We are on Marine Recruit Depot Sand Diego (boot camp) and we had already broken a sweat and our backs before the recruits had gotten out of their racks! When they finally got out to the fields for their PT session (which ended well before ours despite starting an hour later) the look on their faces was epic. The drill instructors stopped their PT and put them in formation to watch sergeants, staff sergeants, gunnery sergeants and a major move past their field. "That's what real PT is you maggots" I heard the drill instructor say to them.
