It’s never easy for an artist to work on biographical projects, especially the ones created on sports legends. Farhan Akhtar isn't one to easily back down when given a challenge. Farah Akhtar in ‘Bhaag Milkha Bhaag’ portrayed an Olympic athlete, Milkha Singh. Playing the part of an athlete may sure be difficult but transforming into one is definitely more crucial. He performed a rigorous workout regimen alongside a strict diet for his ripped muscular physique. His physical transformation in ‘Bhaag Milkha Bhaag’ was repeated by him once again after a few years in ‘Toofaan’. This time he was playing a boxer, and he had to prepare himself once again to get that look and that physicality right. To add to that, in the film he also had to play a father having a regular dad bod. So, from being in that physique of a boxer to becoming fat to play the father and then again losing the fat before starting another project, Farhan Akhtar did it all in the blink of an eye.
