A new era of full spectrum operations places service members under increasing pressures that lead to breakdowns in the human system, undermining mission success and force readiness. The U.S. Department of Defense is shifting to promoting a comprehensive model that optimizes physical and cognitive capacities to meet operational demands. The concept of “total fitness” provides the necessary framework to achieve a resilient military force ready and able to meet the demands of the 21^st century. “Total fitness” is a concept that integrates and optimizes the physical, psychological, social and spiritual components of the human operating system to prepare warriors to thrive in any operational situation. The successful emergence of this concept is generally defined by the following four goals: facilitate a cultural shift towards a proactive model of well-being; increase ongoing multi-agency and multi-disciplinary collaboration; identify and disseminate best practices, innovative programs and practical tools; and, increase the provision of needs assessments and consultation services for strengthening resilience-based programs throughout the globe.
