Two things Hrithik Roshan is known for – his bulging biceps and his dedication towards fatherhood. The actor who is awaiting his release called “Mohenjo Daro”next month, seems to be quite regular with his fitness routine. Now onto fatherhood, he has begun to pass his workout skills to his two sons – Hrehaan and Hridhaan. The actor mentioned in his twitter account and posted a picture of himself and his sons working out together. Nothing like a father who includes his children in his own life.
