What are some of the worst things you have seen done in a gym?

Hey Jamie.
First thing in the morning at gyms, seen it all - from a woman sitting on a bench chatting away to her mate who was breast feeding on the leg press, a young guy performing kettlebell swings in front of a mirror - he should've used chalk, to a couple of guys in the squat rack, one of whom threw up mid rep and promptly moved to a different section of the gym without telling anybody! I was mortified!

My favorite so far is seeing someone fall asleep while walking on the treadmill! I've considered adding "not sleeping while operating motorized exercise equipment" to my exercise safety agreement after that incident!

Seeing young guys load the bench press, then having to run over to help get it off there neck!

Just saw a guy in the gym using an ab roller wheel. He was rolling it over his abs.

...what about using the squat rack to do biceps curls - Rrrrrrrr!

...and sitting on a piece of popular equipment between sets - hold me back!

I saw a guy the other day wearing a checkered long sleeve shirt and Chino's doing bicep curls in the squat rack with bad form and chatting to his 3 other mates during his 5min long rest periods... how many gym sins can you commit in one go?!

My mate also told me of one story, this is the text he sent me as it was written while we were having a convo about weird stuff we've seen in the gym, it made me laugh a lot at first but then I sort of felt sorry for the kid:

"The gym is quiet and its just me and another guy in the weights area, both got our music in doin our own thing. A kid in P.E. gear comes in, nothing unsual about that, lots of school kids join the gym. He's looking around, no idea what to do, goes back to a bike, pedals with his arms folded for 2-3mins, goes back to the weights area, fiddles with one side of the cable machine, gives up, goes to the other side which has the rope ready for tricep extensions, he goes for a rep, it doesn't move, he leaves... 10mins later he comes back, sees the other guy has finished with the EZ bar that he was curling. The kid sort of shuffles over in front of the mirror, picks it up, goes for a rep, is doesn't budge, he leaves... another 10mins later, I'm on the chest press machine, the kid comes in and walks straight to the weights area. I'm concentrating on my set and unaware of the kid, until (and I have my music in loud as usual) I hear this f***ing loud noise. I suddenly think he's just KO'd himself on the Smith's, so I turn around and he is on the TRX mat banging out 6-7 of THE most weird looking and f***ing loud clap/jump push ups I have ever seen. He face-smash fails the last one and just leaves. He got up and walked out as cool as a cucumber!"... poor kid!

My mate also told me he see's a guy regularly doing weighted dips, but not with a dipping belt, no no, with a headstrap and plate hanging from it... neck pain much? Ha

I've seen naked people bring dumbbells into the sauna. I've seen a drunk person fall off the treadmill. I've seen people spit on the gym floor. BUT...My personal favorite was a guy who climbed up on top of the weight assisted pull up machine, hooked his legs into the bar and tried to sit back and do inverted crunches. He was also wearing sunglasses (inside) and hit his head on the knee rest before he fell out sideways onto another piece of equipment.
