Renee Zellweger is a busy lady, but she makes time to hit the gym six days a week. However, she says it's not necessarily to stay fit -- it's because she uses it for therapy.

Zellweger says, "The gym is my therapy. I've got to get stuff out. The perk of going and spending time by myself and getting my head straight and thinking through what might be bothering me is that I get fit. That's not the goal, but it's a nice by-product."

I don't know -- I'm sure she gets some great mental benefits out of her workouts, but I'm pretty certain she's intent on burning calories, too. That girl is awfully thin. However, I'm sure many of us can relate to using our workouts as stress relief -- I definitely can. How about you?
