So, I've just found out my gym has 3 kickboxing classes a week. I initially thought these were the usual cardio kickboxing class, but inquired about them anyway. I was assured by the gym manager that the classes are taught by a kickboxing professional, they spar, and some of the even enter tournaments, and also "the group works towards belts, gradings..."
Now, having not does kickboxing before, I don't know, but belts? Gradings? Are these things normal?
