While speaking to E! News about the superhero flick, the 31-year-old House of Cards star said that she "hasn't been told anything specifically" regarding her training routine for the film.
"But that could change once we start filming," she promptly added.
As for having to wear those tight Spandex suits, Mara said she's not sure that the film would feature Spandex outfits at all.
"I don't know that that's a thing," she said. "I think our film is going to be very different than the other one, which I never saw, but I know there was a lot of Spandex involved. I don't know that they're many Spandex suits in ours."
The reboot of the Marvel film is expected to hit theaters on November 19, 2015.
