no, it's not a well known fact. I've heard Ronnie's triceps are thin but never short.
Ronnie's triceps are thin in the lower part of the muscle because they attach high in the tendom. Your argument is redundant.
Dorian's triceps look better in the side triceps b/c the lateral head is thicker.
No, Dorian's triceps look better in this pose because they attach lower in the tendom and, thus, have better shape. This is fairly obvious.
It's obvious you don't have a clue what you are talking about. So you result to making shit up and ad hominem attacks.
This coming from the person who applies different standards to bodybuilders and posts photographic comparisons that show the extreme polar opposite of what you're trying to prove. And ad hominem? Did I make any ad hominem attack on you? When? Where? Do you even know what ad hominem means?
