Reese Witherspoon gym brentwood blonde sunglasses bottled water yoga pants

Reese Witherspoon hit the gym early on Tuesday morning, and we're thinking the fact that her sports bra and sneakers are both purple isn't a total coincidence...

And speaking of working out, it sounds like the Oscar winner had to get in pretty killer shape for her role in the upcoming film Wild. Director Jean-Marc Vallee chatted with Entertainment Weekly about Reese's transformation for the role (“She went method with the hair and no makeup," he says), and he revealed that she also had to get comfortable hiking all over the place with a heavy backpack, and she even had to learn how to pitch a tent!

The film follows the story of Cheryl Strayed’s journey along the Pacific Coast Trail, and though the film was shot in a mere 35 days, Strayed's hike was 1,100 miles and took 3 months. Very curious to see Reese in this role -- it's definitely a departure from everything else she's done!
