“It’s important for women to have overall strength, because when you feel physically powerful, it transcends into every facet of your life,” says Jillian Michaels, who sheds her clothes and shows off the rockin’ bod she’s famous for on the July/August 2014 issue of Shape magazine.

In the mag, The Biggest Loser trainer, who has two daughters with partner Heidi Rhoades, shares her secrets for her tip-top shape — and how women need to feel strong overall.

“There are so many good reasons to exercise,” she says. “It doesn’t matter how profound or superficial your motives are, as long as it’s something that matters to you.”

And just like that, the super-fit trainer joins Pink, Britney Spears and six more stars to prove strong is the new skinny!
