Zumba is not a flirting sport
Call me old school, if you want to flirt, go somewhere else to do it. In a dance studio and in a Zumba class, it is about Zumba. Why Zumba is so interesting and effective is because it ditches the workout and moves with the music. Jumping around, moving your butt, they help to shed calories and build your cardio strength.
Well, if you gonna flirt with the instructor, please do it outside the class. If you are married and have kids, know your status. 人要学自爱！
