Hmmmm, I think there is a difference between living a healthy lifestyle and being a "bodybuilder".... where is working out just keeping fit and when does it become bodybuilding?
I competed in a bunch of shows with little to no drugs and always having a job that was outside of BB.
I even won a few times and placed well in some decent sized shows. I was lucky enough to even beat those who went to extremes with drugs and did NOTHING but train for a show, etc.
Sergio Olivia worked in a steel mill for serval hrs per day before he was Mr O.
Ronnie was a full time cop while he was Mr O during his first few wins.
The failure to integrate a meaningful life with serious training is something that is an individual issue.
