Tyrieshia Douglas, 23, is training for the U.S. Olympic Boxing Team. Currently ranked number 2 in the country at 112 lbs, she will go up against the best in the country at the Olympic Trials in Spokane, WA, starting on February 12. Tyrieshia and her siblings spent their childhood in and out of foster homes, and dealing with a drug addicted mother. She says she's fighting not for herself, but for the world. "I want to open some minds for kids who've been through what I've been through. I've let go of everything for boxing. I'm doing it for the world, I've got nothing to lose." —Andre Chung
