What (who) annoys you at the gym?

The woman who brings her own little personal fan to aim at her on the cardio equipment. Oh and the woman who hides out in the locker room eating little debbie treats. That one about floored me. Really?? It's a gym...

The guy in speedo like shorts with chicken legs, no butt, big arms, big chest, and a big neck, not so much that he looks disturbing but that he grunts, moans, and throws down his weights.

Honestly? Guys who are already ridiculously ripped and continue to do weight and chisel. They're disproportionate and can't fun worth crap but hang out doing bicep curls...come on dude!

so i used to go to LA Fitness, the treadmills are upstairs overlooking the weight lifting area, and there were always these bleach blonde girls dressed in stripper clothes........ and i mean the tank tops with the "slit" between the boobs to show implant cleavage, 6-inch fake nails and tons of makeup, who would just walk around and never actually pick up a weight or use a machine. I used to just watch the show while I was running, it was sooooo entertaining. ---as a disclaimer i have bleach blonde hair and fake boobs, but i go to the gym in baggy sweats and no makeup SO THERE. (I'm sure all the guys are wondering where this LA Fitness is..........LOL)

Nude walkers in the locker room. It seems like every decade older you get, the more comfortable you are with less clothing. Grampa, stop shaving with your balls on the sink and put some clothes on.

I'm usually cool with someone working in on a machine that I'm using, but don't change the weight, change the handles on the cable and move everything around. If you want to use the cables to do back, and I'm doing triceps; you're gonna have to wait.

The old man last Sunday that was staring at me on a machine and then started trying to convince me to use a different machine WTF leave me alone.

I can't stand the women who walk around and act like they are better then everyone else. Oh, snd the chick yesterday that went into the steam room in a g string and bra with half her who ha showing...ewww!

liitle people using them !!!

Normally I don't like judging the people in the gym because they're at the gym. That's a step forward whether they are stepping towards the right direction or not. Also, just because they are on their cell phones doesn't mean they are just messing around, for all I know they are awaiting news from someone in the hospital.
But that's not the point. I've seen people in the gym not working out and that's life. People don't always do what they set out to do. The most annoying thing I've seen so far though is when a trainer (YES A TRAINER WHO WORKS IN THE GYM AND SHOULD KNOW BETTER) was holding up a machine because he was chatting to the person on it.
My workout buddies (and myself of course) were waiting to use it and we asked the guy in the machine how many sets he had left.
His answer: "I just need one more"
That one more set took 4 other exercises me and my buddies completed. It was three of us that day. We do four sets per exercise. That means this guy hogged the machine for 48 sets!
If it were two people chatting away, I'd be fine with it. I'd be annoyed, but I understand. This was a trainer (not the guy's trainer, just a trainer who doesn't seem to be working) chatting someone's ear off and not letting the guy do his thing. Seriously?

Hmm I have to say the girls who go and chest press 5 pounds and ask for a spot.. really?! Or, the obnoxious grunts and screams when doing weights :S

Never underestimate the power of the bar. 5 extra pounds can mean a total of 40lbs in some benches. It's smart to have a spot for chest press even if its little weight, you never know when a muscle is suddenly going to tense up between reps.
The grunts and screams do get annoying but understandable. Those grunts and screams give them the energy they need to finish it. If its 3 grunts, I don't mind it. Once it gets to 5 consecutive grunts, I think they should have waited another set to attempt the current weight.
