Yup. To me, a muscled/fitness-type guy who seems to care too much about his appearance is a turn-off, I'd be unlikely to seek friendship. It signals to me "we share very little in common". Which, to be clear, is a prejudice, but if we're discussing physical appearance, that's what this is about.
Also, something similar happens with (some, not all!) guys being afraid to approach very attractive women because they seem out of their league. And the same must happen to some women.
