Hi @DaveMeney ,
by accident i posted the follow up in a wrong thread.
You can follow up here:
Like @Alex said, power zone 2 is not equal to heart rate zone.
My findings so far with the PZ2 Training:
Slowly raising HRV, slowly lowering RHR.
My HR Zone up there has changed already, since Whoop calculate them based on Max HR and HRR (heart rate reserve) HRR results out of: Max HR - RHR = HRR.
Therefore, lowering RHR increase the HRR which lower the entry level for the different HR Zones also.
Before i started cycling, my HR Zone 4 started at 166 BPM now its starting 161 BPM.
This is an observation, i honestly have no idea if its good or bad but it feels good!
Greetings!
