Sorry for posting twice, past the 5 min edit thing..
Rhino is right, "Muscle memory" isnt the right term, that refers to performing a motor skill (like pitching, making a pass in a sport, throwing a punch properly, juggling, doing a backflip in an extreme sport, etc etc) its the body knowing how to perform an action because the action itself has been reinforced and you will "automatically" do it properly without thinking about it. This applies to anything like i said, even doing lifts with proper form, im sure a lot of people on here dont need to "think" about how to perform a squat or a deadlift properly, while newer people (like me even) need to think about it still when trying higher weights.
That said, the discussion on what the OP remains the same, heh. Hope i helped a little!
