"My name is Annie Mist Thorisdottir, I come from Iceland. I am the fittest woman on earth."

The two-time Games champion says you can expect to see her in competition for a long time."You always find new limits in a competition, and I haven't yet found the one where I completely break down."

Since 2009, Thorisdottir is completely "in CrossFit." She goes to CrossFit Reyjkavik, met her boyfriend through CrossFit, her parents do CrossFit and her brother competes on a team. "CrossFit gave me that something extra that I kind of needed in life."

The 2012 Reebok CrossFit Games will re-air on ESPN2 starting Dec. 16.
