Thread: Target different points of a muscle?

I have a PT at my gym that is shredded to the bone and he claims there are exercises/variations to target different points of a muscle, most commonly showing exercises which makes the line between muscle separation more noticeable e.g.separation between shoulder and triceps/biceps. Is this true?

Came in to say this pretty much.
