Jillian Michaels covers the July/August 2014 issue of Shape magazine and appears nude within its pages. The Biggest Loser coach, who is 40, says she feels better about herself at this age than she did in her 20s and 30s.

“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,” she told the magazine.

Even though Michaels goes to the gym regularly to stay in shape she says staying strong is even more important.

“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.

Jillian Michaels claims there are still parts of her body that haven’t reached perfection–even though she looks pretty darn perfect to the naked (no pun intended) eye. She even tweets about her photos in Shape, saying she has made progress with the ‘ass man.’

“Do I want to have a better butt? Sure, but I’m healthy and can wear my skinny jeans,” Michaels said, “And that’s good enough!”

The trainer needs ample energy in order to chase after daughter Lukensia, who is 4, and son Phoenix, who is 2. She and partner Heidi Rhoades no doubt have their hands full with two little ones at home. Staying in good shape provides the energy needed to be very active parents.

Don’t fret if you haven’t yet found the issue of Shape in which Jillian Michaels poses nude. It hasn’t hit news stands yet–but it will soon. Look for the July/August issue to go on sale on June 25th. Will you be checking it out to see exactly how good The Biggest Loser coach looks sans her clothes?

How do you suppose Jillian’s fellow Biggest Loser coaches will react to the full view of her body?
