After doing a few human dramas in the past two years, Salman Khan is returning to his home turf — action — with Tiger Zinda Hai. Well aware that the spy thriller, replete with its high-octane action sequences, would be physically demanding on him, the actor had to undergo intensive prep. Director Ali Abbas Zafar reveals that Khan hit the gym three months before the film went on floors, to attain the muscular look. "Salman has really pushed himself for the part. He started working out three months before we began the shoot in Austria, to ensure that he had the fitness level that a film like this demands of you," he says.
