It's no wonder Shayk looks so good, though. The supermodel recently revealed how she works out for her enviable body. Shayk told Yahoo on Thursday that she works out a lot. Shayk said she usually works out for about an hour, unless she has more energy and then she'll also go for a run after.

"You cannot wake up and see yourself in the mirror and think 'I look great so I can just relax', you have to always push yourself to be better." Shayk also said that she does "a little bit of boxing, I do the Pilates machine, I work out with my personal trainer."

"Cardio's always good," Ronaldo's girlfriend revealed. "It makes you sweat, it's the best. If you love to run, it's the best, just to sweat it out."

She also revealed she loves eating burgers and fast food, though. "I have good genes but of course you have to push yourself to go to the gym," the Sports Illustrated swimsuit model said. "I'm 28. When I'm going to be 35, I still want to look good. My other problem is I love to eat, I love my food. I love hamburgers, I love chicken nuggets."
