I took a 60 mile bike ride yesterday in perfect weather, much of it on a beautiful forest road, and afterwards I was exhausted and it took a huge amount of effort even just to feed myself, and it was totally impossible to summon any motivation to spend 5 minutes to do the dishes afterward. I've been riding a bike for a decades, have crossed continents by bike, and have bike commuted my entire career pre-COVID. I slept pretty well and feel healthy and energized today and doing the dishes was easy this morning, but it's totally contrary to my entire life experience to claim that doing something physically tiring gives you more energy afterward. Not that doing nothing all the time feels good— humans just don't have unlimited capacity for output. Taking a leisurely morning walk (or a moderate-distance bike commute) certainly gets my day started on the right foot, but going harder faster longer at physical activity makes me physically tired and less capable of doing other things.
