Is your coach Mario Yokohama?
is this recent? gracie barra korea is gone isn't it?
anyways more than enough gyms to train in seoul. if you need recommendations shoot me a fb msg to my academy or something.
Wut? If my professor ever told me I wasn't allowed to supplement my training with instructionals, YouTube, or by watching black belt competitions and I was ONLY allowed to use techniques that he personally showed me, I'd leave. That's absurd.
