The 16 year-old actor says, "I started working out the day after I finished filming Twilight because I knew it was a necessity for the character.
"I put on 20 pounds," he adds, then promised the producers another 10. "I've already put on about six. So, four more pounds and I'm a man of my word."
He did it by eating muscle-building foods and spending several hours in the gym, 7 days a week.
"I basically killed myself."
