My uncle has stooopid crazy popeye forearms. So good, that I few months back oli asked him what does he do for them. He said, nothing really. He said used to lift weights 30 yrs ago, but stopped. He is always doing mechanical work of some sort. And for a black guy to have such huge forearms, without working them is rare. Same for my dad. He is 5'11, and has high calves, much like Flex Wheeler's, but they are pretty damn big, 19"s, but he never trained them. He grew up on a farm, and he used tell me about lifting 100 pound sacks. When he was younger, he had what I call "dad arms", big round arms, with big forearms.
