A lot of practitioners misunderstand the value and assessment of the infrasternal angle (ISA) to determine effective interventions that restore respiratory variability. While you’ll see changes in the extremes of wide vs. narrow ISA with effective interventions, physical structure determines the appearance (wide or narrow) and the available compensatory strategies that may be limiting movement capabilities. Here […]

Foundations: Building Resilience

January 25, 2017 By Bill 1 Comment

Perceived threat to a self-organizing system will result in simplification of the system to reduce degrees of freedom and response time while simultaneously sacrificing adaptability. Humans will shift into the sagittal plane to reduce the degrees of freedom to simplify movement creating a more stable state. This will reduce system complexity and cortical effort and […]

You have to earn your way into the 16%. To do so, we must think differently. Fitness training is young and indecisive. Rehab is stagnating. Strength & Conditioning is being stifled by tradition and confusion. It's time to do the work necessary to improve or join the average.
