Varun Dhawan has been rigorously working on a lean and mean look for a bare-bodied fight sequence in brother Rohit Dhawan's action drama, 'Dishoom', which also features John Abraham and Jacqueline Fernandez.

The unit will be filming a 35-day-long schedule for the Sajid Nadiadwala film in Abu Dhabi and Varun is expected to look completely different. "He's a hardworking boy and began working on his physique immediately after wrapping up Dilwale. We've been training for an hour-and-a-half everyday to achieve his wishful target," revealed Varun's trainer Prashant Sawant who has been sweating it out with the actor for the past four years.

Varun's current routine involves more cardio and stretching, which will make him more muscular yet keep him flexible. He is following a high protein-low carbs diet of chicken, fish and salads. “He's always been in great shape. Often, he visits the gym twice a day, sometimes, even after his dance rehearsals. He even exercises between award shows and while travelling. I know he will achieve the desired physique by next week, just before he flies off," said Prashant.

'Dishoom' is produced by Sajid Nadiadwala under Nadiadwala Grandson Entertainment.
