When guys stopped having jobs and working and started acting like divas and princesses ?..
I'm guessing around the early-mid 1980's, 1983 or 1984 or so, around the Samir Bannout, Tom Platz, Lee Haney years...
I think by the 90's the general malaise and laziness became ridiculous, and no I don't consider personal training a few times a week 'work' or a 'job'
