Cindy Crawford always looks stunning, whether she's toting around her kids, going out with her superstar friends or glamming it up on the red carpet with her husband. What's her secret? She recently spoke to Time Online about her healthy habits and how she manages to look so darn good all the time.

"There is no secret, not like finding the perfect jeans," she says. "It's genetics - I was born with a good envelope - and lifestyle ... when I was 20, I was not super-skinny, so I got into exercise and it has become part of my life. You do not find time to exercise, you make time, otherwise you will find millions of other things to do."

And boy does she exercise. Crawford admits that before her kids, her workouts were so exhausting she had to rest afterwards, adding, "I found after I had my first kid I could not come home after my workouts and have a nap, so I had to adapt them to make them softer - so they would energize me, rather than wear me out."
