By legit i mean instructors who are actually good at the martial arts and know what theyre doing. I know a good way would be to go to a couple classes but it could be hard to tell by just a couple classes. The reason i ask is i have been practicing hapkido for 3 years, and i want to broaden my experience and learn Kung Fu and Tai Chi as well. i know this could be hard to fit all three classes in but its something i really want to do so how does one choose a good instructor?
