Vigorous exercise, especially high-intensity interval training, is one of the best ways to

Well SupportedHigh-intensity interval training (HIIT) forces adaptations in mitochondria, leading to increased mitochondrial biogenesis.

Partially SupportedMetabolic stress induced by high-intensity interval training (HIIT) increases lactate levels, which signals PGC-1α activation, promoting the growth of new mitochondria.

Partially SupportedAn increased number of mitochondria over time improves muscle oxygen utilization, blood sugar management, and reduces oxidative stress.

Partially SupportedShort bursts of intense exercise can improve metabolism, protect against age-related muscle loss, reduce inflammation, and boost overall health.
