If you want, you can try to target HR 5 bpm below AeT to be safe. But based on what you said, I don’t think it’s really a concern.
Is it okay to occasionally bump over your AeT by <5 bpms for just a few seconds. I had my long workout today and I noticed my HR jump above my AeT on a couple steep sections but it only went above for my AeT <30 seconds. Wondering if this doesn’t matter or if I should try to stay strictly below the entire duration of a workout. Thanks!
