Do you believe it? Exercise ball instead of a chair?   

I myself have tried this and ended up losing 35lbs.....of course the only reason I lost the weight was because I was in a come for 6months after rolling off the ball and smashing my forehead against the edge of the table resulting in a fractured skull, minor brain damage and the aforementioned coma.....still, I now look fabulous in tight jeans but I have the head of Frankensteins monster

I have heard this too, but it is very hard. I mean, you will most likely have to ease yourself into it. I think that it is a good idea, my back hurts anyways from all the bad chairs that I've sat on all these years.

I've heard of people doing this but I don't know anyone that's actually done it. But it makes sense that it would help with the abdominal muscles...Lori

I think it would strengthen your abdominals and your back. Knowing me, I'd fall off!!

I have 2 friends ( both doctors) that have done this exact thing. They have told me I should try it...So I did...I haven't given up my computer chair yet...but borrowed their ball and loved it...It is recommended by many chiropractors...It is better for your back than most chairs...I am actually going to do it when I redo my computer room!

You use your core muscles to hold yourself up on the ball. I think it may be a little low tho.

My husbands chiropractor told us to do this. He said it would force us to have good posture instead of slumping in our Computer Chairs and help with our back pain. Of course we have an exercise ball and it's in our closet deflated. Guess I need to get it back out and use it instead of my computer chair. My new year's resolution was to get in better shape. Guess this is one way I could try.

Sound like may work for a short period of time but if you are posting on mylot it may bother your back. I would try b4 buying. If your friend has one, use it for a week; if it works then invest in your own. Let us know how it works out.

LOL that reminds me of an episode of "The Office" (Season 2 Episode 08 Performance Review). Dwight got an exercise ball and was using it at work... (shown in picture) anyway, the scene is hilarious!

As for the exercise ball, it would DEFINITELY help with balance and tighten your abs. It's difficult to learn to sit on it (without slipping off), but if you are willing to try, it's a great investment!

I do not know anyone who has done this.I will say that it sounds like a good suggestion to me, and I may try it. The different chairs I have used at the computer usually cause me to do strange things with my legs and end up with pain, or with numb spots on my posterior. It seems it would cause less back pain because you would be constantly moving and readjusting. Increased blood flow. I have one, I just need to dig it out.
