Our Training Pillars

Nasal Dominance

Unlock Your FULL Potential

If you haven't disciplined yourself to nasal breathe during the most intense portions of your training and racing, you have yet to reach your potential.  In all my years of training and racing, we are only NOW starting to understand and embrace the profound effects of nasal breathing in exercise performance. 


Nasal breathing isn't just a fundamental physiological process; it's also the optimal strategy for unlocking your full potential in every aspect of exercise & fitness training. Whether you're engaging in endurance activities, steady-state training, or speed-based workouts, nasal breathing offers unparalleled benefits. By breathing through the nose, you enhance oxygen uptake, improve lung function, build CO2 tolerance, and optimize the delivery of oxygen to working muscles, leading to increased stamina, reduced fatigue, and enhanced endurance.  I'm preparing you for the future as an athlete who combines having a big motor and getting great gas mileage. 


Beyond its application in specific training paradigms, nasal dominance is the perfect strategy for fitness enthusiasts of all levels, regardless of their exercise routine. Whether you're hitting the gym, practicing yoga, or enjoying outdoor activities, nasal breathing enhances performance, promotes recovery, and contributes to overall health and vitality.

Diaphragm Muscle

Your Powerhouse Muscle


Ed Harrold advocates for a paradigm shift that centers around the often overlooked powerhouse of the body: the diaphragm. Despite being the primary muscle responsible for breathing, the diaphragm remains vastly underutilized in conventional fitness approaches. However, Ed emphasizes that harnessing the full potential of this muscle is essential for optimizing athletic performance. A strong diaphragm not only enhances respiratory function but also serves as a stabilizer for the core, contributing to improved posture, balance, and overall strength. Through nasal breathing, which engages the diaphragm fully, individuals can train this muscle effectively, unlocking a myriad of benefits. From enhanced oxygenation and endurance to increased energy efficiency and reduced risk of injury, a strong diaphragm lays the foundation for peak athletic performance. Join Ed Harrold in redefining fitness training by prioritizing the development of this vital muscle and experiencing the transformative impact it can have on your athletic endeavors.

The Lungs

Train Respiratory FIRST

Ed's approach begins with the foundation of training the respiratory system FIRST allowing this to be the driver of cardiovascular and neuroskeletal muscular conditioning. At the core of his philosophy lies the recognition that optimal performance stems from a balanced and efficient respiratory system. By prioritizing nasal dominance and understanding lung physiology, Ed empowers individuals to maximize their potential while maintaining harmony with the autonomic nervous system. Through nasal breathing, he teaches how to tap into the body's innate ability to regulate stress responses, promote relaxation, and enhance endurance. Furthermore, Ed emphasizes the importance of utilizing fat as the primary source of fuel, a key aspect in achieving sustained energy levels and metabolic efficiency. By integrating these principles into training regimens, individuals can cultivate a balanced approach to fitness that fosters peak performance, resilience, and overall well-being.
