The Physical Demands of Filming The Hunger Games Sequel

The ever-present paparazzi have caught Jennifer Lawrence in work out clothing again:

Climbing trees, hand-to-hand combat, weapons wielding and a lot of running -- the physical rigor required of the actors on the "The Hunger Games" series is enormous. It's no wonder some of them have been spotted working out, likely in preparation for the film's sequel, "Catching Fire" -- set to start shooting in mere weeks.

Maybe she just has a life? Perhaps that's why she is out doing whatever she wants?

I'm getting ready for the next round of stories about how the actors are being injured on the set. The Hunger Games is one of the most physically demanding movies being made this year. Couch potatoes need not apply.
