Encouraging to hear the above comments! My husband's resting heart rate has dropped over the past year from low to mid 60's to an average, so far this month, of 56. I'd been told that "normal" was 60 to 100, so had wondered what was going on. Decrease in heart rate has paralleled his increasing fitness, which has recently been described by his trainer as very good for his age, which is 65. I know we are both fit these days, on a recently holiday, we were racing past young people in their 30's and 40's on steep hill walks!! Such an amazing contrast to two years ago, when he found staying awake a struggle, but then along came a diabetes diagnosis and low carb and everything changed.
