Katrina Kaif Aamir Khan in Dhoom 3

In the thirty second long promo of the song, which seems more like an advertisement for an aerobics DVD, we see Katrina Kaif somersault, rotate on aerial ribbons and twist herself in every conceivable way. What does Aamir Khan do meanwhile? Sit and watch smugly. Also, in just a matter of thirty second we see Kaif strip down from overcoat, jeans and hat to shorts and tank top. The song seems upbeat and catchy and the promo has been brilliantly edited. Reportedly, Katrina went through a rigorous training regime for her Dhoom:3 role. The actress has been trained by fitness experts Reza and Yasmin Karachiwala.
