I will say there's nothing like a live Zumba class. It's truly like a party - like you're dancing at a club for an hour... and the time just FLIES by! I rarely want it to end! For the last year and a half I've been working to make lunchtime Zumba classes available to associates of the company I'm employed with. I think we're really close, but I wanted the option to use these DVDs until the classes begin and afterwards! Check out Zumba.com for more info!
