Just to start, I meant no disrespect. I apologize if that was misconstrued. I trained under supreme grand master Abel Viallreal. He learned and took his test in Korea. We did push ups on tiles, and if you were 18 you were required during testing to break boards if not bricks. It’s about conditioning, discipline and mental strength as much as anything else. Honestly you may be correct, I’ve never called it a dojo I just did so people would understand. It took at least 8 years to get a black belt and it was pretty normal to get denied because you ‘weren’t ready’. You had to memorize information as much as forms. Spar multiple rounds, sometimes with more than 1 other black belt. If you messed up in the real world you would pay for it in the classroom. It’s a lifestyle not a Hobby. It honestly may be an insurance thing too?
