Arjun Rampal, who has one of the best physiques in Bollywood, has been giving up on his hours of sleep and following a strict regime. The actor has been spotted jogging during wee hours and building up his stamina, for what stays a mystery.

Known to be a fitness enthusiast, Arjun has been seen sweating it out, working out and jogging, as early as 4 am. The actor was an athlete during his college days and even ran for Tamil Nadu at the state level, back then.

With the Marathon being around the corner, the question is if the actor has been preparing to participate in the Mumbai Marathon, this year or is it a new demanding role in his kitty. Only time will tell.
