What differentiates an Olympians arms?

I went to my country's nationals just yesterday, and in the over 100kg (225lbs) there were some big guys, but all lacked fullness and "roundness". But the most discerning thing to me is how, compared to the olympians, they have small arms. Their front double bicep shot made it look like they had 18inch max - and side tri and side chest was almost a joke.

What is it about the top guys that made their arms as big as they are? Literally just the years and years of building them up?

Olympians are the best bodybuilders in the world. So of course theyre going to be top notch.

slin, GH, synthol, genetics and a lot more hours in the weight room (they do it for a living unlike those guys you saw who have real jobs). thats why they are freaks and frankly i much prefer the look of the old style bodybuilders and if you ask your gf she will agree.
