   Credibility Through Shared Suffering: Guillermo Blanco on Leading Soldiers #61

   In this episode, I sit down with Guillermo Blanco, Tactical Strength and Conditioning Coach and one of the many professionals helping shape the future of the Army's Holistic Health and Fitness (H2F) program. With nearly 15 years of experience spanning collegiate athletics, private sector coaching, and tactical performance, Guillermo brings a unique perspective on what it takes to build stronger, more resilient soldiers. We discuss his transition from collegiate strength and conditioning into the tactical environment and the culture shock that comes with coaching soldiers instead of athletes. Guillermo explains how he learned to adapt training programs to units with limited equipment and resources while still driving meaningful results. One of the most powerful parts of the conversation centers around credibility. Guillermo talks about participating in training events alongside the soldiers he coaches, embracing the discomfort and hardship with them rather than coaching from the sidelines. He explains why earning trust is critical to success and how shared experiences help build relationships within a unit. We also discuss his move from Fort Bragg to Fort Campbell, the differences between supporting Field Artillery units and Infantry formations, and the lessons he's learned working with different military cultures and command teams. Guillermo shares his thoughts on what separates a good H2F coach from a great one, how to successfully navigate relationships with both troops and leadership, and why communication is often as important as programming. Beyond coaching, we dive into Guillermo's decade-long journey as a competitive powerlifter, the challenges of balancing performance goals with family life, and how he manages the demands of being a husband, father, coach, and athlete. This is a great conversation about leadership, credibility, tactical performance, and finding balance while pursuing excellence.

   In this episode, I sit down with Nick O'Brien, a Tactical Strength and Conditioning Specialist with Air Force Special Operations Command (AFSOC), a national-level strongman competitor, a Highland Games athlete, an Army Reserve officer, and the host of The Strength Game Podcast. We dive into the world of tactical strength and conditioning, discussing why physical readiness remains one of the most critical components of combat effectiveness and how the military can continue to improve how it develops and sustains human performance. Nick shares his perspective from years spent coaching collegiate athletes and now helping optimize performance within the special operations community. We also talk about our shared passion for strongman, the lessons learned from competition, and the realities of training through injuries while pursuing elite-level performance. Nick opens up about the challenges he has faced during his own strongman journey, how setbacks have shaped his approach to training, and why resilience is often the defining characteristic of successful athletes and operators alike. Beyond the weight room, we discuss leadership, coaching philosophy, the future of tactical performance, and what it takes to build stronger, more durable warfighters for the demands of modern conflict. Whether you're a coach, athlete, service member, or strength enthusiast, this episode is packed with insights on performance, resilience, and the pursuit of excellence.
