Red Bull driver Mark Webber says he is ahead of schedule in his recovery from a broken leg and will be fully prepared for next month's Formula One season opener.

Webber broke his right leg in November when he was hit by a car while riding a bicycle in a charity trekking race back home in Australia.

Webber has been undergoing treatment in a cryogenic chamber to aid knitting of the fracture, and was pleased with the results.

"I've been doing it for three weeks now," Webber told the Red Bull website. "You go from a normal, ambient room temperature into a chamber of -50 C for about 30 seconds and then for another three minutes into -130 C.

"It's very good for your general well-being, your immune system and apparently it's good for cellulite. Not much of a worry for me ... but it's very good for the whole body.

"The results over the last few weeks have been incredible. We had a really good week last week, so we're really positive. Dare I say it, we're probably a little bit ahead of schedule."

Webber expects to be back behind the wheel of a Red Bull late next week for the first time since the 2008 season closer in Brazil.

The Australian Grand Prix in Melbourne begins the new season on 29 March.
