A recent video of Amir Khan has become viral. The video shows the actor going through an extreme body transformation for his film “Dangal”. The actor gained 30 kilos over 6 months to play the role of aged and out-of-shape wrestler. But that is not all.. he then worked hard and came back to shape to play the role of a young wrestler. Girls, as the video shows, it is a game of willpower and all you need is to take one-step-at-a-time towards your goal.
