When Gwyneth Paltrow gave birth to her second child, Moses, she turned to one person to help her get body back -- Tracy Anderson. (Though in Gwyneth's case, I'm not sure she ever lost her body. Have you ever seen an ounce of fat on that girl?)

In any case, it was a partnership that changed both their lives. Gwynny got her post-baby body firmed right up, and Tracy's honing her trainer-to-the-stars reputation. Luckily, you don't have to be a star to learn from Tracy, though. She's got a collection of fitness DVDs, including a new one for post-partum moms.

Tracy Anderson recently talked to Cookie about her own hot-mom secrets. Here are some tidbits:

Tracy's Method: Tracy developed her own fitness method -- which involves light weights and high reps -- after gaining weight in college.

On Food: Tracy loves to eat and thinks it's healthy for her kids to see her do so. "It's healthier for them to see that (dig into a birthday cake) than to see Mommy counting her Weight Watchers points," she says. "I think that's the worst thing we can do to our kids."

Trainer to the Stars: Tracy actually lives and travels with clients Madonna and Paltrow while training them. Her son Sam, 10, and his dad come along too.

Got some baby weight to lose? Cookie says Tracy's DVD will not only whip you into shape, but she's strong and supportive too.
