I'm being harassed by my co-workers to try Zumba. I've finally given in to their pleas, but what the heck am I getting myself into?

I can't dance to save my life. It's extreme enough that my husband and I had a no-dance reception at our wedding in 2004. He's less coordinated than I am! I can at least roller skate, ice skate, etc...he can handle riding a bike.

The girls tell me that one session of Zumba (45 minutes or so?) burns about 400 calories--which is twice what I burn now on the treadmill in 30 minutes. So I like the sound of that. BUT I CAN'T DANCE. And I have a bona fide fear of failure.

I'll try anything once (or 3 times, in this case), but I'm REALLY nervous. So...are there any non-coordinated people like me that Zumba--and LOVE IT?!?!
