A source told a website, "Since Aamir plays a gym instructor in Dhoom 3, it isn't just a great physique that he needs to work on. Aamir needed a particular kind of physique to look convincing as a physical trainer. He also needed to learn the art and technique of physical training in the gym. This is where Aamir without hesitation sought the help of Tiger."
Tiger Shroff who hesitated initially to train Aamir Khan said, "Yes, he was kind enough to invite me for a workout with him. But what could I possibly offer Aamir Sir?"
Tiger also revealed, "We did some functional and core-related workouts. They were basically exercises that engage and recruit your abdominal muscles."
It seems like Tiger shroff is all set to join the bandwagon of star sons!
