In this episode, I’m speaking with Dr. Mike T. Nelson, a self-described research fanatic who has more than two decades of experience studying and obsessing over how the human body works.

Dr. Mike has a Ph.D. in exercise physiology, a master’s degree in mechanical engineering, and is an associate professor at the Carrick Institute and a university instructor at Rocky Mountain University. 

He’s also the creator of the Flex Diet and Physiologic Flexibility Certifications, has published research in both physiology and engineering scientific journals, and has even been asked to share his techniques with top military agencies.

Today, Dr. Mike and I go deep into the research and practical applications of heart rate variability. HRV has gained popularity as a performance metric, but after listening to our conversation, you’ll have a much broader understanding of HRV, how to apply it to your life (whether you’re athletic or not), and ways to improve your HRV score.
