I mean, you can’t just get fit and expect someone to come knocking on your door. If you are feeling good about your looks now, that’s an accomplishment you can be happy about, and should, but it doesn’t send out some secret signal that you are ready for a relationship. You have to talk to actual people. You can meet them out in the world or on an app, you can also tell any friends you have that you are looking to start dating, network. I think friends of friends and dating apps are the most usual ways of getting dates now. When I was young we just hung out in groups and some people always people ended up paired off, didn’t really date per se, but my kids don’t seem to do that as much.
So basically - now you are happy about your physical shape, you still have to reach out to people, that is the next step.
You are talking to us here, now. I know you do rock climbing and weight lifting. If you have friends, you talk to them too. It’s not different from that. You are doing it already. There’s not a formula.
What friends can do is tell their friends you are a great guy and introduce you to other people. That’s what networking is, the same way you network computers, you network human relationships, by connecting them.
