Andy Murray has claimed that he is eager to push his body to the limit when he begins his bid to win the World Tennis Tournament in Rotterdam.
The Wimbledon champion was forced to undergo surgery on his back towards the end of the last season and claims that he is still finding out how successful his recovery has been.
"It is important for me to challenge my body just now, to see how good it is. I obviously played my first five set matches in Australia, then in the Davis Cup," Murray told reporters.
"In those events you have a day off between matches, but if I play well this week I will be competing a few days in a row. The next month or two, I will still be learning about my body. But so far it has been good."
Murray takes on Edouard Roger-Vasselin on Wednesday.
