So what's so special about "attacking the core"? All MA systems does that. When you
- swing a hay-maker,
- throw a roundhouse kick,
- lift your leg between your opponent's groin,
- ...
you are attacking your opponent's "core".
To me, the "centerline" theory is to "attack through the "front door" - attack between both arms".
Here is where we will part ways John. Because I don't think you have to be between the opponent's arms to be using centerline theory. In an empty hand vs. empty hand situation, if I have grabbed one of his wrist/arms with a Lop Sau to turn him away from me and disrupt his balance while exposing his flank......and at the same time throwing a drilling punch into his ribs with the force focused directly into his motherline.......I have used centerline theory without staying between his arms.
