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.
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.
