Bollywood 'Perfectionist' Aamir Khan has always been known for his knack to prepare meticulously for each film. Be it his onscreen look or off screen research, Aamir does it all to make sure that the performance comes out as perfectly as possible. 

Aamir who has undergone a special fitness training for his role as the antagonist in 'Dhoom 3', recently went on a break for his Haj pilgrimage. While he recently resumed shooting of the film in Chicago, Aamir decided to make up for the loss on his training front. 

In order to get in top form of his fitness, Aamir planned a strenuous schedule, for which he hits the gym at 3am in the morning. 

Regardless of the shooting shift timing, Aamir has been religiously working out in the gym for two hours daily.

After working out he freshens up, has his breakfast and then resumes shooting for the day. 

Great dedication Aamir!
