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.

Sam Moore’s path into sport science is defined by taking risks and chasing meaningful questions. After a devastating knee injury as a collegiate athlete, Moore not only returned to compete, but she also discovered her calling in strength and conditioning. She recounts her coaching, sport science, and hybrid roles prior to leaving a full-time position to pursue her PhD at the University of North Carolina at Chapel Hill. Moore describes sport science as problem-solving and drawing evidence across disciplines to drive innovation. She discusses her research on female athlete availability in elite settings, including nuances like body composition, recovery, and high speed exposure in training. Moore advises young professionals to remain open-minded, pitch their ideal position if it does not exist, and go “all in”— knowing one decision does not define forever. Whether you are a coach or researcher, this episode delivers real-world insights on navigating your career with courage and curiosity.

Gaining a key perspective on what is happening not only in the market, but also in the fitness industry as a whole, can provide owners and managers with the insight necessary to uncover the data and trends for their business to thrive.

Unfortunately, injuries do occur during exercise, and the legal implications that follow them can be quite significant. Taking small, reasonable precautions at the onset of a new personal trainer-client relationship can stave off significant problems down the road.

One the fastest growing trends in the fitness industry over recent years has been the increase of personal training studios. Learn how to identify the varied services that can be offered at the personal training studio, and how to promote and sell in a layered pricing format.
