I started using a Heart Rate monitor. At rest, I'm below 70 bpm. When cycling I'm between 150 and 160 almost every time I look at it.
I'm a little suprised it's not more variable. Even when climbing hills, the rate changes very little. It will drop below 150 bpm if I'm stationary for three or more minutes.
I'm 53 years old and 210 lbs @ 6' even.
How can I better understand what this data means?
