Dr. Brian Cole’s podcast explores heart rate variability (HRV) as a crucial metric for assessing the body’s readiness. HRV measures the variation between heartbeats, controlled by the autonomic nervous system. Chronic stress leading to low HRV can harm the cardiovascular system, while high HRV is linked to improved focus, calmness, and overall well-being. Regular physical activity and fitness contribute to a healthy heart and high HRV. Tracking resting heart rate also indicates fitness and well-being.
