Jillian Michaels "Can't Handle" Ruining Body with Pregnancy

Biggest Loser trainer Jillian Michaels has sworn never to get pregnant — because it would ruin her body.

Jillian, 36, admits she would rather adopt a baby than give birth since she doesn't want to undergo the physical changes that occur during and after pregnancy.

"I'm going to adopt. I can't handle doing that to my body," she told Women's Health magazine via The Huffington Post. "Also, when you rescue something, it's like rescuing a part of yourself."

Jillian -- who is now 5'2" and 120 pounds -- was overweight as a teen. She said she once weighed 175 pounds but lost the extra weight with martial arts, which she has practiced for 20 years.
