Want to break into tactical strength and conditioning? Start by understanding the physical and stress demands of tactical work. Whitney Tramel explains what coaches need to know before stepping into this space. Drawing on her experience across military, police, and fire settings, she outlines the training qualities tactical professionals need to stay ready. She also discusses the growing focus on “holistic health.” In her view, that means looking at the whole individual and supporting longevity across a demanding career. As Tactical Program Manager at the National Strength and Conditioning Association (NSCA) and a PhD candidate studying stress physiology, Tramel connects research with the realities of tactical coaching. She also addresses a side many coaches are not ready for: tactical athletes often trust their strength coach with conversations that reach far beyond training. Learn what the role requires, what coaches often miss, and how to enter the tactical field with clarity.
