Need advice for at home DVD.....

Options
I am a mom of 3 little kids. I have been doing some old VHS tapes..(yes that is the truth!!)....at home to get some exercise. I occasionally walk in a gym as well. I live in the Midwest and we currently have to much snow and cold outside for my kids. I enjoy low impact aerobics at a beginner level with possible transition to intermediate level. Any advice for a plus size mom who wants to actually be able to exercise with the instructor for a DVD to purchase. (No doing push ups, planks, etc.)

Thanks!!!
