When a person does the same thing hundreds of times, with time the movements are optimized to the most optimal and are done already on the machine. When I carry the tea from the kitchen to the comp, I have the perfectly established shortest route, my little one stops in millimeters from the plintus at the corners, the shoulder is pushed up during the turn around the chest, and after entering the room, the hand pushes the door precisely with such force that all inertia ends in a millimetre from the touch of the door and the chest and silently closes. So it’s not just athletes who have perfect movements.
