Earlier this week, "Girls" star Lena Dunham posted a "workout selfie" on Instagram along with a powerful message about the importance of exercise, especially when it comes to mental health.

"To those struggling with anxiety, OCD, depression: I know it's mad annoying when people tell you to exercise, and it took me about 16 medicated years to listen," Dunham wrote. "I'm glad I did. It ain't about the ass, it's about the brain."

Dunham isn't the only celebrity who wants the world to know she's a fan of exercise. From gym selfies to scenic hikes, these famous women are all about getting their sweat on.

While Dunham preached...
Karlie Kloss went for a jog in Paris.

Actress Jessica Alba showed off her toned arms ...
