Hello,
I’m confused about low heart rate training Zone and which zone is meant with it. My 23 heart rate zone ends at 130bpm. When running in that zone it is very relaxed. According to the MAF formula my low heart rate zone ends at 142bpm. This is in the upper part of Z3 aerobic Zone. That BPM is don’t consider low heart rate when running.
Isn’t “low heart rate zone training” done at Z2? Or am I missing something?
To make it even more confusing, my Garmin watch suggest to do base training with a 138bpm HR which is another value. Which zone makes most sense to use for my base runs and why?
According to my Garmin my Z3 starts at 131BPM. According to MAF my heart rate should be below 142BPM. So even 10BPM then the MAF limit is in my Z3.
In my opinion, something is wrong with your Garmin Zones.
How is your garmin calculating Zones?
so check that Max. and Rest HR are correctly set and change them if needed
My best guess is your Maximum HR is set wrong (too low). Look in your training logs what’s your max HR in some intense activities, and considering some unaccurancies you can make a good stimation of your Max HR. This applies IF you do some intense runs/exercise. You need to go hard for some minutes. At your age, unless some unlikely conditions, you should reach about 180 bpm.
Max HR is set to 185bpm, Z2 is set to 60-70%, so upper limit is at 130. That is correct.
