This episode challenges common perceptions about exercise, delving deep into the benefits of vigorous exercise for not just physical health but also brain function, aging, and even cancer prevention. It tackles fundamental questions, like what genetic and metabolic adaptations occur with vigorous exercise and how it can contribute to combating heart's age-related changes. We also unpack how these rigorous exercises affect glucose transport, mitochondrial health, and brain health at an intricate level. Lastly, it introduces practical applications like the Norwegian 4x4 interval training protocol, the benefits of "exercise snacks," and how to incorporate vigorous-intensity exercise into everyday life.
In this episode, I discuss:
(00:00) Introduction
