NATE CORTEZ

Performance Trainer | Nutritionist | Combat Sports Specialist

My name is Nate Cortez. I’m a performance coach and nutritionist through ISSA im passionate and dedicated to optimizing athletic potential through intelligent training, functional nutrition, and combat sport–specific conditioning. With a foundation in strength and conditioning, and applied nutrition, I combines evidence-based programming with a deep understanding of human movement and metabolic performance.

Over the past decade, I have trained and competed in several disciplines Mixed martial arts, boxing, Dutch kickboxing I have worked with fighters, competitive athletes, and general population clients to enhance strength, speed, and endurance while improving recovery and injury resilience. My approach integrates performance periodization, metabolic conditioning, and individualized nutrition strategies—tailored to body type, movement mechanics, and sport demands.

As a combat sports performance specialist, I apply a hybrid methodology that blends boxing, mixed martial arts conditioning, and functional strength systems such as conjugate, triphasic, and GPP training. Programs are built to develop complete athletes—powerful, efficient, and technically while maintaining joint health and longevity.

My philosophy centers on movement quality, metabolic health, and mindset. Whether guiding an athlete through a fight camp, a weight cut, or a body recomposition phase, I deliver structured systems that build both performance and sustainability
