Zumba!

I am currently over-weight and I don't want to be anymore so I have started doing Zumba and hope to continue doing it while in Vietnam. Last time I was there I saw it advertised outside of a local gym.
What is Zumba? Well this is a quote from their website:

Zumba Fitness^® is the only Latin-inspired dance-fitness program that blends red-hot international music, created by Grammy Award-winning producers, and contagious steps to form a "fitness-party" that is downright addictive.

Since its inception in 2001, the Zumba program has grown to become the world's largest – and most successful – dance-fitness program with more than 12 million people of all shapes, sizes and ages taking weekly Zumba classes in over 110,000 locations across more than 125 countries.

So far I like it. I am not a fan of relentlessly perky instructors so sometimes I feel like punching the T.V. but aside from that it is fun.
