When I started using a H7 in February, having just started my fitness regaining quest, my typical resting heart rate while sitting was ~75bpm and just walking downstairs to the garage would send it north of 90.
The lowest I’ve seen since while sitting is 49bpm, typically while sitting it’s ~55, going to the garage now only raises it to ~75.
I often drink an awful lot of coffee, which doesn’t help quantify these readings.
I got the free “Elite HRV” app installed on my Android tablet, but I often forget to take a reading each morning and perhaps more importantly, I don’t think I’ve ever taken a reading after just waking up in bed while still lying down.
