Tennis is all about mental toughness, and you have to keep your head in the game. I make time to relax away from competition pressures, travel and intense training schedules to make sure I'm looking after myself. Taking time out with family and friends helps to maintain the work-life balance everyone needs.

When I'm playing my best, like I was at the U.S. Open, I feel on top of the match and able to do exactly what I want. There are other times when you're not in control, but that is tennis and you have momentum changes in every single match.

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.

Core strength and stability is very important to me. Tennis is all about rotation of the body and my ability to create power. I incorporate a lot of abdominal, back and glute exercises into my gym sessions.

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.

Receiving the Newcombe Medal for a third year in a row is an amazing honour. The Newcombe Medal is a great occasion for the Australian tennis community to come together and celebrate our sport, recognise people's achievements and contributions to Australian tennis.
