Meltdown. You supposedly outweigh me by 50 pounds, yet my forearms are bigger. 
Isn't forearm size mostly the result of genetics, like calves? I'm not saying one cannot improve what they have, but I have done hundreds of thousands of various types of calf raises and my calves still suck. The same is true for my forearms which hover around 13" no matter how hard I train them. I often see totally out of shape people with massive forearms and calves....go figure!
