I can't speak for every woman, but I can speak for my own experiences and report based on the things women I know have said. For me and those I've spoken to, we may like muscles, but the things you need to do to get those muscles often aren't as attractive and cancel it out. Like, if you're getting muscles by going to the gym every day, that's only gonna attract women who are enthusiastic about the gym. If you get them from farm work, you'll attract women enthusiastic about farm life.
That's why a lot of us like dad bods so much. It's not that it's inherently more attractive, it's that it's a body type achievable by living the kind of life style people who're into that enjoy.
In other words, yes, muscles can be attractive, but not nearly as attractive as shared hobbies and interests, and it just happens quite often muscles can be a quick indicator that you probably don't share many.

You’re close. The real truth is that most average people do not like to date too high above their perceived range of attractiveness. This bears out in many studies but people are attracted to 8’s and 9’s but won’t date them and instead mostly date people that are more normal 5,6,7’s.

Then we look at the opposite side of the coin, 9’s and 10’s don’t even want to date each other. And for good reason. Extremely attractive people often cross a line into narcissism or being too busy to hold a relationship.

So two factors: 1. Most people aren’t extremely fit and so don’t want to date people whose lifestyle does not match their own, we’re all also slightly insecure. 2. Extremely attractive partners tend not to be good partners. The more people that are attracted to you, the less that date you. Also that’s out of fear of competition and effort so it’s not worth it.

Yeah, I think in general it starts with trying to impress women, then you do it to impress other guys.

I guess it’s similar for women, they might get into doing their make up and looking nice for attention from guys they like, but in the end they’re mainly trying to impress other women or just doing it because they enjoy it.

People usually like the physique, not the commitment it needs to get there and maintain it. Plus, the steroids.

Lots of women like really jacked dudes (and many gay men of course).

I don't like super lean jacked dudes personally. Give me a big thick rugby player or a 125Kg sumo wrestler any day over a bodybuilder.
