Lena Dunham appeared visibly slimmer when appearing at the opening of personal trainer Tracy Anderson's Flagship Studio in New York earlier this week.
Sporting a grey singlet and colourful, printed leggings, the Girls actress posed for photos with her trainer Tracy, who has also worked with the likes of Gwnyneth Paltrow, Jennifer Lopez and Victoria's Secret model Alessandria Ambrossio.
For Lena, her fitness regime with Tracy has been more about developing strength as opposed to shedding the kilos.
"I think for me the big thing was that Tracy just very clearly wasn’t trying to change my body," she told People at the store studio opening on Wednesday.
"I came to her and was like, ‘I have endometriosis, I have chronic physical pain, I just want to feel stronger I just want to have a stronger core, I want to feel like I have more power throughout my day, how do I get there?' I like that she was coming at it from that perspective rather than like, I’d like to shrink six inches…"
Lena's change in appearance has not gone unnoticed, and the actress herself has addressed the coverage her transformation has received in the past 24 hours.
Taking to Instagram, she reiterated that her increased exercise regime was devised for her endometriosis, as opposed to any weight loss goals.
"I've gone on red carpets in couture as a size 14. I've done sex scenes days after surgery, mottled with scars. I've accepted that my body is an ever changing organism, not a fixed entity- what goes up must come down and vice versa," she wrote.
"I smile just as wide no matter my current size because I'm proud of what this body has seen and done and represented. Chronic illness sufferer. Body-shaming vigilante. Sexual assault survivor. Raging hottie. Just like all of YOU.
"Right now I'm struggling to control my endometriosis through a healthy diet and exercise. So my weight loss isn't a triumph and it also isn't some sign I've finally given in to the voices of trolls."
