They have always naturally been bigger. They arent freakishly huge as i am not a freakishly huge guy I dunno i havent measured them. But they are much bigger than anyones I know. I do squats deads, extensions, curls, calf raises. Typical shit. Ive dont train them year round by any means. I woud just like to see them be proportional to my body. When im not lifting i do kickboxing and grappling, mixed martial arts stuff. That shit only makes my flexor muscles swell up nothing significant.
