I went to college in the early 70's with a guy from upstate NY who was a champion power lifter. He was in his mid 20's when he came to college because he traveled all over competing in lifting competitions. Either he or his family had money because he had a whole suite in the dorm....Dorm room, bathroom and another dorm room that usually 4 people shared. He lived in one dorm room and had all his free weights in the other dorm room. The guy was huge and we asked him one time if he had to take muscle relaxers to take his morning dump.
I personally watched him eat more than once a dozen boiled eggs he boiled on a hotplate in his room and eat a tub of sour cream to chase it down for breakfast. Never seen anything like it. He was one of the nicest guys on campus and more amazing than his size was he was a classical pianist...and a great one.
