That's the Wimbedon programme for this year they are examining, on the page they are reading is an article about Andy's fitness/training regime at the end of the year in Miami and how intense it is compared to the rest of the Top 4's. The picture of Nole accompanies the article. It's a good article actually but very long, about four pages.
How does it compare, out of interest? I imagine Novak's will be just as tough (and Ferrer's for that matter), not sure about the others.
