So, I just bought the Zumba DVD set. I've been wanting to buy it for a while - I wanted to start off with one disc because I couldn't fathom buying a 5 disc set for $60 if I didn't like it. After like 6 months of searching for only one disc I broke down and bought the 5 disc set. I seriously wasted 6 months of my life by not buying it earlier! This is awesome. I can feel all the areas I'm really concerned about getting a workout. Anybody else do Zumba? Have you gotten good results?
