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.

You've just got to get over that mental hurdle and those battles in your own head during matches when things aren't going so well. It takes time. It's probably all things I already knew, but for someone to talk about it maybe in a different way makes you realise things.

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.

In tennis it's easy to get greedy - and one Grand Slam doesn't feel enough any more.

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.

I love anything that involves the ocean. Swimming, snorkelling or surfing are all fun, which distracts from your mind that you are actually doing a workout. Being outdoors in the sun and the salt water is great for freeing your mind and feeling alive.

Tennis takes care of everything. It requires agility and quickness to get to the ball, core strength to get power into your shorts and stamina to last for an entire match. In addition to toning your arms and shoulders, it's a total body workout for your legs and abs, and works your heart and core unlike any other sport.
