I don't actually know how to answer this question, but I'm blown away by your dedication. Picking a job on the basis of how it will effect your workouts? Ok I'll take a stab - Bouncer. You work nights with other gearheads and all you will talk about is gear, working out, and pussy. Trust me that's it, ask anything that requires deep thought and all you will get is blank stares. You have all day to work out. This is of course assuming you have been working out awhile and have the size for the job.
