Join 📚 Leerentveld Readwise Highlights

A batch of the best highlights from what Niels's read, .

The score is a hint, not a measurement. What you can genuinely track sits underneath it, and three things are enough for that. • Look at the raw values: nightly HRV and resting heart rate appear as a number in almost every app. Compare them against your own history, not against a norm. • Learn your range: write the values down for a few weeks. Then you know how much they normally swing for you, and you only react once one leaves that band for several days. • Ask four questions: sleep, fatigue, stress, muscle soreness, each 1 to 7. Thirty seconds of effort. Background on this: [RPE, the marker no watch measures](https://www.thefitfuturist.com/en/training-analysis/physiological-foundations-ai-training/). That leaves the question that actually comes up in practice: what do you do when the number and how you feel point in different directions?

Is There a Readiness Score? Yes, Fourteen of Them

people don’t pay attention to boring things (Brain Rule #4). You’ve got seconds to grab someone’s attention and only 10 minutes to keep it. At 9 minutes and 59 seconds, something must be done to regain attention and restart the clock—something emotional and relevant.
