That sounds normal to me.
I don't find that Zumba is a very complete workout, even in the most intense classes. You may need to add some strength training or other cardio for a more complete workout plan. 2-3 Zumba or other dance classes per week is my limit. Also, Zumba is fairly high-impact, so you might want to alternate it with more low-impact exercises like swimming.
