There's no doubt that Danish tennis star Caroline Wozniacki has one of the greatest bodies in the world — one that's not only helped her win championships, but has also expanded her horizons when it comes to photoshoots for glamour magazines.

Wozniacki revealed that her disciplined beach workouts besides a lot of running is the secret to her toned body. "I do a lot of beach workouts. I used to do a lot of running as well, but now I need to take care of my knees, so I go on a bike, then I run on the beach and do sprints. I do paddle-boarding for the balance. Being fit keeps me happy," Wozniacki, who is all set to marry ex-NBA ace David Lee this year, told ESPN recently.
