Lena Dunham turned a minor workout debacle into a major body-positive moment.

The Girls actress-creator shared a mirror selfie after she forgot her gym clothes while paying a visit to fitness guru Tracy Anderson for a Monday sweat session.

"Late to @tracyandersonmethod & forgot my workout clothes so had to snag a size large bra and size small pants (wrong in myriad ways)," the 29-year-old captioned a shot of herself wearing a borrowed black sports bra and some funky printed leggings.

"But do we soldier on? Yes, yes we do because we want to be a strong & happy lady," she wrote in the post.

Dunham has been dedicated to her new health regimen. And for the star, exercise is much more than looking good.

She shared her newfound fitness philosophy on Instagram last month, writing, "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."

"It ain't about the a—, it's about the brain," she added.
