I used to teach in the shittiest inner city districts. They liked me for my size, but didnt like that I was unorthodox-meanwhile I was nominated for teacher of the year back in 2002. I can wipe my ass with the cheesy little certificate. I own a small franchise that does pretty well. Not a WOW. They suck. My mainstream is personal training. I literally train anyone in the world.
