Andy Murray looks in fine fettle ahead of his assault on the 2013 Australian Open.
The Scot has added three pounds of muscle as he looks to build on his 2012 Grand Slam-winning year, when he won the US Open in September.
Murray, 25, spent the majority of December in Miami where he doubled his weekly weightlifting sessions from two to four as he continues to bolster his shot power.
He has been seeded third for the first Grand Slam of the year in Melbourne, behind Roger Federer and world number one Novak Djokovic.
Murray was victorious at the Brisbane International last week where he dedicated his victory to former doubles partner Ross Hutchins, recently diagnosed with Hodgkins Lymphoma.
