Supermodel Heidi Klum has a sizzling swimsuit body at 42, thanks to a low-carb diet and regular workouts with celebrity trainer David Kirsch.
"I'm pretty good about not eating too many carbs," Klum told Us. "I love vegetables. I don't eat bagels—no way! A bagel is basically a cardboard box. Usually I'll have a smoothie in the morning."
Heidi avoids processed foods and makes sure her daily diet features fresh vegetables and home-cooked German meals. "I like to stick to fresh fruits and vegetables and lean proteins," she said.
The super-toned mom of four also tries to work out every day, if possible. The 5-foot-9 Klum said her favorite workout in New York is running along the Westside Highway, which stretches along the Hudson River.
The German supermodel also does circuit-training workouts, strength-trains, does lunges, step-ups and rows, as well as belly-targeting exercises to keep her midriff toned.
Klum makes an effort to incorporate exercise into her daily life by hiking with her children when they're in Los Angeles, running on the treadmill for 30 minutes at home, and doing sit-ups and other calisthenics in her hotel room whenever she travels.
When she has time, Heidi also works out with her longtime trainer, David Kirsch, author of The Ultimate New York Body Plan.
Kirsch combines cardio workouts with ab exercises and strength-training to keep the blonde beauty in bombshell shape. David, who also trains supermodel Kate Upton, is the creator of The Ultimate New York Body Plan workout DVD.
Hasn't Had Plastic Surgery and Doesn't Want to
While most people dread getting older, Heidi is comfortable with aging and has no interest in getting plastic surgery. "I don't think of getting older as looking better or worse; it's just different," she said. "You change, and that's OK. Life is about change.
"I don't have anxiety about [aging], so I'm not running to get Botox. Maybe that will change, but I don't think so. I feel comfortable in my skin and comfortable with aging, so I think it's OK that I get wrinkles."
Klum has maintained her fame and fortune for more than 20 years, thanks to her incredible self-discipline. "I'm a big believer in to-do lists," she said. "I have daily lists and big-picture lists. I set goals and get my work done, but I have to plan for fun things, too."
