If health, performance and longevity, are in your game-plan, physiology fitness must not be overlooked. Building robust physiology translates to body systems what they need in the way of energy, oxygen and “clean-up” for all systems to operate at 100% for years and years to come. These systems include the autonomic nervous system, the cardio-respiratory system, the gastrointestinal system/microbiome, the muscular/skeletal system, primo vascular system and especially our mitochondria. Mitochondria, like the microbiome are symbiotic organisms within the human body whose health we must take care of if we expect them to take care of us.
