Losing and gaining weight for a role is one thing, Bulking up to flaunt vein-popping muscles is another.
With his recent physical exploits, Farhan Akhtar joins the list of current Bollywood actors who have spent endless hours pumping iron to chisel out a fabulous body.
And all this, to slip into the shoes of his upcoming character of an athlete. Here's looking at Farhan from more than a decade ago and the actor he is now.
On the extremes
Michael Fassbender had to follow a medically monitored crash diet and restricted himself to 600 calories a day in order to portray Bobby Sands in the appropriately titled Hunger (2008).
Tom Hardy followed the bulking up act of Warrior (2011) with The Dark Knight Rises (2012). For the role of the masked evil Bane, he gained 14 kg thus increasing his weight to 90 kg.
