Lawrence used a variety of workout techniques to prepare for this physically demanding role. She told MTV News that the training was fun. “I’ve been doing archery, rock climbing, tree climbing, combat, running, and vaulting for six weeks. But also yoga and other things, to remain catlike.” Lawrence almost had a production delay when she hit a wall on the final day of her six-week training program. Lawrence told The Hollywood Reporter that she hit the wall with her stomach when she ran towards it. “My trainer thought I’d burst my stomach. I had to go for a CAT scanner and get into a tube with a fiery liquid.” Lawrence, despite being bruised and with no broken bones, was able to continue filming. Hutcherson trained heavily before filming. He told Collider, in 2012: “I had never done that for a film.” I gained 15 pounds, which was mostly muscle. It was also a high-protein, low-carb diet.” As for Hemsworth, he revealed his older brother, Thor‘s Chris Hemsworth, offered him some surprising advice to prep for the movie.“My brother texted me before shooting and told me to lose weight,” Hemsworth revealed to The Hollywood Reporter
