Priyanka Chopra can pack a punch

To get into the skin of the character of boxer Mary Kom, Priyanka said she had to work on different things. "Being an actor I am supposed to train, but I am very lazy. It is horrible. I look fit and athletic and that is because my parents genetically look fit and they did not put weight till they were 45 years old. I am blessed that way. I had to go to gym for this film which was my punishment. I did hate going to the gym and I wanted to kill my trainer," she said in a lighter vein.
