"guys that check you out"
You'd have to be more descriptive than that. A gay sort of check out or checking definition. I'll check out the development on a few folks. With my work outs, I'll see guys with these gigantic shoulders (my weak point) and have to wonder how much time they spend in the gym to get there
"machines"
What's wrong with machines? It's a gym. There are some things you need to use machines for in order to work on muscles, such as leg lifts. I do about half machines and half weights.
"bench shirt"
I had to look up bench shirts. I can't say that I've seen these in the gym.
"grunters"
My wife hates these folks too. I have to say I'll have to grunt once in a while, especially on the 18th rep of the 3rd set and I'm pushing to get the last two.
"look in the mirror" + "flexing"
I'll watch myself in the mirror for most of the arm and shoulder exercises to make sure I'm doing it right. Besides, you have to look somewhere
And one of the books I read showed that flexing was beneficial. Of course I'd expect that for the big-time body builders and not joe schmoe at the corner 24 hour fitness, but hey, you have to start somewhere.
"body odor"
I do my best here but I've yet to find a good deodorant that does more than cover up the smell (which is really the only thing they do). It's a gym, there's going to be smelly people in there. I'd rather smell some body odor than all that fru-fru body wash crap. Of course if you haven't washed your clothes for a month and take showers every Saturday whether you need them or not, then yea, I'm with you.
