For a long time, it was assumed that fatigue was a muscular phenomenon. It was thought be a set point and once you hit it, you couldn't go any further—like running into a wall. However, more recent research has showed that it's actually much more of mental phenomenon. Our brain shuts us down before our body does, in order to protect us from injury, exhaustion, or even death. (See: Tim Noakes's central governor theory and Samuele Marcora's model of fatigue, both of which we discuss in today's episode.) This presents us with an interesting conundrum: We have to get to know our fatigue extremely well, so that we know how to navigate all the signals it's sending us. Knowing when to ignore your brain's warning signs, and when to heed them, has far-ranging consequences for everything from endurance sports to creative work. So today we're teaching you the steps to help you learn how to dance with your fatigue.
