Gwyneth Paltrow Whips Her “Sagging Ass” Into Shape With Tracy Anderson Workout

Celebrity trainer Tracy Anderson is helping screen star and mother-of-two Gwyneth Paltrow give her bum some pizazz with a regular regime of grueling exercise. The 37-year-old Oscar-winner posted a video of the trainer’s Little Arms Series,” which Gwyneth used to rid herself of “batwigs” while preparing for the superhero action flick Iron Man.

“She has kicked my formerly sagging ass into shape, and I will be forever grateful,” Paltrow wrote of Anderson on her often lampooned lifestyle site Goop.com this week. “Many of you may already know of my passion for the Tracy Anderson Method and my investment in it…..This week, Tracy shares with us a little arm series that I did everyday preparing for Iron Man and that I take on the road. She just made it home-made style for me, lo fi. But it’s good. Especially for the batwing problem. Also, some of her dedicated clients talk about why they love her as much as I do. She has some brand new DVD’s that I have been doing in my hotel room on location and which I highly recommend….”

Best known as Madonna’s former personal trainer, Tracy Anderson has worked out with celebs that include Jennifer Aniston, Courteney Cox, and Kate Hudson.
