dude... Do your research! These are the physical traits of a person with a high level of testosterone. That's what makes strong babies. Women love their babies, ie they want them to be strong and healthy. Does that make sense?

Basically, when you learn PUA and alpha body language etc, you are adopting/mimicking the actions of a high-T male. This is the way he acts naturally because his hormones drive him to do so. They also make him good looking as an evolutionary advertisement for the healthy genes that he possesses. Beauty is synonymous with health, fitness and strength. Is it a coincidence that most of the best athletes are also incredibly good looking?
