When Lena Dunham took to Instagram a couple of months back to tell the world she had realised exercise was a better cure for her anxiety issues than medication ever could be, we knew there were changes afoot for the actress/writer.

Now the Girls star has revealed that she's loving her fitness routine even more, after a friend encouraged her to go to a running training session. Posting a paparazzi photo of herself running through the streets of New York to Instagram last night, Lena wrote, "Not usually one to post a paparazzi shot but this fills me with pride. Basically my whole life I have hated running and run like a wounded baby Pterodactyl."

The actress said her fear of running was "embarrassing" and joked that she didn't trust herself to "escape a burning building or even move briskly towards a buffet." However when Girls' executive producer Jenni Konner suggested that Lena's character Hannah Horvath develop a love of running on the show, the real life Lena had to follow suit.

"@jennikonner is directing the season finale of Girls and decided that as Hannah evolved so would her run, so she got me a training session with Matt Wilpers from Mile High Run Club. Within an hour I had a different relationship to this formerly torturous activity. I felt strong, swift and proud," the actress wrote.

"I'm not about to embrace that triathlon life but it's a true joy to continue getting more connected to my body and its powers." 

Although she still maintains her curvy frame, Lena is looking fitter and more toned than ever, and nowhere is that more apparent than in the papped running shot. After all, how many of us can say we'd look that put-together in a candid shot of us running down the street in our workout gear?

As well as jogging, Lena is also an advocate of celebrity trainer Tracy Anderson, and often works out at her New York studio, saying Tracy's workouts have shown her "the light."
