I've been around gyms for years and never seen anything like this happen.
I have seen/heard guys yelling on every rep and it is both funny an annoying at the same time. It does make for a great workout though. Men need a place to let loose and channel all their testonogenic energy away without hurting others. This place should be World's, Gold's or Powerhouse gym. But we all know it is getting harder and harder to act like an aggressive man, even when lifting 300-400-500 lbs. Surrounded by metrosexual males with too much hair gel, designer shoes, and long basketball shorts worn to cover legs a baby chicken would be ashamed to show in public, the real men are punished or kicked out for simply being a man.
Rocky said it best to Adrean, "I don't ask you to stop being a woman. Don't ask me to stop being a man." Yeah, it is that simple. Women who can't handle being around large, muscular men lifting weights need to get a reality check. It isn't going to change. EVER! Real men cannot stop being men just because some 143lbs trainer tells him to pipe down. And the reality is such men will always find a gym to train at OR bounce back and forth between mutiple gyms if people complain.
With this said, no reason to go overboard and be an ass. But do grunt or even scream if you feel like it. Every once in a while lift up your arms while some metrosexual kid is lifting up his shirt in the gym for the ladies. Own them, give a hearty chuckle, bang some weights.
I just realized this is probably good enough to submit to ANIMAL training lol.
HARDCORE!!!
