I would say try out a class or two as well. I did $5 a class Zumba up to 5 times a week in January and February before I joined the YMCA. Now, I'm taking a bunch of different classes and love the variety. I love classes. I had never taken one till January though. I'm not even an outgoing confident type person either. Also, I'm quite uncoordinated

I like to be in the back row next to a wall...
Edited to say that I started Zumba as a beginner. I used to be in shape but hadn't been for quite some time. I was sore for a while but eventually not so much. q
