I notice many PUAs tend to say that women are impressed by men having cool hobbies. Like action sport (or sport in general), keep fit, etc.

I don't get this reasoning, in honesty. I think labelling some actions as cool or nerdy are just arbitrary social labels, created by pop culture/mass media. There is nothing that makes action sport inherently better than reading books for fun. That said, it seems that PUAs are tailoring men to be attractive to a specific type of woman, who is very trendy or "with it".

But aren't all women different? Do all women everywhere find enjoyment in cool or trendy pursuits? My conception of PUA is that it should be able to attract any woman. It's basically a set of techniques that rely on how women think (and human beings in general) to pick up/score, etc. If PUA can work on picking up a woman who likes to club every weekend, then it should also work on a woman who likes to go to the beach a lot and hates clubs with a passion.

just treat all you hobbies like ther cool.
if you feel the girl may think that a particular hobby is "nerdy" in a bad way neglect to mention it.
i have had some hobbies that most people would hide get me some attraction built because i look them in the eye and say "have you tried it?" then i treat it like coffee, "you dident like coffee before you tried it out to see if it was good so how can you say that about anything else"

Don't think whether your hobbies are going to impress a girl or not because you do not choose your hobbies for them.

It's all about the passion. You can be a stamp collector. If you speak of it with enough passion it's doesn't really matter what you do.
