I used to work at the gym when I first moved to DC. Things I've seen:
1. Men rushing out of the locker room to tell us that 2 guys were having sex in the sauna
2. Guy picked a scab in his nose and was bleeding everywhere, I mean he had 3 towels covered in blood, and people were freaking out. I thought he was having some sort of uncontrollable nose bleed and he just said "I picked a scab" I guess this had to be done at the gym.
3. Multiple reports of guys beating off in the steam room
4. Gay cycling instructor shaving his legs in the shower with the curtain open
5. Way, way too many bad exercise/bad form stories to type out.
6. Shirtless guy in the men's locker room taking pictures of his biceps
At my current gym there is a guy that works out in his socks. I have no idea what is going on there.
Also, similar to post #29, some guy was trying to put weights on his thighs/stomach to do some sort of thrust with his legs. He asked me to spot him and I laughed in his face and walked away.
-This is a great topic, BTW
