The item number Sheila Ki Jawani from the Farah Khan directed movie Tees Maar Khan had become widely popular.
In Dhoom 3, the 32-year-old actress was the leading lady of the film and was seen as an acrobat.
"I had to do intense physical preparations for Dhoom 3 and also for Sheila Ki Jawani and with Pilates I got it right. Pilates is a gentle way of training. There are no shortcuts to become fit. One has to stay fit and healthy," Katrina told reporters. (Also Read: Saif Says Phantom Co-Star Katrina Kaif Very Passionate About Work)
"Depending on the demand of the role we have to either have a toned down look or an athletic one. We have to keep altering accordingly," the Ek Tha Tiger star revealed.
