Just for shits and giggles, I decided to check my resting heart rate. I had been riding my bike as a daily commute, averaging 25kph to work and 22kph from work, and I wanted to see if there was a benefit to all this bike commuting.
According to topendsports, an average resting heart rate of someone 35-40 years old is 71-75 bpm.
My resting heart rate prior to re-starting my bike commute was about 70bpm (and I was 37 at the
time), which put me right around average, maybe slightly on the border with "above average." As a point of reference, my resting heart rate when I was a vasity swimmer in high school - at 16 years of age - was 47 bpm, which put me well within the athlete level.
Now, it's not surprising that resting heart rate will increase with age, but moving from an athlete level to average means that I knew what it was like, and 70 bpm seemed really fast. But now, my resting heart rate is roughly 55 bpm, which works out to being on the upper end of "athlete" for a man in my age category.
And that feels nice.
Maybe it is also time to check my BMI (with recognition of problems of height and muscle density) and my blood pressure?
