Movement does more than burn calories, it changes how your cells create energy. âĄď¸
Exercise stimulates mitochondrial biogenesis, the process of building and improving the mitochondria responsible for producing cellular energy. Research shows that both endurance and interval exercise can increase markers of mitochondrial biogenesis and improve metabolic function.
The takeaway? Consistent movement is one of the most powerful ways to support energy production, metabolic health, and resilience.
And when exercise feels unusually difficult or fatigue persists despite doing âall the right things,â it may be worth asking why.
