Actress Lena Dunham says she has turned into a fitness freak now partly because of her recurring breathlessness and for her "exercise" loving parents.
"Part of the reason I wanted to do it was I was losing my breath when I walked up (a) stair," the Girls star, 28, said on "Late Show With David Letterman".
"And also, both my parents, who are 65... They're both really exercise fiends. They look really hot, and I was just starting to feel like I was really dragging behind, and I was like, "You're more than twice my age and I look like a bag of trash next to you.'"
Dunham has been doing "a variety of things" as a part of her new "physical fitness kick," she told Letterman.
