It is been known that Salman Khan won't do all the dangerous wrestling scenes himself in his next film 'Sultan', and would take his physique to three different phases in quick succession. A source said, “Salman has already gone through the bulky phase. He will get rid of all the extra flesh for the lean look in the next one month, which is phase 2 in his character Sultan's life. Then Salman will go to Phase 3 for the muscular look. Post his neurological condition, these swift changes in his metabolism are not advised. But this time Salman is determined to make his character as authentic as possible.”
