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?

    In my opinion, something is wrong with your Garmin Zones.

    How is your garmin calculating Zones?

    Garmin fitness devices assign heart rate zones based on your maximum and resting heart rates set in your user profile

    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.
