Joel Jamieson is a conditioning expert who developed Morpheus to give people a smarter way to build their conditioning regimen and improve their recovery. In this episode, Joel dives deep into the world of heart rate variability (HRV), explaining its scientific foundation, how it measures the balance between the sympathetic and parasympathetic nervous systems, the various methods of measurement, and how it can guide healthier lifestyle choices and improved training performance. He explores the nuances of HRV calculation, the impact of aging on HRV, and the roles of genetics, exercise, and other lifestyle factors in this process. He also covers Morpheus, the innovative training tool that won Peter over after his initial skepticism, highlighting its practicality and effectiveness in guiding training and optimizing fitness outcomes.
