Mary, do you think that Benson Henderson is just a gifted person who has never learned-trained-conditioned his body to fight the way he fights? Of course he had to learn and train these things, reforming his mind-body wiring - including not just how he moves, but how he strategizes and thinks tactics-wise. As Janet pointed out, the way one moves in any discipline is not innate, it is learned. Once learned and trained to the point of "second nature," we can then act without cognitively having to oversee each movement. However, we continue to maintain awareness at all times, which is a different thing.
1. If we are not consciously thinking about the goal of the learning and mindfully training our movements, then we are giving up control of this process to either a teacher or to random chance, neither of which befits anyone other than a raw beginner.
2. If you really think that "in the moment" you are going 100% on instinct, you are wrong. If you simply go on autopilot, you will move in set patterns that will NOT match the actual changing reality in front of you and will never be able to respond to actual changing conditions. I've been in enough emergencies to understand the critical balance between trusting previously set patterns and maintaining not just awareness but executive function.
