Master Roger Koo created Koo Self Defense in 1992 from a completely different 'out of the box' approach. Although he was trained in various martial arts, his unique concept was to develop a training curriculum, not a style based purely on a simple premise: A Martial Art & Self Defense Training System = Extreme Physical Fitness + Devastating Power This is what Koo Self Defense represents.
