Demand of Katrina Kaif can be gauged from Bollywood offers that have been pouring from all corners for the lady. Yet the girl feels nervous as Kat readies to work with industries most-sought after actor, the perfectionist – Aamir Khan.

Everyone knows that Kat will be seen with Aamir Khan in Aditya Chopra’s cool action flick ‘Dhoom 3’, and given Kat’s imprudence for the genre, the glam doll is experiencing goose bumps ever since the project has rolled out. Kat has started intensive and specialised fitness training to match the form of her co-star Aamir.

It’s been learnt that for the next 10 days, the actress will be undergoing rigorous training for four hours, every day at the Yash Raj Studios where a floor has been specially rigged up for the practice sessions. "The sessions are basically to determine what my stamina is like and how much I can take. Which is what is scaring me," Kat said.

Buzz has it that Aamir will be playing a ballet dancer in the film. Is Kat`s role similar? While she doesn`t want to divulge any detail, she is all praises for her co-star. "Just look at him. He`s maintained himself so well. It`s amazing. Even Hrithik, he`s always so fit. Women can`t work out so strenuously like that, you know. Our shoulders are not so strong. You ask a woman to do pull-ups and you`ll know," she said.
