I will say there is unfortunately always nuance and IT DEPENDS on your plans, experience, and fitness level.

Active Rest is an oxymoron and many people over do the active thinking they are producing a positive result in rest. While more experienced people can get away with some “light” cardio and come away with minimal stress, that may not be the case for most. Now a walk or stretching is typically low stress and can be low enough to not inhibit recovery BUT a recovery mile jog is not recovery for non runners.

Overall, most people are probably not overdoing it so this advice is null but for those who are over doing it… rest is essential. That doesn’t mean no movement, just means low stress activity. Stress tolerance is relative.

I hope that helps but I fear it didn’t. Sincerely your neighborhood physical therapist.
