I am blessed with very large traps and neck. When I'm lean, they look pretty impressive. they are definetely comparable, size wise, with some juicers i've known.
I have a friend with monster calves. he's all natural, and they are just insane. again, genetics... but they look like a juicers calves.
I have another friend who has ridiculous forearms, all natural, juiced look though.
I don't know anyone with juiced looking quads, back, chest, bis, tris etc...
so, why is it that there is a genetic disposition to being able to build muslces like the calves and forearms naturaly (or neck and traps) to levels that other muscles seem able to attain only with roids? Are we training wrong? is there something to learn from the high volume??
