I also do weight training at home with a bench and a set of dumbbells.
I use the Leslie Sansone Walk Away The Pounds videos. I started with this set:

I also use these, which do not incorporate weights:

http://www.amazon.com/exec/obidos/ASIN/B00008DDJD/ref=pd_ecc_rvi_f/104-1525466-4869541I have a power mile DVD also. I really like that one and will sometimes do it two or three times in a row for a variation instead of one of the other extended programs.
These programs are great, in my opinion. The varying walking moves, plus the pace, are great not only for cardio, but for strengthening/building the muscles of the lower body. The upper body moves - with or without the weights - add to the calorie burn and strengthening. Because I do lift weights at a much heavier level three days a week, I like the little extra kick of the light weights in the videos. (And I should add that the WATP videos have done more to help my rear end defy gravity than the previous 10 months of using the elliptical trainer and step climber did!)
I also like these programs because the moves are very easy to follow. Anyone can do them. Some people find Leslie to be too chatty and annoying, but I like her cheerful banter. It makes the workouts speed by, and I feel like I'm really with a group of people.
