His test in a 2009 Ferrari F60 blocked, Michael Schumacher instead turned to an Italian karting circuit to continue his preparation for his formula one comeback.

Accompanied by Ferrari test driver Luca Badoer, the 40-year-old German travelled to the Lonato circuit in Italy.

"Karting has a very good training effect, that is why today I just jumped into a testing day of the Tony Kart team in Lonato," he said on his official website michael-schumacher.de.

"There is nothing better for my preparations at the moment -- in terms of steering wheel forces for example karting is even more difficult than formula one," Schumacher explained.

The high ambient temperatures, meanwhile, pleased the local photographers, who were able to capture the results of Schumacher's weight-loss and training efforts as he walked the paddock topless.

"The fact that it has been boiling hot here is simulating the temperatures expected for Valencia," Schumacher added.
