Josh Hutcherson Hits the Gym for Catching Fire!

Fans are gearing up for Josh Hutcherson's return in the Hunger Games sequel, Catching Fire, but no one's as excited as Josh himself!

He's gotten so into the role that he's completely changed his eating habits and fitness regime. He's switched to a protein-rich diet and packed on 15 pounds of muscle, and he's also been training with a NAVY seal alongside costar Liam Hemsworth!

"After the games, Peeta would have been taking care of himself physically," Josh told USA today. "And he's gone back to the village and is able to eat healthy. So I've been training and getting ready for that."
