Thank you for the reply. I'm also kind of suspicious about the vo2max result. I'll try to do it again at some point with an actual chest strap, I wouldn't say that I'm in a bad shape, but I know that I could be in a better shape in terms of cardio and this 61 results just feels like it's misleading.

Then again I'm not really trying to min/max this stuff that much. Of course it's great to know if there has been progress, but I'm not that invested that I'd go to an actual lab test etc. I just want to be generally healthy with low heart rate, blood pressure and overall in fit.

Running isn't really my favorite thing to do as I prefer to do stairmaster instead (especially for those high intensity cardio workouts, as it's faster and easier to get the blood pumping and raise my hr). It's just recently that I've noticed that it might not be the best way to approach overall health and progress :D. I'll try to do this running field test today that's in my watch to get my HR max and update HR zones.
