I get my drive and determination from just winning and playing tennis. I know if I don't work, I won't get rewarded. It was a life long dream to win a Grand Slam so when I was able to do that it felt so good and I wanted to do it again. It's not that hard to stay motivated.

My workouts include aerobic exercise for a healthy cardiovascular system; strength training to maintain muscle tone and bone density; core strength exercise for a stable mid-section; and stretching to maintain mobility.

Daniel, my big brother, is eight years older. I'm lucky he didn't mind hanging out with his little sister and my younger brother.

I love to get home and hang out with my family. My brothers and I love spending time at the beach. I enjoy doing all kinds of surf sports and keeping healthy.

I started mountain-bike riding two years ago, which is much better than riding a stationary bike in the gym. Mountain biking is a total body workout.

You're the best in the world, so you deserve those little perks along the way if you can get them.

Tennis Australia really led the charge as far as upping the prize money and trying to do the right thing by the players. They also led the way so women have equal prize money in all the grand slams too.
