When I see young skinny kids doing stupid stuff, it really doesn't bug me. I just think they don't know any better and let them get on about their business. They're usually the only ones I see curling in the squat rack. It's annoying, but I give them newbie slack.
I've only seen 4 d-bags that really stand out since re-acquainting myself with the gym this past several months:
1. Guy who puts 275lbs on bench and has little buddy spot him. Looking at the guy I honestly thought he'd be able to handle it, so didn't think much of it. 275 isn't that much. He then struggles on the eccentric only to get the weight stuck on his chest, requiring his little buddy to put his back into getting it up. Just when I think the comedy has let up, he proceeds to go for rep #2! At this point, my wife and I are LOL'ing and have completely paused our squat routine. A few minutes later, he proceeds to drop down to 245lbs. He, again, couldn't get it up once by himself and this time put his buddy through three massively assisted reps that probably gave the guy a herniated disk. WTF is a guy who can't do 245 x 1 doing putting 275 on the bench, let alone making his 150lb friend SLDL the weight off of his chest? He deserved some kind of award IMO.
2. 60 yr old fat guy who puts 14 plates on each side of the leg press and proceeds to do 1.5" reps like a boss. I was hoping to get in on the leg press soon, so I kept an eye on him. But, I eventually had to give up as he proceeded to drop set down to 3 plates per side, never getting more than 2" of depth on his rep. Don't get me wrong, I'm not one of those guys who believes you need to drop the leg press to bottom, rounding out your lumbar spine and giving yourself a herniation. This guy was literally just moving 1-2" at best.
3. 50 year old fat and haggard lady who lifts with some same-aged guy (actually in pretty good shape) who screams with all of his reps,a nd with all of his training partners reps. He cracks me up, but she defintely is a d-bag. A few sessions back, my wife and I were doing DB curls next to her as she "counseled" this dude on how to lift. Her cottage-cheesy ass and huge gut sitting atop stick legs were all that I could see as her leathery-flapping head proceeded to tell this guy how she does about 15 pull-ups and how he needs to man-up and do them. o_0 wut?
4. Pretty big guy in my gym, in good shape, was super-setting between like three machines. Random nice guy doesn't notice and sits on one of his pieces of equipment. Then big guy runs over there like someone is about to steal his little sisters virginity like, "hey, hey, I'm still using that, bro!".
