a good friend of mine named Len Bosland was the 1953 Mr New Jersey.
he is an old timer that tells great stories.
besides competing, he also MC'd the Mr Olympia a bunch of times back in the 70's and 80's
he tells me that back in the 50's, nobody trained until it was show time. most guys lost their appetite so they never got fat...and when it was time for a show they would eat foods like whole eggs, steak, and milk, on a routine of 5 meals a day.
he told me that the year he won the Mr NJ title, he thought....i want to win this title, why should i stop training in the offseason?
so he continued to eat good and train hard all year long, and when he showed up at the show he shocked a few with his new look.
also, i trained with 84 nationals, and universe champion john hynatshack for his 3rd place finish in the 2000 masters olympia.
he told me that back in the 80's guys never did cardio.
