I really, truly don't understand it. Doctors, please correct me if and where I'm wrong here... This whole concept of "muscle memory" is the biggest joke ever. My understanding is that muscles don't have anything the brain doesn't give them, other than mass. It's truly the most fundamental and elementary of truths, that the musculatory system simply reacts to electrical impulses sent from the brain. So, the only muscle with memory is the brain and understanding that most basic of facts, training yourself to react to a specific situation in a specific way is a matter of conditioning. Now to understand what conditioning is. It's a set up for failure! This is what's wrong with all of you and all of your ideas of defensive drills. You're conditioning yourselves to respond to a singular dimensional scenario, but nothing is so streamline in murder or attack. This isn't the military, the bad guy isn't trained to fight any particular way that you can practice for, this isn't football, there's no position to guard, thus you SHOULD NOT train to defend so specifically! Learn good shooting stances and grips, absolutely! Understand pressure points and general defensive positions and concepts, yes. But DO NOT "train" for anything more than being aware and present. Example, training to move during altercation. Great, but where to move? What if attack is left, or behind, or beyond, or front center, or etc, or etc, or etc... Take things at more of a face value, your instinct will take control and do the right thing there. Stop over-estimating things. Anyway, this is my take, based on my understanding and person experiences. I'm no doctor nor have I been more than mugged, pistol whipped, and jumped before. This just seems the most logical thing to me.
