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.

Lindsey Kirschman sees her non-traditional educational background as her greatest asset, not a detriment. She still considers herself a teacher — just differently — as the Director of Sports Performance for University of Utah women’s basketball. Coming from a family of educators, Kirschman initially studied forestry and range science before pursuing strength and conditioning. Kirschman explains how her teaching experience provided a firm foundation for optimizing learning and creating a positive environment. Her approach promotes skill transfer from the weight room to sport and beyond, using exercises like sled pushes as analogies for life lessons about resilience. A former track athlete, Kirschman underscores that while the finish line is the same, every athlete’s starting point is unique. Kirschman also discusses culture building through her “GOAT Award” and the challenges of transitioning from a generalist to a specialist. She encourages aspiring professionals to reframe their mindset and fully engage with their working environment.
