Men with muscles are unattractive

Nothing much to say here other than the fact that a slim man is much more attractive than a gym rat.

Science disagrees

The results show that most male bodily attractiveness stems from cues of formidability and physical strength, and that strength increases attractiveness in a linear fashion. The rated strength of a male body accounts for a full 70% of the variance in attractiveness. Additional variance (up to 80%) can be explained by adding the premium women put on height and subtracting the penalty put on additional body mass unrelated to physical strength.

TLDR: Height and muscles increase attractiveness in a linear fashion, meaning bigger is better.
