As if anyone needed more proof that Jennifer Lawrence is tough as nails, check out this EW exclusive clip from the special features of the Blu-ray/DVD ofThe Hunger Games, where viewers can take a behind-the-scenes look at how Lawrence trained for Katniss, and why the crew made her her own climbing gym.

Inside scoop: The knots on the tree in her training gym became the same as the ones in the movie so Lawrence could accurately practice her climb — complete with a harness, of course.
