Losing weight post Sultan painful: Salman Khan

In the film, Salman's character Sultan was seen ageing from a young Haryana wrestler to an older man, for which he had to gain several kilos.

"There is a lot of pain in undergoing physical transformation. I have been training for Tiger Zinda Hai and there is another film that I am training - it's a dance film (referring to Remo D'Souza film)."

"For Sultan, I was 96 kgs. I have shed 18-20 kgs," Salman said. On work front, Salman Khan is all set to start shooting for Ali Abbas Zafar's Tiger Zinda Hai. The film is a sequel to Ek Tha Tiger which went to become a hit in 2012.
