of course it would affect you, physical jobs definitely affect you. I'm aware that many, many fighters have had strenuous day jobs but we're not there to see how hard they really work. Joe Frazier worked in a meatplant, Hagler was a construction worker, Charley Burley worked in a mill etc.., etc.., Usually though, if they had a fight coming up, their bosses would give them time off for it, in Hagler's case, his trainers also owned the construction company he worked for. Personally, when I had ambitions of getting some pro fights going in mma/martial arts, my body wouldn't cooperate so I tried to push the trainers to see how fast they could make things happen, as it turned out everytime, managers, promoters don't really do shit, they are lazy as fuck in my experience so I just wasn't going to sit around waiting for them to get it together. Most fighters do let themselves get fucked around and they end up often bitter and angry for it. Back to the question though, it depends on the person, if you've got a goofball who doesn't really put much into anything they do then yea, they can work at a mill and train, those types really don't work that hard. But, to do it properly? Hell no, no way. A workday is 8 hours, and some jobs require work every bit or more intense than a workout only longer. No way that helps a fighter. Injury and burnout are soon to follow.
