I get the information on my site from various sources including (but not limited to): musclememory.com, repetrope.com, all pro websites, and from my huge collection of bodybuildings mags. Plus I ask on ironage how tall pros were during their prime all the time.
The general consensus for Darrem is that he is about 5'8 or 5'9 at 230-235. Probably closer to 5'8 actually so maybe I should change that file.
As for Arnold, try to keep in mind he was all chest and arms. Compared to pros today he was lacking everything from behind except for calves (e.g., back and hamstrings).
And before the ironagers start pulling out pics of Arnold from behind looking big, keep in mind he is standing alone in those pics, and keep in mind I'm not saying he is small from the back, but the objective reality is that he is small from the back compared to pros today. Pros these days are thick from head to toe (including midsection too, I don't deny that).
Re: pros whose muscles don't "pop" when they flex. That is because people like Markus Ruhl and other pros today are so damn big to begin with that their muscles can't pop. They are already popping all over the place even when standing relaxed.
