Kangana Ranaut is relying on martial arts training to ensure that she doesn’t gain even miniscule weight in order to fit into her skin-tight outfit for her next movie based on a superhero.

The actress is also carefully viewing her diet plan to make sure nothing goes wrong. It’s learnt that for her role as the mutant in the flick, Kangana has to also train in fighting techinques for her action sequences.“She is learning a few tips of karate, judo and taekwondo,” says our source.

Apparently, Kangana had to shed about 5 kilos for her part to fit into her outfit. Obviously, the actress also has to put up with her fair share of bruises after performing her own stunts during the shoot. Our source says, “Since she’s training in fighting technique for her character, it’s natural for her to perform her own action scenes. Kangana knows that several bruises can’t be avoided.”
