Get to know Army Lieutenant Colonel Nick Barringer, Program Director for the United States Army-Baylor University Master’s in Nutrition. Barringer shares how he originally planned to become a strength and conditioning coach before a nutrition course inspired him to pursue dietetics. However, it was his Certified Strength and Conditioning Specialist® (CSCS®) credential that ultimately landed him his role as the first 75th Ranger Regiment (Army Rangers) Dietitian. He recounts drawing inspiration from the Navy SEALS to start the Ranger Athlete Warrior (RAW) program and seeing the Special Operations THOR3 program follow suit — laying the groundwork for the US Army Holistic Health and Fitness (H2F) system. Barringer and McMahon discuss the synergy between strength and conditioning coaches and dietitians, as well as cultural challenges and diverse training ages in tactical settings. The pair also stress the importance of sales and building relationships before discussing basic nutrition advice and pathways into tactical and dietetics careers.
