VIDEO: Not even UFC middleweight Luke Rockhold can protect his arm from Ronda Rousey

More brute force than she's used to expending but Ronda Rousey gets the job done.

When rolling with UFC middleweight Luke Rockhold, who walks around at over 200lbs, Rowdy didn't have too much trouble locking in an armbar. Rousey (11-0) has nine submission wins via the technique that has earned her the nickname of "the arm collector" and it's kind of easy to see why. We can't really see which 135lb female is going to be able to hang with Rousey's level of grappling when male middleweight contenders can't keep their arms away from her. Video via BJPenn.com
