Shahrukh Khan To Do Dhoom 4 !

Bollywood superstar Shah Rukh Khan says that though he has been grappling with injury problems, he is fit enough to do an action film.

"When I was doing 'Chenani Express' I was injured, but I did it. It hurts a little, troubles you a bit, you need to be careful. If I am offered an action film, I will do it. There is no big deal about it. I am fit enough to do an action film again," Shah Rukh said here yesterday.

"I never wanted to be muscular. Everybody has a body type. I have nice, lean long muscles. I am happy with them. I don't like to show off. By March I need to be thin, I want to do it. I am working out everyday. I want to be fit," he said.

The Bollywood superstar was speaking at the launch of Deanne Panday's fitness book 'Shut Up and Train'. "The book has strong message -- don't look for excuses to not work out, start training. Like I finish shooting at 10 or 11 pm, I come home, put the kids to sleep, have dinner, spend time with family. And then at 2.30-3 AM I work out. My trainer pushes me to keep training whenever I get time, but (do it) everyday," he added.

Due to the number of injuries SRK has suffered, he does find difficulty while doing some sort of exercises.

"I can't do over head and shoulder exercise at all. Because of my spinal injury, I can't do a lot of things. I used to love doing pull ups, but I now can hardly do three-four. I can't do exercise with bars. As soon as I stretch my arms, I can't balance things. I can't lift too much weight," he said.
