Physical fitness and activity are crucial to ensuring Soldiers are able to perform the duties and responsibilities of their jobs. Practicing principles of safe and effective training enables Soldiers to maintain physical readiness and health. Soldiers and leaders across the Army agree that activity and fitness are essential to being a strong warfighter. Although Soldiers are generally more physically active than civilians, they are frequently at risk for overtraining and resulting injuries. Profiles and Army Physical Fitness Test failures are both associated with medical non-deployability. Despite obtaining some activity through structured unit physical readiness training, many Soldiers are sedentary over the course of the day, which can lead to adverse health outcomes over time.
