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…

Promised myself I would not let exercise be the first thing to go by the wayside when I got busy with Girls Season 5 and here is why: it has helped with my anxiety in ways I never dreamed possible. 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. I’m glad I did. It ain’t about the ass, it’s about the brain. Thank you @tracyandersonmethod for showing me the light (and @bandierfit is where I bought my Florida mom inspired workout look.) #notsponsored #stillmedicated
