Gwyneth Paltrow Enlists Tracy Anderson To Fix Her 'Batwings,' 'Sagging Ass'

Now that Gwyneth has detoxed, she is shedding her batwings with the help of celebrity trainer Tracy Anderson, who has been engineering her workouts for years.

Gwyneth writes in her newsletter GOOP:

Many of you may already know of my passion for the Tracy Anderson Method and my investment in it. She has kicked my formerly sagging ass into shape and I will be forever grateful. 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.


Tracy was also Madonna's trainer until last fall, when the two had a dramatic falling out. Below you can watch a video of Tracy doing some calorie-burning pelvic thrusts to a club track by Keri Hilson.
