Color belts need to practice these huge actions to train their bodies to make power. Eventually, they won't need to, and you won't have to make those actions in a real situation. Your kicking, punching, and blocking will become so smooth with time and practice that the windup and cjambering will become almost imperceptible.
That is a difference between beginning and advanced students.
This is the point I was attempting to make... which will teach me to post such things before I'm really awake.
