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.

No two days are the same for Will Gilmore as part of a team that oversees over 800 athletes across 200 sports at the Red Bull Athlete Performance Center. From surfers to skydivers, the facility provides an elite high-performance ecosystem for traditionally individual sport athletes. Gilmore highlights the need for remote programming and monitoring to support a constantly shifting roster. Together as a team, they navigate uncharted territory in action sports conditioning, guided by physiological demands and underlying energy systems. Gilmore and NSCA Coaching and Sport Science Program Manager Eric McMahon discuss the shift in sport science from ample to actionable data to find, change, and measure what matters most. Gilmore reflects on his “career periodization” and having free time for friends and family while working corporate hours — a stark contrast with his background in Major League Baseball (MLB). The pair also emphasize proactive networking and education for future career opportunities.
