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.
