Mumbai, March 5 -- To maintain those fabulous abs and bulging biceps, Bollywood superstar Salman Khan, who set the trend of being fit in the showbiz, has to work three times more due to growing age and changing trends."When we are young people, used to forgive all your things and used to say he is a kid. That time we didn't even have to work hard. But now the more you grow, you have to work harder. You have to look younger; you have to be fitter, run faster, kick higher. All these things gives you trouble later," said the Dabang actor at the Cosmopolitan Friends Association event organized for supporting physically challenged, abandoned and orphan children.Saying that the more you age, the more hard you need to work out, the 46-year-old fitness freak stated, "I have worked hard for this body. And today I am finding it difficult because however much I have worked in those days that much these new kids are working out in today's date. So I have to work two-three times more".
