I'm new to all this and so I can't see why people are arguing. I get a lot of approach anxiety, so I've approached very little. Until I read the game I hadn't even considered that approach is a specific thing. It was all just merged.
When I started working out, I got leaner and a better shape and got many more looks and eye contact. I'm not big and well muscled, but I'm not so fat anymore.
I reckon your body is an advert composed of several things; the body, body language, the clothes, grooming etc. If your advert is good, they will want to meet you more. Whether this gets you laid or not, I can't answer. I'm on a drought, but it got me more attention. Surely it has to count for something and so a better looking body (don't read massive, just better looking) has to be a benefit.
The guys that are like wizards with openers could even use this as one... "do women prefer muscly or chubby guys..." or something along those lines.
I recently read the "Adonis Effect" and the guy was quoting research that there was an 'ideal proportion' for attractiveness. Again this could be fake research to sell his book, but it seemed genuine to my untrained eyes.
I found a torrent for it somewhere. I don't know the rules here well enough as to whether I can post a link to the site or even the torrent, so I won't, but anyone who can make google work can look it up. The sales blurb tells you all you need to know as far as this subject goes so you don't even need the book.
It come down to a simple formula and for the record I think it was; measure around the shoulders and it needs to be 45%-47% of your height and shoulders need to be 1.618 x your waist.
