This ball lives in my living room. When we don't feel like sitting on the floor, my husband or I will sit on it. It's fun to bounce up & down & laugh at each other. I know I'm supposed to use it for exercise, but I plan to bring it to work & use it to sit on. I've heard that works your core muscles because you're balancing all day long. I'm hoping it will be high enough that I can still reach my keyboard & see my screen. I didn't know it came with a pump that you just step on to fill the ball with air. I really was happy to get this when it arrived & it still makes me happy every time I see it.

I bought this to use as an office chair, and it is working out great. I had ordered a different ball that was smaller than advertised and took forever to blow up b/c it only came with a small hand pump. This one comes with a foot pump that is much more effective. I inflated it with no problem and am loving it. For anyone interested in replacing their office chair with a balance ball, I recommend this one. I am 5'8" and for my height most people recommend a 65cm ball, but I find the 75cm ball much more comfortable. If you are tall and have long legs, I would recommend purchasing the 75cm ball.

I ordered this ball after my physician said he uses one, and that my physical therapy would benefit using some of the exercises with the ball. And it has! I am a larger size woman, and this ball can take me sitting on it, and rotating my axis points back and forth. I'm pleased with it, and will start following the included poster of exercises next.

There's nothing magical about this piece of equipment- its a big, sturdy rubber ball, and what you see in the picture is exactly what you get. So why would you even want to bother messing with it?

Well, despite its simplicity, its a really FUN piece of exercise equipment and an absolutely GREAT way to change things up. For instance, if you're tired of doing sit-ups on the floor, well, try them on the ball (you'll see what I mean when you do). If you're tired of doing push-ups on the floor, just try them with your feet on the ball- then see how many push-ups you can do!

But be careful and use your judgement. While there's a lot of stuff you can do with this big ball, you COULD also get hurt if you're clowning around or trying something you're simply not in shape to do yet. Know that this ball comes with an exercise sheet that give you suggestions for doing different exercises.

All-in-all, though, its especially nice for a change of pace or for an added challenge. Additionally, many therapists use this ball for rehabilitation purposes, particularly back rehab, so there's really a lot you can do with it. If nothing else, pull it out after a long day at the office and stretch your back out over it- wow- does that ever feel good! Those who suffer with back pain might also be interested in Treat Your Own Spinal Stenosis. Have fun!

This exercise ball is of good quality and perfect for it's designed purpose. I was less thrilled with the pump that it comes with to fill the ball - it's a very small pump, so you spend a lot of time either stepping on the pump or squeezing it. It also has some connection issues with the tube you connect to the pump - it fits snugly (no leaking) but tends to fall out a lot, especially since you're pumping a lot to fill it up. But I suppose you only really need to fill the ball every once in awhile, so its not that much of a deal breaker.
