What is group fitness really?

What's it like being a fitness professional? Just a regular person, with the regular aches and pains and the experience that I can feel better if I move. I believe in this fitness stuff, well not all of it, ah, well not most of it. When I focus on fit measurements like weight, BMI, calories, it sends my stress hormones crazy. Really, I became a group fitness professional because I love to dance to good music. The fitness profession was just a bonus. Do you have to know much anatomy and kinesiology to cue a rhythmic dance class? That's what I feel group fitness is, a rhythmic dance class. Well, I don't know all that academic stuff, but I do know how to cue a class to rhythmic music and get everybody moving to the same beat on the same foot and synchronize to synergize. Yeah, I know how to do that.
