the ball and they were very pleasant to work with. I ended up sticking with a different ball I got at a local retailer but I do appreciate the effort for customer satisfaction!! I bought the large because I wanted something a little bigger like the ones I used at physical therapy. The Large says it is between 58-65cm. As you can see in the picture my ball is maybe 49cm and is relatively uncomfortable to use and I have it filled as full as I can get it. It also doesnt feel very sturdy, Im roughly 200lb and I feel like im going to pop it every time I use it and Im not even putting all my weight on it. Disappointing ball.

I bought this ball to help with my hip exercises. I use to stretch out my muscles and some core exercises.

Too small

Just what I was looking for to prepare for labor

This gym ball came with hand pump and it works great. I’m pregnant and having pubic pain. This ball helps me a lot.
