Given, the locality and the narrow lanes of the city where they have been shooting these sequences, Akshay has been asked to train in free running called Parkour. Since Parkour is known for jumping and running in congested places with very little open road / ground to run, it was the perfect style to depict the chase sequence and the agility that his character requires.
He has been training in this style of running since few weeks and will soon be shooting his on-road chase sequence.
Akshay Oberoi says,"Yes, I have been training in Parkour. I think running is the best form of workout and Parkour takes it to another level and helps make your body and mind agile"
