I work at a GOLDS guys and you would not believe all of the stupid shit Ive seen LOL. I agree with DirtyD and AJ for sure. If youre doing a VERY heavy compound movement WITH PROPER FORM then you might need to let out some anger and get some air out fast. That being said 99% of the time it happens at a gym its not nessecary and Ive trained at venice around top IFBB pros and seen Lee P train alot when he used to train at my gym and not once have I ever seen any of those bros make fools of themselves and call atttention to themselves buy making a scence. Sure bros like Ronnie and Branch are gonna yell and drop fbombs while they train LOL but they do it at smaller private gyms and they have earned it so to speak. It reminds me of something I read Arnold say that was something to the effect of: the guys that show off constantly with undersized clothes and noise do it for attention. A true mass monster or brother of the iron will not carry on that way. If one guy has a toyota corrolla sport edition with a super charger he'll speed around at every light every chance he gets to show off. The guy who has the american muscle car or the Lambo (somethin with REAL horses) or something to that effect cant do that cause when he puts the pedal to the floor it is ACTUALLY dangerous so to speak and the guy with the power cant afford that luxury or immature behavior. Sorry for the rant but hopefully you get my point LOL. The guys with weight belts and wrist straps that wear them the whole workout of freakin hilarious
