Query: Tough to learn, but worth it

The first time I put this video in, I was totally lost. But learning the routine is so worth it. It is fun and the dancers are a great group, and being able to do the whole dance is something I am glad I accomplished. If dancing is not your thing and you're not willing to put a little time into learning it, skip this one. Personally, I love this workout.
