I have always had a problem doing sit ups. They always just hurt my back too much, ot maybe I just wan not doing it correctly. I wanted to get something to work on just the abs that would also be easy on my back. My daughter recommended the AB lounge sport. I went around to a few stores to check on prices. I found that Wal Mart had the best deal. What I love about this item is that you get a pamphlet of instructions, some recipes, but also a CD which shows you beginning and intermediate exercises. Once you get the rhythm its easy. I started out with the recommended 10 reps in 3 different positions. I have only had it for 3 weeks, but I have advanced to 3 sets of 10 now. My back and neck does not hurt. I feel better in the tummy area. The only down side was putting it together. I had to have someone help me to finish- but then I am not the greatest at putting things together. All in all I love it.
