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."
