At a 'Shamshera' event, actor Ranbir Kapoor said he used to work out in actor Sanjay Dutt's gym during 'Barfi' and 'Rockstar'. "He used to tell me, 'You are working out for the past two years, but your body doesn't show it'," Ranbir added. Ranbir further said that Dutt has always had his back and has always inspired him.
