Most of females are into the types of Brad Pitt and David Beckham, who are definitely fit, but thin (Beckham is outright scrawny, Pitt used to be "cut" when he was young, not so much now)
So definitely the "left" type. A lot of women say they are intimidated by too much muscle.
These sort of statements are misleading - women who are more physically attractive (unfortunately, what most males prefer) tend to prefer the model on the right (in my experience).
