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.

When William Kraemer first entered the field, strength and conditioning was, as he puts it, “primordial.” There were few standards, limited research, and little shared understanding. As one of the most influential figures in strength and conditioning, Kraemer recounts how the profession grew from humble beginnings into a science-driven discipline. That history still holds weight for coaches today. He explains why coaches are often drawn to new ideas, but progress comes from building on proven principles. Workout logs are central to his approach, and he notes how analyzing training over time can improve decision-making. He also emphasizes alignment across the performance ladder to support innovation and athlete development. As the Senior Advisor for Sports Performance and Sports Science at The Ohio State University, he shares his perspective on where the field is headed next. Apply his wisdom to stay grounded in solid principles, evaluate training with greater precision, and better serve your athletes.
