Yeah there's a middle-aged guy who stinks (BO) who pops into my gym occasionally who grunts on his 100kg 1/4 rep back squats after zero warm up.
he then wants to chit chat while I'm ignoring him and just getting on with my workout - I don't even take a phone to the gym because it's just workout time for me. Freaking annoying.
I'll admit that on pushing exercises I may hiss a little if I'm pushing out the last rep or two in a set, certainly not loud though.
A few interesting points you raised.
Im just tired of guys who stink at gyms, ffs buy a few outfits because its obvious you are wearing the same clothing multiple days in a row. It would be impossible to police fairly, but I wish gyms would tell gym users that they stink and to do something about it. Ironically a PT at the gym has one of the worst cases of BO I have come across.
Grunting, can piss off a lot of people and can also intimidate a few people.
Chit Chat. I have noticed old guys tend to do a lot of chats between sets. Not only that but if they happen to chat to you instead of a quick 45s to 1m comment, they break out into a long winded story. ffs I try to have as an absolute max, 45s rest between sets.
No phone. Period. FFS Going to the gym for me is a peaceful enjoyable experience where I can get away from everything in the world. I find it relaxing to not be disturbed or have the need to surf the net, facebook or message anyone.
