Seattle: Free Zumba classes in February.

I've been hearing a lot about this Zumba craze that's sweeping the nation, and it kind of sounds fun. An hour-long dance party that magically burns away the calories? Sign me up!

Of course, all these exercise class memberships can be expensive, and it's a big commitment when you don't even know that you'll like it. So I was happy to see that Seattle's Dance Underground is offering free Zumba classes every Saturday in February. No registration is required — it's a drop-in class, first come first serve. They just ask that you fill out a health release form and bring it in to expedite things. JAZZ HANDS!
