Very interesting discussion so far and it has peaked my interest a bit.
A question to those who have been doing this internal type training or whatever you want to call it for awhile...how has this type of training helped you in defending yourself against a violent attack? Has this type of training allowed you to do things (neutralize threats) quickly, efficiently, effortlessly, etc.? As I read thru these threads, the question in the back of my mind is, other than developing strong, core connections within the body for maximum efficiency, how will this type of training help me against a resisting attacker hell bent on hurting me? Maybe the answer is right there and I don't see it, but any help in explaining it to me would be greatly appreciated.
Roughly: increased relaxation, speed, agility, reactivity, strength, coordination, and balance.
