Just two months after having son Henry, a lingerie-clad Klum was strutting down the runway in a Victoria's Secret fashion show. She had quite an incentive to get her bod back: Klum confessed she was under contract to lose her post-pregnancy weight in just one month! Reportedly, her $25 million deal with Victoria's Secret bans her from "altering her image."
How she did it: Klum turned to trainer David Kirsch, whose weight-loss regimen is anything but relaxed. Kirsch recommends 90 minutes of exercise every day(!) that includes strength training and cardio. Her diet? "Lean, clean, and green. No dairy, lots of greens, grains, egg whites, and protein shakes," he says.
