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.

Growth happens when you go all in, or as Brittany Wiebe says, “full send.” As Head Strength and Conditioning Coach of women’s basketball at the University of Oregon, she shares her people-first, evidence-based approach to maximize performance, minimize risk, and positively impact each individual. Using reverse engineering and fundamental principles, Wiebe describes programming around the big seven movements, progressive overload, and objective and subjective feedback. She reflects on her path through Kenya, Dubai, and the Dominican Republic, gaining exposure to athletes across sports, backgrounds, and abilities. Logistical challenges, like language barriers and limited resources, strengthened her adaptability and creativity. Wiebe believes weight room culture starts the moment you walk in. Her strategies — from high-energy greetings to rallying around big lifts — remind coaches that intent begins with environment. She challenges coaches to step outside their comfort zones, say “yes” to opportunities, and bring the same intensity to their development that they demand from athletes.
