There is a guy in nyc that runs a kickboxing guy. He is this short guy with a big pot belly. He competed once in a kickboxing match and was destroyed by his opponent. A few of his students won some competition but that is a given. Own a gym with good facilities and you are bound to have a few winners. I have seen crappy teachers have winning students. Would anyone study kickboxing from an overweight, out of shape guy, that competed once[and got his ass handed to him] and is making his pockets fat from prostituting the arts?
