Hottest Celebrity Bodies, According To 'Biggest Loser' Trainer Jillian Michaels

Jillian Michaels plays a tough fitness coach on "The Biggest Loser," but the results on the NBC weight-loss reality show speak for themselves. In a new interview with Health magazine, where the 38-year-old graces the cover flaunting her incredibly toned abs, Michaels says that she makes the show contestants earn it. "If I'm taking time away from my company and kids, you had better show the f*ck up and mean business. I would say I'm worse than ever!" she said.

Alrighty then! In the meantime, Michaels did say who she thought had the hottest bodies in Hollywood, all female musicians: Jennifer Lopez ("she looks crazy [good]"), Rihanna ("thick and curvy and sexy"), Beyonce ("that's a sexy body") and Pink ("I gotta say Pink, because I helped her.")

And while these four ladies have personal trainers and intense schedules that help them keep in shape, it turns out that Michaels' top diet trick is actually free. Yes, free. "Stand whenever you can," she advised. "Standing burns 1.5 times more calories than sitting. Stand when you're back at the doctor's office, when you watch TV, even when you work at your computer -- I put mine on the kitchen counter. Just stand."
