No, the rhomboids are visible and my brother, who is an M.D and also a bodybuilding fan, told me tt this is one of the major ingnorances popular among bodybuilding fans: that the you can't see the rhomboids because they're hiden when relaxed.
Nope, the rhomboids are not visible.
My laboratory professor had a Ph.D. in Neurobiology & Behavior from Cornell University, M.A. in Biology from the University of Oregon, and B.A. in Zoology from UCLA. My professor in lecture had a Ph.D. from the University of Tennessee.
I have seen this fact firsthand (i.e. cadavers), in scholarly publications, my textbooks, lectures, etc. You insult my intelligence by defending your post by merely citing that your brother is an M.D. First off, I doubt that your brother is an MD. You are notorious for making up bold lies.
Most likely you are just attempting to cover your ass for making a stupid mistake and this is what you come up with. Whatever.
But I'll give you the benefit of the doubt on this one.

He is an allopathic practitioner, no? You should know that MD's do not have the same grasp of anatomy as the leading PhD's in the field do, primarily since anatomy is of secondary importance to MDs. Most are concerned primarily with pharmacy and medicine.
Until this "brother" of yours comes up with something concrete to refute my firsthand experience, as well as the testimony of credentialed, highly qualified university professors, I'm going to completely ignore this defense because it is a waste of time.
If you are willing to take an M.D.'s word over an entire university's science department, consisting of respected Ph.D's in anatomy, physiology, biology, etc. then you are retarded.
This isn't something to debate suckmymuscle. The rhomboids aren't visible. Admit you are wrong and move on. This is simple science here, we are no longer in the realm of opinion and intangibles that have defined the past 300 pages of this stupid thread.
Guess what? When you flex in the back double biceps pose, they slide and you can see them. And don't try to discredit me saying that you learn this in the first year of physiology in college, because you don't know shit about the subject. I almost gasped when I read your analyses about Ronnie's quads; amazing that someone can say so many stupid things at once. 
No, they don't slide moron. You are making this shit up as you go along.
They are hidden under the trapezius, which is a massive muscle complex.
You are 100% wrong. I've already graduated from university. I used the introductory anatomy course as a reference to attest to the fact that it is YOU who doesn't know shit on this subject.
My point was, even the freshmen would learn in the 2nd semester that you are wrong, so obviously you don't even have 1 full year of science from a real university under your belt or you wouldn't have made that mistaken assumption to begin with.
I'm not even entirely sure you have a college degree (although now I'm sure you'll claim you're a Ph.D. in some inane subject just to try to one-up me, as you always do), and if you do, its obviously not in the life-sciences.
Lastly, the quadriceps debate had nothing to do with science prick.
I knew the 4 muscles of the quadriceps (vastus lateralis, vastus medialis, rectus femoris, and lastly the vastuls intermedius - which is not visible but hidden under the rectus femoris). The rest of the debate pertained entirely to striations, the shape of the muscles, conditioning, preference, balance, etc. etc. i.e. ABSOLUTELY NOTHING TO DO WITH SCIENCE.
You try to discredit me by telling me my defense of Ronnie's quadriceps was poor?
Stop bringing up irrelevant shit in a misguided attempt to discredit me.
Our Ronnie v Dorian debate is irrelevant now suckmymuscle.
Fact is, you made a statement that is anatomically impossible UNLESS DORIAN HAD A LARGE PORTION OF HIS TRAPEZIUS SURGICALLY REMOVED.
This has nothing to do with the difference in our tastes and preferences, but with scientific fact, and in your case, scientific ignorance and error.
Just drop it. You are only embarrassing yourself.
