Why do your muscles burn during exercise? It is not what you think.

The burning sensation during intense exercise is often attributed to lactic acid, but this is a surface-level explanation. Looking at the body through the lens of energy potential and circuit dynamics, lactate acts more like a pressure release valve for electron overload. Understanding muscle fatigue requires looking at energy resistance and how the body manages flux when mitochondrial capacity is exceeded. This discussion from episode 260 covers the physics of fatigue and why the brain interprets these physiological signals the way it does. Watch the full episode on the Mind & Matter YouTube channel for the deep dive on energy resistance.
