What attracts women most is a man with an inverted triangle like an athlete. An athlete's strong figure is a sign of good health, which shows that he has the ability to catch food and drive away the enemy. Even in today's era of advocating equality between men and women, bulging biceps and broad chest are of little practical use, but they can still stimulate a woman's brain when evaluating a suitable partner. Inverted triangles are still attractive to women, because women's bodies belong to regular triangles. Where women's body curves are plump, soft and boneless, they are often also places where men are angular and strong. It is this difference and complementarity that attracts women.
Broad shoulders, chest and muscular arms are also important. Broad shoulders are characteristic of men. Women who want to defend their rights often imitate this feature. They put their hands on their hips to make their shoulders look wider and take up more space. Professional women look more confident wearing shoulder pads. Shoulder pads act like epaulettes worn by men. Men's arms are longer than women's. Long arms make them good at aiming and throwing, making them better predators. Men with symmetrical upper body are easy to attract women, but most women don't like "muscular men", that is, men in the shape of bodybuilders. They think that such men appreciate their beauty far more than they pay attention to the opposite sex. Women appreciate healthy and energetic men, but for Arnold? Schwarzenegger-style men are daunting.
Men can make some appropriate changes to themselves according to the type that the other half likes.
