Every time I go to the gym there are people who sit around on machines for ages between sets , scrolling on their phone or whatever, as if no one else in the gym needs to use that machine. I always get up between sets in case someone else wants to use it or go between machines. I sometimes politely ask if I can do a set while they’re not using it , people usually say something like “ I’ve got two more sets to left to do” occasionally someone will begrudgingly get up looking miffed. On rare occasion someone has been aggressive towards me. My gym aren’t interested in fixing the problem with signage about gym etiquette. WWYD?
