Episode notes

When blood arrives to muscles, it has oxygen. The more capillaries that you build into those muscles, the more oxygen available to those muscles. So this long duration work is really about building the capillary systems and the mitocondria within the muscles themselves. It's very good at using energy sources within blood.

This episode I discuss endurance: our ability to perform effort over extended amounts of time. I describe the four kinds of endurance: muscular endurance, long duration (single-set) efforts, and the two kinds of high intensity interval training (HIIT). I discuss efficiency of effort and maximizing quality of effort, and a hydration formula. I review how our heart literally gets stronger when we oxygenate muscles properly. I also discuss motivation for long bouts of work and the visual physiological basis of the "extra gear" we all can leverage for effort. Finally, I review how accelerating as we fatigue can allow us to access untapped energetic resources.
