VO2max only tells you what would theoretically be possible, not what your body actually uses of it. And when it comes to pinning down your second lactate threshold, not even the 72 recognised models can agree.
A test shows you WHAT a body can do. A diagnostic shows you HOW it does it. Why that difference decides whether your Zone 2 is actually a Zone 2.
My watch went for a swim in a fountain and invented roughly 100 metres of climbing. obseed now corrects errors like this automatically, including in your old sessions.
obseed now breaks your session into five-minute slices and shows the temperature curve instead of a single average, with a heat load reading per slice and honest gaps wherever the data does not reach.
A watch does not measure your VO2max, it estimates it. Why that estimate is surprisingly good for recreational athletes, and why it misses for the very best.
Whoop says rest day, Garmin recommends threshold training. Why wearables contradict each other, and why picking your measurement method matters more than asking who is right.
obseed now lets you attach real sport-nutrition products to each training session — capturing the exact carbs, sodium, caffeine, and calories you took in, right next to what you burned.
What HRV really measures, why your nervous system sets the tempo, and why twenty seconds before you hit start decide the data quality of an entire session.
obseed now offers a personal iCalendar feed — subscribe once to see your sport sessions, competitions, and sleep in Apple Calendar, Google Calendar, or Outlook.
On many Garmin watches HRV recording is off by default and gets reset by firmware updates. Here is how to enable it so obseed can analyse your heart rate variability.
Your daily tags now become visual heatmaps. obseed weekly and monthly views reveal supplement gaps, sickness arcs, and caffeine rhythms at a glance.
91 Oura tags flow automatically into obseed — correlating with Garmin, Whoop, Withings, and Wahoo. No double entry. No silos. Your full picture.
