I am in my gym all day and I really take in everything that is happening there and here is my take. I don't think it's actually ego lifting, I honestly just think everyone is stupid. They just honestly bastardize every fucking exercise so bad it becomes another new exercise because they are just too lazy or don't give a fuck to learn how to do it right. The ego part might come into play because god forbid they should actually go up to another adult man and say "hey, i'm not sure that i'm doing this right, could you give me a hand?" That would too much a sign of weakness I guess. And god forbid I, as the owner of the gym, should dare correct anyone in the most polite and subtle way for fear of them taking it as an insult. I'm to the point now where I watch people workout wrong ALLL day and night and don't say a fucking word unless i'm asked for help (which rarely ever happens). I will step in if I see something really life threatening going on though.
Very interesting topic though.
