Mike Joyner is a physician-researcher and one of the world’s leading experts on human performance and exercise physiology. In this episode, Mike discusses how to combat age-related declines in health and fitness levels by using various modes of exercise to improve lifespan and healthspan. Mike explains the impact of exercise on the autonomic nervous system, blood pressure, heart rate, heart rate variability, heart rate recovery, and max heart rate. He dives deep into VO2 max, including how it’s measured, what is driving it, and how to improve it. Mike provides training insights for the average person, including training volume and exercise intensity as well as simple metrics to track. Furthermore, he gives his take on the theoretical “J-curve” relationship between exercise and longevity, as well as whether possible health dangers may be associated with excessive exercise.
