Ranbir Kapoor is back in the swing of things after being taken ill a few days ago.

The actor is said to be working aggressively towards preparation for the next schedule of his film ‘Brahmastra’.

A source told The Asian Age, “Ranbir is not fond of working out,” says a source. “But for this film, he has been asked to sport a lean body. So, he has been working out rigorously to get the look right. He’s also been put on a very strict diet for this project.”

Kapoor is set start promotions next month for his Sanjay Dutt biopic, tentatively titled ‘Sanju’.
