About Koo Self Defense The Ultimate In Fitness & Maximum Power
The ultimate in Physical Fitness & Knockout Power. 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.
