It goes without saying that when Aamir Khan puts his mind on something, everything else takes a backseat. Now that he’s signed on to play the bad guy in the third instalment of Dhoom franchise, Aamir has already begun working on the physical aspect of his role.

For instance, while holidaying with wife Kiran Rao in Bali, Aamir made sure to work out regularly. Now, he continues the regimen in Mumbai.

A source says: “Aamir is known to change his look from film to film and ‘Dhoom 3’ will have him in a new look altogether. He’s already started working on it.”

Buzz is that Aamir might build the eight pack abs, just like he did for his role in Ghajini. That preparation took about a year. For Dhoom 3 too Aamir has time on his hands to develop the physique he wants for his character.
