When you go to the theaters next summer to see Iron Man 2, don’t be surprised to see some skinny, former shell of the curvy girl we all used to love. Scarlett Johansson has been working out with Tracy Anderson, the hard-core trainer that is responsible for Gwyneth Paltrow and Madonna’s rock hard bodies.

Tracy’s program is sound, but it’s majorly time consuming and intense. Scarlett has already lost about 14 pounds working out with Tracy and you get tell by these before and after below how much smaller she looks. Actually..that is Tracy’s “thing”. Her program promises to make you “tiny” not skinny.

She said of the singer: ‘I want to keep her body looking like it’s 20 years old.

‘Because you don’t have to have saggy arms, or poor skin tone in your 50s, or not have cute hips. It just doesn’t have to happen.’
