"I'm now 43, my stomach has stretched in and out and in and out and in and out four times," Klum, who is the mother of four children -- daughters Helene, 12, and Lou, 7, and sons Henry, 11, and Johan, 9 -- dishes. "I've breastfed four children. You just have to embrace it, go with it, just roll with it."
"I love my shape because it's mine," she adds. "At the end of the day, it's not what anyone else thinks about my body but how I feel about myself. I'm working it and owning it!"
In addition to taking care of her kids, whom she shares with ex-husband Seal, Klum keeps herself busy with a myriad of projects. She's a judge on America's Got Talent and the executive producer and host of Project Runway. She's also the creative brains beyond Heidi Klum Intimates, a fashion collection featuring swimwear and lingerie.

With such a busy schedule, how does she stay fit? By doing things that "don't feel like work."
"I try to be active as much as possible," she says. "I don't have time for workouts every day. Being the mother of four kids is a workout in itself! Balancing my work and their schedules makes it hard to find time for a traditional exercise routine, so we try to do as many outdoor activities as a family as possible. We love to go on bike rides, take our dogs hiking, or jump on the trampoline."
Klum admits that staying motivated isn't always easy, but whenever she needs an extra push, she just thinks about "the big picture."
"I remind myself that I'm staying active and eating right to live a better and healthier life," she explains. "I want to be as healthy as possible for myself and my family."
