Mumbai, Dec 9 (IANS)

Shah Rukh Khan, who started disliking himself for being unfit and weak, says that his New Year resolution is to be fit.

"My fitness pledge is - in March, I need to be really, really fit. I want to have a body structure, which I have never had before. I really want to do it. I hope I don't get injured before that," the 48-year-old said here Sunday at the launch of Deanne Panday's fitness book "Shut Up and Train".

Shah Rukh's shoulder injury has been troubling him for quite some time and a few months back he underwent a surgery to cure the problem.

The 48-year-old is currently shooting for Farah Khan's "Happy New Year", but he is following a strict regime to ensure that he is fit and healthy.

"Even though I am shooting, I am working out almost everyday. I really want to be very fit," he said.

"Last year I found so many excuses to be unfit. About two months ago I started to hate myself that I am so weak and I am so prone to give into my weaknesses. So now, I want to work really hard for the next five-six months," he added.
