Drawing on evolutionary biology and the latest research, Dr. Sinclair traces physical activity back millions of years, explaining how humans evolved for endurance, why modern sedentary life creates a profound mismatch with our biology, and how exercise activates ancient cellular pathways involved in repair, resilience, metabolism, and longevity. Dr. Sinclair breaks down what happens inside the body when we exercise, including the molecular responses that help us adapt to stress and influence the brain, immune system, metabolism, cardiovascular health, and even the way our cells age. He also tackles some of the biggest questions in exercise science: Can exercise offset sitting all day? Do we compensate for calories burned during exercise? Why did humans evolve such extraordinary endurance? And could exercising with others provide benefits beyond physical fitness? From our evolutionary past to the molecular machinery inside our cells, this episode reveals why movement is so deeply embedded in human biology – and why staying active may be one of the most powerful ways to keep that biology working as we age. __________________________________________ Partners of the Lifespan show help us keep this program freely available as an educational resource while also supporting medical research.
