I got the balance ball for my birthday and have been using it every day! I want to be able to workout at home because I don't want to have to pay for gym memberships when I feel I don't go enough to make it worthwhile. Also, I use the balance ball when I'm at my computer so I can be a little more active by rolling on it, twisting on it and doing sit-ups and use the dumbells on it while waiting for things to load.
I just push the computer chair off to the side and my cats make use of it. I love it because they are closer and easier to reach now and I just love petting them. They seem to generally like it too and they patiently wait their turn to blog but enjoy watching me. Normally, just one comes at a time but over the weekend, both of them shared the chair! So this is the added benefit of my Balance ball.
I have also used it while watching a fitness show on FitTV that was a real workout. That is a good station for fitness because they have different trainers and a wide variety of exercises so I don't get bored doing the same things all the time, which really isn't good anyhow. With my balance ball also came a big poster with exercises targeting different areas. I did the legs and hips. I think I will get a lot of use out of this so it was worth the money. Those sessions with a live trainers are expensive and so are gym memberships if you don't go at least three times a week!
I highly recommend the balance ball! What exercise equipment do you especially like?
