No.
Just.

Bara doesn't mean muscles. It just means gay.
Literally it means "Rose"... and it comes from one of the first gay magazines in Japan: Barazoku (Rose Tribe).
If it's made for a gay man, it's bara. Period.
Your example is still bara, it's just that one of the characters is coded "straight" and thus is "attractive" due to him looking straight but being gay.
The form the characters have isn't what makes it bara or yaoi, it's who the intended audience is.
Generally speaking, bara works will be muscled and yaoi will be effeminate (by western standards) but that's because those are the stereotypes in Japan for gay and straight respectively.
(Think of it like how lesbian porn for straight men usually lacks "dyke" lesbians and tends to feature only "lipstick lesbians". It's the same thing.)
