Former world tennis No.1 Lleyton Hewitt claims he has trained harder than anyone else on the circuit over the past two months as he embarks on yet another comeback from injury.
Hewitt's 2010 campaign was brought to an early end in September when he seriously injured his right hand in Australia's Davis Cup loss to Belgium in Cairns.
The 29-year-old also underwent surgery on his hip and knee earlier in the year, capping a frustrating period in his career after also battling a serious hip complaint in 2009.
But after a rigorous two months on the training track, Hewitt says he is finally injury free and the fittest he has been for years ahead of the the Hopman Cup which starts today in Perth
