Lately I’ve noticed that most people with shorter clavicles tend to have rounder and bigger arms. An example is like Phil heath or Lee Priest (obviously these are extreme examples given that they have some of the best arms in history) . On the other hand, people with longer clavicles tend to have slimmer arms e.g. Big ramy or even the mens physique competitors. Is there anything occurring anatomically that makes happen or is it just coincidence?
