Salman Khan has been working hard to get a bigger and better physique for his upcoming movie "Sultan", and a recent photo suggests as much. A picture has gone viral on Twitter in which Salman is seen working out in the gym.

The superstar wears a black hoodie and is seen holding weights, with aggression on his face. Salman will play the role of a wrestler from Haryana in "Sultan", and the actor had earlier said he would be seen double-sized in the film.

Salman is ready to celebrate his 50th birthday on 27 December, but is actually making age just a number.

After the first-look poster of Salman in "Sultan" was released, another picture did the rounds of social media in which he was seen posing like a fighter. And now, this new photo of his working out is breaking the Internet, so to say.

A leading lady for the film, directed by Ali Abbas Zafar, is yet to be finalised. Although there has been much speculation regarding the lead actress of "Sultan", makers of the film have clarified that no one has been finalised yet.

The film is expected to release on Eid next year.
