He is a mixed martial arts fighter,” said the “Student of the Year” star.”There is more heavy weight lifting. I train less and eat more. Calorie intake is higher. There is more of protein in my diet. I train on alternate days or four times a week. But I also need to keep flexibility in mind,” he added.He is excited about the Endemol production as he wanted to essay the role of a fighter since childhood.”I wanted to play a fighter. Like every boy while growing up wants to do action and be in the ring…though I am not playing a wrestler,” said the actor, who won’t be seen with a female lead in the film.advertisement”I don’t have a female lead in the movie. It’s more about a young fighter.
