I was looking for an exercise video with exercises targeted on the abs that didn't take a lot of time. This has really met my need. I can almost always fit 8 minutes into my schedule every day and it's not too boring. Instructions are clear and no equipment is required. The only drawback is that this is a double sided dvd and you have to eject and turn it over to do all 4 segments.
