Query: Good aerobic workout

I just bought this and am still learning, but I like it. I am not a natural at dancing. It is a challenge for me to learn steps. I'm also not 20 years old, and there are some dance videos that have a little too much jumping (hard on the knees) for me. This one is good for getting the heart rate up without killing my joints. I bought the Latin dance video from 10 Minute Solution and finally learned to do all of it, so thought I'd order this one for variety. I think once I've got the steps down, I'm really going to enjoy it.
