TKO Anti Burst Fitness Ball Set 55cm

The ball is quite sturdy, the hand pump is a workout in itself. The sizing is confusing, among all brands, they can't agree. The box says the 55cm is for 5'6"-6'0", I bought this ball under the impression that 55cm was the size for anyone under 5'4". This is my reality: 5'2", 190lbs, looking mostly for something other than the couch to sit on, working on core strength. This ball is smaller than I wanted, my legs do not make 90 degree angle. Maybe I am too heavy, or perhaps after a few days I will be able to get more air in it. It will be great for exercizes where I hold it between my arms or legs, but for sitting on, or push-ups I will order a 65cm ball. My recommendation is to skip the sizing charts, find someone with a ball and decide for yourself which size suits your needs. Shipping was fine.

I hate exercise. That said, using this ball is really very fun! I can watch TV while using this, and forget I'm even exercising. My abs and thighs were really feeling it the day after I started. I can use it whenever I want, which is the big draw for me. Try it, you'll like it, even you lazy slugs, like me!

The ball is working out fine so far, and was delivered in a timely fashion.

This ball is wonderful! It has proved to be the best purchase I've made this year. I have arthritis and I generally do water aerobics for exercise, but now I can alternate with my stability ball because all the exercises have a low impact on my joints!!! Thank TKO for making it "anti-burst" because the one I bought a few years ago, did just that. Now, I don't have to be so extremely careful of this one because the outer skin is tougher! I would definitely recommend this product to anyone looking for a low impact way to exercise.

No nasty plastic smell and residue when using it. Has a metallic tint to it and looks nice. Included hand pump did what it suppose to do. I am 5'1" and 200 lbs and this ball is doing a great job. It gets a bit "soft and saggy" when lying on it but I guess thats what makes it anti-burst. I counter it by pumping the ball a bit more air into it and it is now working greater than ever. Included poster/exercise guide is good. I have owned the ball for over a month and the air has not leak a bit. My 250 lbs sibling was using it and no complaint. My cousin also used the ball as a chair while playing video game and he said it helps keep him in good posture. The ball does LOOK a but small for a 5'1" person but for a beginner this ball is definitely the right size to WORK with. Might buy a bigger one in the future when I am ready for the challenge.
