Strength coaches build resilience in others, but sometimes life puts their own to the test. Katie Guillory, now Assistant Strength and Conditioning Coach at her alma mater, Louisiana State University (LSU), faced that test after a summer accident led to a below-knee amputation. As a former LSU softball captain with extensive knee and hip surgeries, Guillory explains her strong foundation for physical and mental recovery. For her, that means showing up and getting after it, even on hard days. Guillory encourages others to “act yourself into existence for a second,” believing that small, consistent steps — especially when motivation is low — are what build strong mindsets. Supported by the LSU community, she reflects on balancing relentless drive with vulnerability, accepting help, giving herself grace, and finding strength in connection. Her experience underscores that resilience is a lifelong mindset, reminding listeners that the same habits that build athletes can also rebuild their coach.

Sheri Walters’ journey to Director of Sports Medicine at Texas A&M University reflects a career defined by innovation, collaboration, and comprehensive integration. Walters discusses the "arms race" in collegiate athletics and how Texas A&M shatters silos through unit alignment and being intentionally present. Drawing from her EXOS experience, she highlights the impact of integrating sports medicine with strength and conditioning. Walters employs research-based cross-body training to maintain strength, prioritizing long-term rehabilitation over limb symmetry index testing. She explains how her Certified Strength and Conditioning Specialist® (CSCS®) and Certified Performance and Sport Scientist® (CPSS®) credentials enable her to elevate rehabilitation and speak the language of sport performance professionals. Walters underscores the importance of getting student-athletes back to team strength and conditioning as soon as tissues can tolerate it to promote physiological and psychological healing. She also shares how strength and conditioning coaches can optimize return to performance and reduce reinjury risk.
