I had a "below average" VO2 max score based on my Apple Watch measurements. It was ~40 mL/kg/min, in the span of about a month it jumped up to 53 mL/kg/min, which is "high" for my age group. So what happened? I started running instead of cycling as my primary form of cardio.

My hypothesis is that the apple watch estimates higher if you are running rather than pedaling. I definitely don't think my cardio vascular went from poor to great over a month. It seems more likely that it was maybe underestimating, and perhaps now is overestimating.


After a long injury, I got back to slowly running on the treadmill/bike/elliptical at the gym. IIRC, my garmin qualified its VO2Max results by saying I needed to run out side for some period of time to get a more accurate measurement. I guess there is something about the running metrics it collects that has a smaller error range.

Yeah I just ignore it, when I was biking 40+ miles a week this summer it says my VO2 max was 18, which is just absurd. Maybe because my arm is really hairy I don’t know.

There are many tools that accomplish static analysis in python. mypy is the original, but pyre(meta), pytype(google), and pyright(microsoft) are alternatives which make different trade offs.


Acknowledge that you have a want to check things, and set aside a dedicated time to do so. That way you aren't haphazardly checking things while you are free, and you can limit the effect work has on your vacation. Worse than working on vacation is feeling bad about working on vacation.
