The path to the top is not always linear. For Jill Costanza, it included returning to school and stops in collegiate and military performance before becoming Director of Sport Science and Assistant Strength and Conditioning Coach with the National Football League (NFL) Detroit Lions. Costanza describes today’s sport science landscape as a “Wild West,” where definitions differ by perspective. Her focus centers on assessing the athlete and program effectiveness against the demands of the game to identify holistic interventions. She outlines how intentional systems, a clear communication funnel, and data visualizations help athletes and stakeholders understand the “why,” build buy-in, and tap into competitiveness. Addressing common misconceptions, Costanza clarifies that elite athletes can still have foundational qualities that need rewiring. She emphasizes movement quality, proprioception, and breathing while adapting for individual needs and neurological fatigue. Learn how to build sport science systems, turn insights into action, and keep progressing on your professional path.

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.
