It seems these days all BBs have massive delts, which often make their arms look smaller than they are. I used to have no delts, but after years of heavy dumbell presses amongst other things, they have become a strong point. Which makes me think that I was not genetically gifted yet still built them up. Calves are harder to build, and it's rarer and more exceptional if someone has big calves. For some reason I just can;t be arsed to train them though, but only out of laziness, not because I'm convinced myself that heavy presses are somehow linked to being genetically amazing, when in reality chest and shoulders are just easier and more fun to train. That's why everyone has good shoulders and no-one has good calves. Case closed.
