I used to use it when I had a VCR since I had it on tape. I loved it. It had many different crunches to do in 8 minutes. Some were quite difficult at first. But overall, it worked great. The previous poster is right that it may be a little difficult at first, but it works if you stick with it. Nowadays, I try to replicate the 8 minutes abs video when I do my ab workouts.
