Bale put on 100 lbs. in like 12 months. It's not that hard when you've got good trainers and a work ethic. I'm fairly confident Bale didn't juice, he basically got back to his normal weight then added about 35 lbs. If you look at him in BB, he definitely doesn't have the roided look (super veiny), he looks like he has some body fat (not a gripe at all, btw, just further proof that the dude ate like a beast).
