Hey Beth, I was just going to suggest BodyRX. I did that for a few weeks when I was just starting out on weight training. It was good but I ended up missing cardio. Here's a link to the site.

IMHO the 20 - 30 mins high intensity is great. and I include it in my workout routine after weights 4 times per week.
