Gwyneth Paltrow In 'Self': In A Bikini, Talking Butt, Food, Juicing (PHOTOS)

A bikini-clad Gwyneth covers the new issue of Self magazine and inside she talks all about her body and what she puts into it.

Self's press release follows; scroll down for photos and learn how to do Gwyneth's workout moves here.

On her challenge areas:
"My butt! My butt, butt, butt. When Tracy met me, she said that I had a long, square butt that she was going to redesign, and I was, like, "Yeah? Good luck." The amazing thing is, she was right! And it's still changing!"

How she stays sane about her body:
"I've found what works for me. I know if I put in an hour and a half, five days a week, I'm good. If I'm on vacation and, like, "F--- it, I'm not working out," I know what to do when I get back. A lot of women think, "Oh, my God, I could never get there," but I don't think that's true. It's simply relative to how much you put into it."

How consistent she stays, foodwise:
"I say I always eat right, but last night, I had fried clams, pasta with duck sausage and two glasses of red wine. When I want to lose, I eat less pasta, bread and potatoes. Before last year's Iron Man 2 premiere, I did green juices and salads for three days."

Gwyneth's fitness secret:
"I do 45 minutes of cardio five days a week, because I like to eat. I also try for 45 minutes of muscular structure work, which is toning, realigning and lengthening. If I'm prepping for something or I've been eating a lot of pie, I do two hours a day, six days a week for two weeks."
