As I indicated in my recent post, Do You Have a Healthy Heart?, I am interested in determining if exercise can improve heart rate variability (HRV). Over the past month, I have made daily measurements in order to establish a baseline for future comparisons. Below are the details of what I am measuring.
Each morning after I wake up, I measure my resting heart rate using a Suunto t6d heart rate monitor. I first measure my resting heart rate in a seated position for three minutes followed by a three minute measurement in a standing position. From each three minute window, I isolate a one minute segment to analyze and record. Continue reading

Most everyone knows that a low resting heart rate is a positive indicator of a healthy heart, one that is capable of moving blood around the body in an efficient manner . In fact, some world-class athletes, Lance Armstrong for example, have resting heart rates as low as 32-34 beats per minute where the average person is more likely in the 60s or 70s.
However, resting heart rate is only a small part of the story (as I have recently discovered).
“When you lose flexibility and responsiveness, you die. Perhaps the most spectacular example of this is heart-rate variability, i.e. the amount by which the heart rate alters from beat to beat. This is, possibly, the single most sensitive indicator of a healthy heart, and a loss of beat-to-beat variability is one of the most powerful single indicators of the risk of dying of heart disease.” From The Great Cholesterol Con by Dr. Malcolm Kendrick
