 Maintaining combat fitness with limited time, resources, and space is always a challenge for the military. So a former Navy SEAL developed a cardiovascular suspension workout system that looks simple, but it's very difficult. It caught on wildly and has evolved into a competition. This is the TRX Mission Readiness Challenge, basically the military championship of TRX. It's four exercises for a minute each, with 30 seconds rest in between. My mind's going through my mind trying to get those reps, the control, just breathing in and trying not to critique too early. Keeping a consistent pace is critical, and this system plays no favorites to gender. Lance Corporal Lee Kay finished third, while the competition's lone female, Sergeant First Class Veridiana Levaye, took first. From Camp Pendleton, California, I'm Sergeant Todd Hunter.
