I love using the Ab Lounger exerciser. It has helped me to obtain my goal of having a flatter stomach. I'm really surprised at how easy it is to use. I can do up to one hundred repetitions easily on it and not even realize I'm toning muscles. Within a week I had noticed that my pant size has started to go down considerably. Lately I have been using the Ab Lounger by itself and I have not been following any diet or other exercise program. My pants are now really loose and I was even able to go down another size. Laying back in the Ab Lounger is relaxing and comfortable, there is no strain on my back or neck whatsoever, that is what I like the most about this product. My only complaint about the construction quality of the product is that it does irritate the back of my legs as I'm moving, this causes minor irritation, but does not defer me from giving the product two thumbs up!
