Known to be a method actor, Kangana Ranaut usually leaves no stone unturned to prepare for her characters in her films. The actress has just signed a Karan Johar film that will soon go on the floors and apparently she will now be learning crossfit training to get into the skin of her character. A source informs, "The film helmed by Rensil D'Silva is a thriller. This will be her first KJo production and she wants to give it her best shot."

Sources say that Kangana plays a medical student in the film. The actress had also done rigorous physical training for her superhero film, Krrish 2 with Hrithik Roshan. The source adds, "It was her decision to undergo the training process so that she looks her best in the film."
