3. Brenda Song | Taekwondo
Song played Christy Lee in The Social Network and was a regular on a Disney show called The Suite Life of Zack & Cody that, depending on your age, we hope you never watched. But it was her Disney movie that we hop you never watched, Wendy Wu: Homecoming Warrior, which allowed her to showcase her black-belt skills in taekwondo.
4. Eve Torres | Jiu-Jitsu
Torres is a WWE Diva, but what makes her an ass-kicker is her blue belt from the Gracie Jiu-Jitsu Academy. Watch her train in this video, and try not to get jealous when she wraps her legs around the dude to choke him out.
