The 49-year-old actor also showed concern over Aamir's health, who while working on his stint as a wrestler in "Dangal", suffered a shoulder injury and has been advised bed rest for a week.
When asked what precautions will he take for 'Sultan' considering his actor friend Aamir got injured, Salman says, "Not serious na?" (related to Aamir's injury). "I will not use duplicate ...I will make sure I do it (action). I will train hard for it. I will have to get bigger and strong and that is difficult. I am 88 (weight), I will have to reach 94 and then come down to 70 again. It will be all muscles," the "Bajrangi Bhaijaan" star said.
The film directed by Ali Abbas Zafar will release next Eid.
Meanwhile, Salman expressed grief over the demise of veteran actor Saeed Jaffery with whom he worked in couple of films.
"He was a fantastic person and I have known him and his family for a long time. I think he died peacefully in his sleep... may his soul rest in peace," said Salman.
