I exercises like a fiend yet your slavish adherence to logging and scrutinizing these numbers sounds exhausting in comparison. Are you a world class athlete trying to shave .02 seconds off a 10K? If not, try just going outside for a jog or mountain bike with some friends and go home and relax once. I bet your biometrics end up the same, if not better, and you don't even need to check.

I wonder how the accurate the biometrics even are on things like smarth watches ?

[tpm]

Many (even recreational) athletes use accurate measurements (heart rate chest bands, power meters integrated into bike cranks, ... continuous glucose monitors).

[noitpmeder]

Sure they use them, but almost definitely for infinitely small marginal benefit... Despite what the manufacturers of those products want you to believe.

[tpm]

They are used to measure performance, not to enhance it, so there is no performance benefit. But if the athletes want to have that information, who are we to judge them? I just use Strava with GPS (no HR monitor, no powermeter or anything else) and I am pretty sure the stats keep me engaged and I would be doing less physical activities without them. If it works like this for someone using their powermeter, why not?

It's fun to watch numbers go up. No-one thinks that watching numbers go up makes them go up faster. (It probably makes them go up slower in the long run (lol), by encouraging short-term thinking and planning.)

[idiotsecant]

That's pretty condescending. For some people the data is not just a means to an end. Its an end itself.
