Supermodel Heidi Klum has always had a super slim body and showed it off at the amfAR Inspiration Gala last week. The Project Runway host is a mom to four children and has a very busy work schedule that includes her collection of workout gear and shoes in partnership with New Balance.

Between work and being a hands-on mom, this model has her hands full, but she always finds the time for exercise. Actually, her beauty routine is simple, and she puts most of her emphasis time-wise into workouts—but then, even that doesn’t come close to food.

Klum likes to keep her diet as simple and clean as possible. She enjoys fresh fruits, vegetables, and lean proteins as main parts of her diet. A few years ago, she decided to start drinking a fruit and veggie smoothie every morning, and she has kept it up.

When it comes to the working out, even Klum admits to having days where she just isn’t feeling it. But good music and cute workout clothes help get her motivated. When she does exercise, which is pretty much every day, she likes to do circuit-training workouts, strength training, lunges, step-ups and rows, and belly-targeting exercises to keep her abs firm.
