Katrina Kaif has extended her workout time to five hours a day for her upcoming film 'Dhoom 3'

Katrina Kaif's upcoming film Dhoom 3 is an action-packed project. And while the actresses in the last two installments of the franchisee have stayed away from high-octane drama, the third rendition seems to be different.

Sources say Kat is expected to be seen in an all action avatar and has stepped up her workout regime to fit the bill.


A source says, `Katrina is going all out to prepare for her role. Since the last few days Katrina's trainer who has come down from London has upped her training schedule from two hours to five hours. She is being trained for her stamina, resistance and strength. She needs to be in peak shape to perform her scenes.`


While for a layman, five hours may seem too much but apparently Kat is taking things in her stride. `Kat's trainer has divided her workout into two schedules. During her break, she finishes her meetings and sometimes even squeezes in film dubbings, ` adds the source.
