I use this as a supplement to my FitMama Dvd. I am an intermediate excerciser, and in pretty good shape. I liked the pre-natal disk. There are 3/ 10 minute toning workouts for lower body,arms,and abs. The lower body & arms are really good.I don't really care for the abs section much. My only complaint is that she is a little annoying which can be ignored, and she tells you to hold your breath for way to long which is not good for you. Otherwise it's really good for toning. I only watched the Post-natal but it looks like it's probably just as good. These are good for maintaining your current level of toning, and probably won't get you into shape unless you normally don't excercise at all.
