In the last Q+A podcast there was a question about Suunto Zonesense, which uses realtime HRV data, which I had not heard of before so I did some research. If it works as described, it displays in real time on your watch whether your current intensity (with slight lag) is below LT1, between LT1 and 2, or above LT2. And it supposedly dynamically adjusts throughout the workout accounting for fatigue. And it also learns each sport/activity from your data knowing, as Evoke often says, that each sport’s zones are a bit differerent from each other. Sounds a little too good to be true but Suunto has some videos showing data and real world examples. Much of this aligns perfectly with the Evoke philosophies. Any Evokers try this?
