You don't get that with the high intensity training like Crossfit where you spend maybe 70% of the time working out and 30% of the time dying.
The gym is not inherently social unless you are actively spotting / alternating uses of a single machine. You either join that group of gym rats (who in my experience spend 80% of their time talking) or you put your headphones on and crack on solo.
Its a great space to meet new people, there are inherent breaks in the activity, shared problems to work on, and its a non-competitive space. Everyone just wants everyone else to send hard.
I had like 20 years of social anxiety and it’s actually very anti-climactic when you can have a normal short conversation with a stranger. Not dramatic and no one’s traumatized
- new climbers asks you for advise
- you can ask a new climber if they'd like some technique tips
- you finally top your project and someone commends you for it
- someone tops your project and you ask them for advise
- you're trying to top a boulder on a new set and are solving it with others
- you're _constantly_ in the gym so staff starts talking to you
A lot of people on their own have earbuds in too,and clearly don't want to be spoken to.
I had one time where I asked someone for some help, he then went and did the route and shrugged and said it's easy in a really condescending manner.
I generally have a hard time connecting with people like OP but found that I was able to find good climbing partners outside as opposed to in the gym.
I now do crossfit and while I know it's not for everyone, it's a decent community. I still don't talk to folks in the gym, I don't want to but I like that we're all in it together and pushing ourselves pretty hard. I feel connected in that way.
I would really not like a stranger tapping me on the shoulder in the gym. That's my "alone time". That's just me though.
I find it highly strange to assume malicious intent ("flexing"), rather than charitable one (they're just interested in this route regardless of you being on it, or your attempt made this route seem fun/interesting and made them want to try it for themselves).
People seem to assume bad intent all the time when there's obvious equally-or-more-likely charitable explanations, to the point that I wonder if it's me who's naive.
If someone jumps on something I'm struggling with, I take it as an opportunity to really pay attention to what they're doing and try to learn. They might just be way stronger, but they probably also have some better technique ideas.
For #2, I just take it as a slightly awkward attempt to reach out and socialize. Advice isn't harmful. At worst it's a mild spoiler (oh well), or just wrong (then ignore it). At best it's a great chance to learn something.
I'm awkward and it's rare for me to start a conversation, so I just take someone else talking to me as an opportunity to connect without having to make the awkward first step, and try to spend a minute or two (at least) talking with the person.
I'm lucky enough that I live in a city that has a newbie-friendly group that climbs every week and goes for dinner and board games afterwards.
I consider myself an introvert, but after going for a while, I got to figure out who are regulars, and they recognise me as a new regular too, at which point they're more open to socialising more, even outside the weekly meetups.
Even when I'm bouldering alone, I've had random people cheer for me when I'm about to send, or show me the beta for a route I'm struggling with, or ask for help with a problem. It just provides a very natural conversation starter, at which point you can pivot to other topics, provided they seem open to talking more.
