Actor Imran Khan is making sure he does not miss out on his fitness regime because of his busy work schedule. He called up his trainer on the sets of "Once Upon A Time in Mumbaai 2".

Co-produced by Ekta Kapoor and Shobha Kapoor, "Once Upon A Time In Mumbaai 2" is a sequel to the 2010 movie "Once Upon A Time In Mumbaai" and also stars Akshay Kumar, Sonakshi Sinha and Sonali Bendre in lead roles.

"We have been shooting 12-hour shifts every day, all month, without a single off. As a result, I have had to bring my trainer on the set to work out in between shots. We have also built a space for dance rehearsals, " Imran said in a statement.

Imran is also shooting for "Gori Tere Pyaar Mein".
