I talk to Wim Deputter who is Belgium based Black belt in Brazilian Jiu-Jitsu. We discuss how Jiu-Jitsu is a principle that means a Boxer could be doing Jiu-Jitsu, but you could be a BJJ player and not be doing Jiu-Jitsu. How Wims “Mirroring Principle” is an algorithm and fundamental movement rule that guides BJJ, MMA, Striking and self-defence situations. How constraints placed on any art will determine what that art can become and how constraining beginners to focus on control and then to allow controlled chaos can be the best way for them to develop.
Wim is a life long martial artist also fighting MMA where he amassed a very respectable record of 18 and 4. He has done multiple seminars for the BJJ globetrotters organisation and has four instructionals out with BJJ fanatics that cover his mirroring principle.
