Rajiv Rai's spy thriller 'Asambhav' is coming soon, where Arjun Rampal would seem with his soft but tough guy act. "When I got to know that I had to play a commando in Asambhav, I had to get my six-pack back for the role. In the interim I had become a laddoo and I thought getting back in shape would truly be asambhav. But I am glad I did it," he says. He is training hard at the gym and also learning karate in order to make his body more supple. Arjun adds, "I used to eat only boiled food. But I am glad my body responded well."
