Biggest Loser trainer Jillian Michaels poses in the buff

SHE’S 40 years old, she’s fit and she has a fabulous body. Check out Biggest Loser trainer Jillian Michael’s sexy magazine shoot.

THE Biggest Loser US trainer Jillian Michaels has spent her life whipping people into shape, and now she’s taking it all off for the pages of Shape magazine, revealing her own fantastically fit form.

Posing nude can be daunting — even for someone who spends as much time toning her body as Michaels — but the 40-year-old reveals that she finally feels like she’s come into her own.

“When I think back on my 20s and 30s, I look better now than I ever have. Yes, I’m older but I’m also wiser and that’s a more intrinsic type of beauty,” Michaels told the magazine.

Amazing body.

Ripped.

Michaels, a mother of two children under the age of five, regularly works out, and tells the magazine that a fit body is about more than just looking a certain way.

“It’s important for women to have overall strength, because when you feel physically powerful, it transcends into every facet of your life,” she said. “My best reason for having strong arms is because I love to pick up my kids.”
