Gwyneth's Butt-Blasting Move From Trainer Tracy Anderson

Gwyneth Paltrow has said that she credits her fitness trainer Tracy Anderson for getting her "sagging ass into shape." Harsh words for her tush, yes, but if you want to tone your rear, this video, courtesy of Tracy, shows you exactly how ...

Gwyneth Paltrow loves her fitness trainer's tough love (but maybe Madonna doesn't--apparently she dropped Tracy Anderson recently, noting that she was a "distraction"--hmm): "Every once in a while she sends me a little movie to change something up," Gwyneth wrote. "She sent me this one for the New Year's butt. It's really hard. But do it like she says to do it, and I swear that in ten days you will see your butt change shape. I do it with 1 lb. ankle weights and then I do her Dance Aerobics DVD. Some days I hate it, some days I love it, but above all, I stick with it. The sticktoitivness is what it is all about."

(Love "sticktoitivness," which is my current motto for getting out there for a daily jog--even if it's just a brief one.)
