 The Joint Warrior Competition at Camp Lemonnier brings all branches of the US military together to test their medal against an exhausting lineup of mental and physical challenges. These warriors push themselves to the limit and hold nothing back, all for love of country, camaraderie, and of course bragging rights. Everyone has their own reasons to push themselves this hard. And for Catherine Dunn, the road to competition has been a journey of self-improvement. Four years ago I set out on a journey to lose 90 pounds and now I'm a competitive figure bodybuilder. I was told that I'll never compete and I was like, oh yeah, well, let me show you. As people often do, Catherine found herself at a place in life where she wanted to make some changes. In 2011 I deployed to Kuwait and I didn't like where I was in life. I just got to that point where I had that aha moment and I looked in the mirror and I said, you have to fix this. I kind of played around in the gym a little bit and I really got into lifting. This journey started later on in life. It started when I was 35 to lose the weight and to get fit. I always tell women, especially women, that you can do it because people think, oh, I'm past 30 or I have kids or I'm divorced or stressed and this and that. It's a lifestyle. Perhaps the secret to Catherine's success is that her fiercest competitor is herself. It's not so much the competitive drive that I want to beat other people. It's just every day I want to better myself and become better than I was yesterday. Reporting from East Africa, I'm Tech Sergeant Benjamin T. Hayes.
