Amanda Knox is taking self-defense classes at a gym in Seattle, Washington, the Daily Mail reports.
According to the Daily Mail, the 24-year-old Knox is taking Krav Maga classes with her sister Deanna, 22.
Developed by the Israeli Defense Forces, Krav Maga is a combination of boxing, wrestling, and martial arts that focuses on disarming and disabling an attacker.
An unnamed source told The Sun, "She feels safer knowing she can fight back if she has to."
Since returning home to Seattle after her dramatic trial in Italy, Knox has been settling back into normal life. She recently started dating old friend James Terrano, a 24-year-old classical guitar student at the University of Washington, and the two are reportedly sharing an apartment.
She is also reportedly considering returning to college.
