What Do Nerves Need?

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.
