Query: Good weights workout, informal, not a lot of cardio

I bought this DVD for a weights routine, and that is definitely what it is! There is a warmup, and they keep you moving a bit so your heart rate doesn't drop completely, but it is not a cardio workout. I think Summer and her sister in law are funny during the workout, but it is definitely informal. I do this routine at least twice a week, and recommend it for a nice change up to prenatal yoga!! I rotate yoga, this routine, and walking and I seem to be keeping in shape just fine.
