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.

As a Strength and Conditioning Coach with the US Olympic & Paralympic Committee (USOPC), Jared Siegmund prepares athletes for the apex of achievement and perseverance. Siegmund shares that, contrary to public belief, the Olympic competition cycle is not every four years — Team USA athletes face fierce competition in World Series events along the way to qualify. He also speaks to the creativity required to coach Paralympic athletes, where missing limbs create unique biomechanics and hearing or visual impairments impact cueing. Siegmund touches on his principles-based programming architecture, sample adaptations, and USOPC’s interdisciplinary support team. Additionally, Siegmund and McMahon discuss the new generation of modern athletes who are more in tune with data and can control their preparation experience.
