Heart rate zones can't change manually

Please note that there are up to four different HR Zone tables - the general one, and the separate tables for Running, Cycling, and for  Swimming. Make sure you are changing the relevant one. Also note that if you base the table on the percentage of the Max HR, LTHR, or RHR, then the absolute values will change if the base value changes. Imported activities may come with their own HR Zone table. 

Hello, thank you for your quick response. As I mentioned above, I changed them both in general and in each of the sports (swimming, running and cycling) I used MAXHR% as a measurement. But the zones on the BPM still do not change. As an example, my upper limit based on MAXHR% of Z2 is 150 BPM. and I see both during the activity at fenix on the Z2 MAX watch 139 BPM and when downloading the activity in the app the same thing... Can you think of another solution?

Not sure if I understand, but keep on mind that changing the table will not change the past activities retrospectively. Each change of the zones will only influence the future activities.

If you changed the table before the activity, then please post a screenshot of the respective HR Zone table, and another screenshot of the Times in Zones of the concerned activity (done after the HRZ table change).

As far as I see, everything fits perfectly:

• your Max HR is 198 bpm
• Z1 - 50% of 198 is 99 bpm
• Z2 - 60% of 198 is 119 bpm
• Z3 - 70% of 198 is 139 bpm
• Z4 - 80% of 198 is 158 bpm
• Z5 - 90% of 198 is 178 bpm

All of that matches exactly the bpm values in the activity table Time in Zones. Where exactly do you see a problem?

Ok, you are right, now do you know how I can do or what information to enter so that the areas are like this manually? since it doesn't let me edit cads area by BPM Pd:I attached a print (karvonen method) 

I do not know where the table you posted comes from, but it is definitely wrong. Use the calculator, and you will see that their percentages do not match the absolute values at all. For example 90% of 198 bpm is definitely not 182! It is 178, just as Garmin correctly calculates. So maybe you should simply stop relying on someone who is not even capable to calculate the percentages

... but looking at it again, I see your table is actually not using the Max HR as the basis of the table, It is using the HR Reserve. So just use the same basis on Garmin's side, and you'll be fine.

For example:

37 + 90% of (198 - 37) = 182 

Anyway, the best method to get the right zones table corresponding to your physiology in the best possible way, is neither the Max HR, nor the HR Reserve basis. It is the LTHR based table. Assuming you have a reliable LTHR value - either from a lab, or from the Self Guided Lactate Threshold Test available on your watch (you have to use a HRM chest strap, though).

Ok, the best method is doing an FTP and of course LTHR as you told, which one I done (FTP). Afterwards, the mathematical calculator of karvonen is well known in the world and excelent for most high endurance athletes. 

well, I found the solution. I had to change the measurement to %FCR and adjust a couple of maximum points only (FCRMAX). I also had to reset the zones (50/59-60/69, etc.) and then it worked perfectly for the Karvonen example that I sent you. Thank you very much for your time anyway.
