Just the thing I need to support my lower back when doing squats. I have my feet out to keep my knees in position and my arms at my sides. Just like the physical therapist showed me.

comfortable to sit on (when I can get my dog to quit playing with it :) ), durable

Excellent - made well, very durable and my physical therapist approves of it.

excellent quality

Item as promised and fast delivery

Classic model. Very firm. Exactly what I need.

Very strong material. Easily withstood 250 pound man jumping on it when stationary. Highly recommend.

Perfect size for crunches. Feels very durable.

Quality is great and it continues to perform as expected.

I love this ball personally. I use it instead of a desk chair and I haven't had any low back pain since. It is high quality and doesn't feel or smell weird like a lot of others. It is definitely worth the price, you get what you pay for.I have ordered these for myself and a lot of people in my office. The only thing I would caution is that for the vast majority of people need the 22 ball. I have a few people that don't have short legs and are 5'7 and this ball is too big for them. I ordered the 22 and it is perfect for nearly everyone unless they are really tall. Especially since they stretch and you need to put air in on occasion to keep it the right firmness to be therapeutic, the 26 can get too big in a hurry.Don't be deceived by it looking so small when you start pumping it up, they expand A LOT!! Once it is done stretching, this one is often too big.

This is the same ball that I use at PT and wanted one for continuing my exercises at home. It is sturdy and just the right size. It's a size above what was recommended for my height, but turns out it is actually the size I need. I love it being yellow...it's just like a big ball of sunshine that makes working out that much more fun. I highly recommend it.

Great value! Unlike so many of the cheap fitness balls, the walls on the Gymnic Classic are thick (rather than see-through!) and the line construction around the ball is uniform and even. Bought this for physical therapy, and it held both air and shape far longer and better than the other two lesser-quality balls from different vendors--- even though those balls were 'rated for more weight and taller people! When it comes to fitness balls, you get exactly what you pay for. The Gymnic Classic is worth every cent, and I won't bother wasting money on the junky competitors.ever again.Basic money rule: If I pay $45 for the Gymnic once and use it for a year, it cost me $45. If I pay $15 for a knock-off, I'll have to replace the knock-off at least 4-6 times in a year...that's $60-$90 a year. Buy it once, buy it right. I don't work for Gymnic, sell their stuff, or get any money for this (though if they sent me a free ball, I wouldn't return it!), but their ball is head and shoulders above any of the competing brands I've used over 6 years of physical therapy.

I have not had a chance to blow it up or use it but it looks good. I love this brand and trust it. It arrived quick and on time.

The Gymnic Exercise ball is the most sturdy and non-burstable exercise ball that I have purchased. It was recommended by a physical therapist, after I had tried several other brands and types. I am quite please how sturdy and durable the ball has been and would recommend it to anyone with a need to work in an exercise program. Because it is so sturdy, I also use the ball as the seat for my desk, because it helps me balance and keep a proper posture, while exercising my stomach and leg muscles.

We bought this ball because it was used in our labor classes and they recommended this particular brand and size for use during labor because it is very high quality. We will be using it to sit on and lean on in order to keep moving during labor and help the baby move more quickly into position. It comes with a list of other exercises you can use it for as well. Very happy with this purchase.

We got this ball for the Grand Kids and they love it. It's rugged, and looks like it will serve us well for a long time. We would get another if needed, and maybe a larger one as they grow up. Great way to get some of that excess energy burned off.

I love this excercise ball. The quality far surpasses any that I have used before. I would recommend this to anyone who wants to get fit.

I use these balls at the fitness center, and find them to be flexible and easy to maneuver. They have really helped my core strength, have aided my flexibility, and reduced my back pain. They do come in colors and sizes.

This is the same ball used by my physical therapists. It does take a two stage inflation to get it to size without a compressor. Very durable and easy to use. No bad plastic smell like some other balls.
