The Oscar-nominated Winter's Bone star told Digital Spy that she sustained damage to her spleen during the making of the action blockbuster.
"I was pretty good, I didn't really do much. I bruised my spleen by running into a wall really really hard, but other than that it was pretty good." said Lawrence.
The Hollywood Reporter revealed that Lawrence had to undergo a CAT scan to see if her spleen was still intact. Her injury came on the last day of a six-week training course when she practiced running up a wall to gain momentum.
Asked about the physical aspects of playing Katniss Everdeen, Lawrence added: "I'm a pretty good tree climber, I really like climbing trees.
"Most of my tree climbing was done with a harness so if I tried to do it in real life I wouldn't be so great. I wasn't like 'No, if Katniss can do it, I can do it'."
