The actor can currently be seen in action thriller Rowdy Rathore opposite Sonakshi Sinha.
He told The Times of India: "Action Dad, Action Hero, Action Man - these are the only titles I've ever wanted in my life. I would be unbearable, and bored, if I wasn't given the opportunity to push my body to its limits on a regular basis. I haven't felt this alive since shooting Rowdy Rathore.
"There's something very personal and thrilling about doing my own stunts. I'm addicted to the fear and adrenaline. I don't want anyone to try these film stunts at home, but I do know that one hasn't lived until one has greeted their fears with a twinkle in their eyes!"
Kumar revealed recently he wants to take on more villainous roles on screen.
He was recently gifted a Harley Davidson by his Desi Boyz co-star John Abraham.
