The term "Zone 0" is being introduced as a low-intensity movement that barely feels like exercise but still carries health benefits. This type of activity can help regulate blood sugar, improve circulation, ease stress, and support mental clarity. However, while Zone 0 is a powerful foundation for building longevity and resilience, it is essential for a balanced approach to building VO2 max, which is linked to lower risk of cardiovascular disease, metabolic disorders, and all-cause mortality. The author suggests that to build this intensity, a balanced, balanced approach is needed to balance Zone 0 with high-intensity training. For example, walking slowly after a meal can significantly lower blood sugar levels compared to sitting, which reduces your risk of insulin resistance and type 2 diabetes. However the author also suggests that for longevity, exercise should involve challenging movements that challenge your heart, lungs, and muscles in ways slow movement can't.
