Since 1998, Bryan Mann has dominated strength and conditioning, securing positions at elite collegiate programs and defining research in strength, power, and velocity-based training (VBT). As the Academic Director of Strength and Conditioning at Texas A&M University, Bryan still gets the rewarding chance to shape students like his former athletes, but now, he’s focused on the future. He’s expanding his scope to human performance as a whole — applying his coaching expertise to advance performance across general, special, and tactical populations. Join NSCA Coaching and Sport Science Program Manager Eric McMahon as we follow Bryan’s professional path, including his recent transition to the Aggie’s powerhouse performance staff alongside Bo Sandoval and Tommy Moffit.

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.
