At a recent press conference of the 10-year-celebration of film 'Rang De Basanti',Aamir said "I have put on weight and have to reduce it as well. I am a national level wrestler like Sushil Kumar ji. I had to put on 25 kgs, so have to now reduce 25 kgs and not just that make it look like Sushil Kumar..muscular, low-fat." He also added to say, "The phase of being overweight and elderly is about to get over. The process has started and my weight has started reducing now..I have started losing weight. My big challenge is to come back into shape like how my body was in 'Ghajini' or 'Dhoom 3'."

Sources say that, he has started his exercise to lose weight and to shoot some last portions of the movei 'Dangal'. In the movie 'Dangal', Aamir will be playing the role of a Haryana-based wrestler named Mahavir Singh Phogat, who taught wrestling to his two daughters, Babita Kumari and Geeta Phogat.
