Suunto ZoneSense

@flo7z simply put - as I understand it - HR zones are not static but will shift up and down depending on your current condition. ZoneSense takes that into account.
So if you wanna train “classical Zone 2”, you use the green ZoneSense zone. If you wanna go harder use the yellow or red accordingly. -
@flo7z This is the point! Just because your HR is constant does not mean your fatigue is constant. The reason to use ZS is to measure effort in real time. Too many think that HR zones are set in stone. Before ZS I knew my HR would change depending on workouts done prior and how I felt. But I had no idea how much my HR zones could change. ZS matches my RPE very well. Since watching all videos and reading the peer-reviewed scientific manuscripts on ZS (I am a Professor of Molecular and Cellular Biology) I trust ZS for my training and trust RPE more than before. On off days I would think it was my mental state but now I know it was likely fatigue.
