In the Nitesh Tiwari-helmed sports drama, Aamir portrays the role of a Haryana-based wrestler Mahavir Singh Phogat, who taught wrestling to his daughters, Babita Kumari and Geeta Phogat.

"I have put on weight for 'Dangal' 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," Aamir told reporters here at the press conference of 10-year celebration of film "Rang De Basanti".
