Vivek is been trained in martial arts and is learning parkour (type of martial art) from London based Alexandroun, while David was flown down from Thai to teach the actor ikido muay thai (Thai kickboxing) and Tae kwon do.
Vivek is being training for six hours a day. He says it's a very rigorous schedule which requires him to practice 1500 kicks a day. He starts his day at 6 in the morning. His main focus is on weight training.
Vivek says he needs to acquire fitness and shape for his character. Vivek adds that he wants to look good in every film. So in order to be fit he is undergoing training by Satyajit Chourasia also.
Vivek's parkour type of jumping came into picture by the famous and Hollywood's sexiest man, Daniel Craig in his movie Casino Royale. Daniel brought parkour jumping into picture and it proved to be quite famous. Parkour jumping is basically a kind of jumping where one jumps off buildings to buildings.
After the Hollywood hunk, its turn for our Bollywood hunk to show some jumping acts (jumping in a big sense). Hope Vivek does all the jumping well and doesn't trip or hurt himself.
