He just cut carbs. Ive seen the guy in real life... he is a twig. The movies just make him look somewhat jacked. Movie tough-guys like vin-deisel and others really aren't very big.
Grantie54strong- change your name to "I'm a little bitch" if you think that somebody nedds juice to look like that you are seriously mistaken. I was bigger then that when I was 17, not a word of a lie. He is no more then 150-160lbs, what the hell is that? That's not much bigger then a feather weight boxer.
I gotta agree with Tx longhorn, that actors or most people would take the easy way out and juice in place of exercising with insane intensity....when you get paid on having low bodyfat, why not juice? Most of us juice and dont get paid anything!
What made you come to that conclusion, he's puny? Anybody can lose fat, all you have to do to look like that is eat about 2000 cals a day of clean food. You'll be scrawny in no time.
