Call off the arms race: if you’re still obsessed with your biceps and triceps, you’re putting yourself at a disadvantage in the dating war. In fact, if your workouts are mainly focused on the muscles you see in the mirror – including your pecs and abs – you may as well start waving a white flag. 

Why? Because when it comes to attraction, a body that’s ready for action in the running, fighting, saving-cats-from-trees sense gives off visual vibes that you’re an evolutionarily viable catch. According to one study from the University of Windsor in Canada, for instance, how attractive men were rated by the opposite sex correlated almost perfectly with their shoulder width and upper-body taper – or how close they were to the V-shape that signals functional upper-body strength. Think classical statue, not Austrian bodybuilder – proportionally, Michelangelo’s David is close to the ideal masculine shape.
