Ha Ji Won recently transformed into a sexy warrior for her upcoming movie, "Sector 7". Up until now, Ha Ji Won has taken on a variety of roles in her movie filming career, including a boxer, a stunt woman, and an officer. For "Sector 7", she will play the role of an oil rig equipment manager who is forced to fight an ocean sea monster. It has been revealed that Ha Ji Won underwent strenuous exercises to prepare for her action-packed role. She spent eight hours a day swimming and lifting weights and even went as far as obtaining licenses in both scuba diving and motorcycling. Moreover, in order to realistically portray her role as an oil rig manager, she pumped up her muscle mass to which her personal trainer said, "She has the most muscle mass out of all the actresses in Korea".

Ha Ji Won stated, "I have a petite physique, so I concentrated on weight training to prevent my action scenes from looking weak and powerless." A "Sector 7" representative further added, "There were scenes that involved explosions and dangerous stunts, but Ha Ji Won didn't use a stunt double and did all of the scenes herself in order to create a perfect woman warrior." "Sector 7" will be released on August 4th in 3D. Source: Seoul NTN via Nate
