Aamir gears up for yet another makeover, this time for his role as gymnast and martial arts expert in Dhoom 3

If Aamir Khan could build the most chiseled body in B-town for Ghajini and then break it down to look like a lanky teenager in Three Idiots, it shouldn't be surprising if he transforms himself yet again for his next action- thriller Dhoom 3. But, this time, the makeover may have to move beyond just the flab!

Apparently the actor, who is playing a gymnast and martial arts expert in the movie, will have to undergo a complete change of physique, not just in terms of weight but also body language.

For this, he has hired fitness expert Gerald Zarcilla to train him in martial arts and gymnastics. Aamir said during a recent interaction, "I have to bring down my weight to 60 kgs with just 10 percent body mass. So that's going to be a task."

The actor, who weighed around 73 kgs in Ghajini, had to lose around 5-6 kgs to look younger in Three Idiots. But Dhoom 3 will certainly be the thinnest you'll the star since his early days.

Adds a source, "For playing a gymnast, your body has to be a lot more flexible and being lighter obviously helps. Aamir will undergo a lot of functional training and free hand exercises for the same."

His former trainer Satyajit Chaurasia, who helped him pack-a-punch with his eight packs, adds, "Before Three Idiots, he had said to me that his body feels like the Taj Mahal, and now I would have to break it down.

But, by now, Aamir's body is flexible enough to mould into any shape or size. Of course, his dedication to get it absolutely bang on is commendable."

Diet another day

Though he is required to lose weight, eating less is the last thing Aamir plans to follow. Adds the source, "In fact, Aamir is eating more and eating healthy. He eats 12 meals a day and drinks at least 4 litres of water.

He has never had a sweet tooth as such, so he is pretty good at resisting unhealthy food."

Apart from 2-hours of martial arts training and regular gym exercises, Aamir apparently swims for an hour everyday.
