things I learned at my gym
The gym I'm going to has made me paranoid to deadlift. The first time they complained I was making too much noise (my deadlift is stronger than my grip, so I would drop the weight loud sometimes, which I'm trying to improve). This nerdy "physical trainer", e.g. "magazine page flipper" came over and told me to be quieter. meanwhile, I have seen other people:
1) bench ridiculous weights with what I call the "bounce and spot tenchnique", aka "pectoral trampoline" albeit no collars, and sliding the plates off when they can't lift it...
2) same people with feet on the bench, no spotter, and 1/4 reps on the bench like it means something (I dont think they were doing X-reps, or like that, i think they believed were sincerely benching)
3) use the squat rack AND hack squat machine as a leaning post with an occasional few reps so as to continue their monopoly on the equipment I want to use
4) use of the chin/dip station for the same purpose, or clothes rack
5) WRIST CURLS in the squat rack!
6) people who walk sideways without looking in our very crowded gym with weights
7) deadlifts, cleans, squats below parallel, curls outside the squat rack, agnostics, athiests, and wearing sleeves are all dangerous.
