Those Manolo Blahniks were made for running, and that’s just what Sarah Jessica Parker did.

In preparation to reprise the one and only Carrie Bradshaw for the big-screen adaptation of Sex and the City, the actress admits she had to do some pre-filming training.

"I did consciously work out for a few months. I wanted to be able to run in heels," Sarah tells Extra. "While it may seem easy, if you haven’t done it for about four years, it’s actually harder than it might appear."

One thing that was easy though — slipping back into those stylish clothes.

"I will try on anything for [stylist] Patricia Field," she says. "I will try on anything for her. I am her own personal monkey. Her own personal paper doll."

As for her colleagues, the 43-year-old was excited to reunite with all of them, especially Chris Noth, her Mr. Big.

"I can’t say enough about what Chris brought and how much he enjoyed being there and how much he wanted to be there," Sarah says.

The film revolves around Carrie and Big’s upcoming nuptials, and while Sarah says Carrie doesn’t necessarily believe in "happily ever after," Chris does drop one hell of a spoiler about the cinematic duo’s future.

Asked if Carrie and Big will ever have children, Chris responded, "Oh, absolutely."
