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.

Most law enforcement officers are physically taxed, mentally exhausted, and emotionally overwhelmed. As such, a complexity exists with a requirement to match the need for physical fitness in a demographic that lives their lives in a potential state of general exhaustion.

This article builds upon two other client assessment tools (breathing and posture, as seen in Personal Training Quarterly Issues 5.3 and 6.1, respectively) and discusses ways to assess client movement.

The purpose of this article was to conduct a process evaluation of a six-week recruit strength and conditioning programming for rural structural firefighter recruits.

You can’t talk about strength and conditioning without Coach Boyd Epley. Regarded as the “Godfather of Strength and Conditioning,” Epley laid the groundwork for the profession and later founded the NSCA in 1978. His 10 Husker Power Principles, developed at the University of Nebraska, remain a cornerstone in programming and formed the basis of sport-specific training. Emphasizing strength and power, Epley implemented testing and debunked the prevailing belief that weightlifting hindered speed. He recounts his journey with co-hosts Eric McMahon and Jon Jost, chronicling how a pole vault injury and exposure to bodybuilding led him to become the first collegiate strength and conditioning coach. What began with cement bars and paint cans evolved into a fully equipped weight room and impressive lifelong career. Additionally, Epley’s open-door policy — even with his fiercest competitors — helped drive the profession forward. This episode is a must-listen for anyone interested in strength and conditioning history. Explore the University of Nebraska’s Husker Power Principles discussed in this episode.

This article explains the potential benefits of microdosing training with tactical athletes.

An organized, science-based, and evidence-based periodized program that is guided by capable and competent professionals is the most efficient and effective way to accomplish the task of returning from a shoulder injury to full active duty. The concepts of periodization paired with evidence-based strength and conditioning interventions provides the framework needed for tactical facilitators to accomplish this task.
