Few strength coaches have shaped sport performance like Al Vermeil — the only strength coach to earn championship rings in both the National Football League (NFL) and National Basketball Association (NBA). In this Gatorade Performance Partner Special Episode, Vermeil shares how a career built on explosiveness, adaptability, and relentless curiosity has transformed teams at every level. From advancing plyometrics and Olympic lifts in the 1970s to creating the performance pyramid and the innovative “time machine” testing system, his methods have influenced generations of coaches and athletes worldwide. Known for blending timeless principles with fresh, actionable ideas, he explains how mechanics, group management, and collaboration create consistent results and lasting trust. Along the way, Vermeil offers rare perspectives on coaching longevity, revealing how his adaptability and curiosity have kept him learning — and lifting — into his 80s. Gain practical insights to keep explosiveness central, integrate performance science, and strengthen your long-term coaching impact.

Squash demands speed, strength, and control at the edge of human range — but still suffers from a massive stigma around heavy lifting and underuse of strength and conditioning. Brigita Roemer is leading the shift as Director of Strength and Conditioning for U.S. Squash, where she oversees all off-court physical development. After suffering a devastating injury as a track and field athlete, she discovered strength and conditioning when a biomechanics team “put [her] back together,” setting her on a linear path in the profession. Assigned to a sport she had never heard of before, Roemer began by emphasizing injury risk reduction, full range of motion, and “strength at length” to meet squash’s extreme movement and deceleration demands. With frequent connective tissue injuries like sprains and strains, athlete availability remains a top concern. By prioritizing continuing education and building relationships, Roemer has helped U.S. Squash make history — on the path to LA 2028. Connect with Brigita on Instagram: @brigey_lux | Find Eric on Instagram: @ericmcmahoncscs and LinkedIn: @ericmcmahoncscs Elite strength and conditioning pros like Brigita Roemer rely on NSCA events to stay sharp, grounded, and connected.

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.

Your career can accelerate when you ask, offer, and say yes. For Morgan Smith, that approach led to a postdoctoral fellowship with the Wu Tsai Human Performance Alliance at Stanford University. Smith recalls how coaching sparked her interest in the science behind performance. Working across academic and practical settings, she encountered challenges with research feasibility firsthand. Today, she focuses on blending coaching with sport science. At Stanford, she began by building relationships and trust within the athletic department. She describes collaborating with coaches and staff to identify research interests, gaps, and low-burden contributions. Smith also highlights opportunities to support club sports, campus recreation centers, and community programs. These roles can help fund education while building your resume, network, and practical skills. She reinforces the value of education as a time to maximize experience and explore interests. Discover how to gain applied experience early, drive cross-department buy-in, and cultivate relationships that move your career forward.

Building athletes who are strong, healthy, and resilient requires more than sets and reps, starting with a shift in mindset. Christi Edson, Head of Performance for the Orlando Pride in the National Women’s Soccer League (NWSL), shares how she integrates strength and conditioning with sport science to sustain athlete health and performance. She reflects on the field’s evolution from the well-known “Bigger, Faster, Stronger” program to a training culture emphasizing resilience, active recovery, and durability. Drawing from her experience coaching high school athletes to NWSL professionals, Edson highlights the adaptability and creativity coaches need. Those qualities help her to develop athletes who can thrive through a demanding 11-month season. She details how tools like GPS, force plates, and velocity-based training sharpen communication and reshape expectations in the gym. Her story points coaches toward the future of athlete development: collaboration, precise load management, and long-term health as the foundation of strength.
