I also adore Zumba. I recommend you to include a little more upper body warm up (arms circle...etc) and 10-15 min yoga stretching at the end. Yoga is really great for cool down to avoid all sorts of pain.
If you want another dance program the Hip hop abs is good one. Its for whole body (not just abs) with hiphop music (logically, eh
). Maybe you also like belly dancing. I've not tried any but Ive heard its fun.
