In my experience, as long as people are young say <25 something as simple, easy and straightforward as body-building fixes it. 30+ that gets harder because one has less energy, less time, less desire for doing stuff like this, at least in my case, as my dad used to say "too old for being a clown now", but at 20 or so any guy with a broad chest is going to get indicators of interest.
