The measuring stick in this article seems to solely concerning the resting heart rate. Yes, this is because that is the origin for the 10k/day measure; but, surely there are other benefits regardless of what intensity a workout you have.

- brandonb 11y agoYep—resting heart rate is a good proxy, and readily measurable from Apple Watch. A definitive study would randomly assign people to an exercise routine, follow them for 20-30 years, and then measure hard outcomes like heart attacks, strokes, and all-cause mortality. Since that's pretty challenging, all of the studies on exercise (and nutrition, for that matter) make two types of approximation: 1. analyze correlations in data rather than randomize, and/or 2. analyze proxy metrics like resting heart rate or blood pressure rather than hard endpoints. That's part of what makes research on health so complex!
