Superstar Shah Rukh Khan says that when it comes to working on body fitness, he can never be as disciplined as Aamir khan. Talking about Aamir, who first gained weight and then lost it for his upcoming film ‘Dangal’ ‘Shah Rukh’ shared that the PK actor works really hard on his body. “Aamir is very disciplined and works really hard on his body. Two years ago, when I had met him, he had put on a lot of weight and now he has lost all those extra kilos. I can never be disciplined.””Infact, I started working out only after ‘Om Shanti Om’, Shah Rukh said in an interaction for live video streaming and broadcasting destination #fame.” While Shah Rukh had built six-pack abs for ‘Om Shanti Om’, Aamir had gone ahead and worked on eight pack-abs for ‘Ghajini’.
