I never said appearance doesn't matter. It's obviously the no.1 factor. However, the no. 1 factor in appearance is your face, not your body.
If your face is handsome and your body somewhere within the average range, you'll be far more attractive than a guy with an ugly mug and a ripped physique.
I feel like this too strictly categorizes face vs. body, the way we do with women. With men, it's more of a sum of the two -- although I agree, if we're comparing a very handsome guy with a dad bod, to a pug-nosed disaster ripped like a Men's Health cover model, you're right. Some women prefer the more rugged macho man look, but I'd say at least 7 out of 10 will go for the pretty boy if both were presented purely in a vacuum (where their status, wealth, and personalities/game etc. were either identical or irrelevant). However, I don't think the comparison is ever that polar in practical reality.
In practical reality, most of us fall within the gray area of the pretty-ugly spectrum. Most of us posting on an attraction forum, that is. And for most of us Joe's, pumping iron and building a powerful, intimidating physique is something we can all easily control and optimize, unlike our facial aesthetics or our height.
And to add, getting in killer shape will improve not only your body, but your face as well. It will chisel up your cheeks and jawline. When combined with a haircut that tightens up the sides, this accentuates the chin and jawline and gives much more handsome, masculine appearance.
Although I believe weight/resistance/strength training of some kind is essential, to answer your question, no, it doesn't give you an advantage in dating.
It's just too easy to find endless examples of jacked guys who aren't getting laid.
See, this is like saying that wealth and status don't give you an advantage in dating, or being handsome doesn't give you advantage in dating, because we all know financially successful men and handsome men who can't get women. I certainly do.
However, unlike being 6'4, having a high 6-figure career and looking like a movie star, having a sexually appealing body is
readily attainable to everyone here reading and posting on this forum, and it
absolutely gives you an SMV boost-- I can't even imagine why, or how, anyone is going to argue with me on that.
