"My only brief to my team was that we are not preparing an actor, we are training an athlete to win gold at the next Olympics. There was a lot of hard work, training everyday, six hours out on the field and then the gym. We had three athletic instructors, a technical expert for speed and endurance, all that is required to train an athlete," Mehra said.
