Vigorous exercise delivers a louder physiological signal to the body, resulting in an exponential increase in benefits for various health outcomes like cancer, blood glucose, and cardiovascular adaptations.

“the overall signal is just louder. And it's not just a matter of, oh, you burn twice as many calories, so it's twice as good for your health. No, you're this. You can't really quantify it. It's an exponentially better increase for X outcome that you're looking at this physiological mechanism. It's an exponential increase when you up that intensity.”
