This sounds to me like a case of creating then solving your own problem. You define “maximising every minute of your day” for yourself, feel the pressure to follow it then you tell yourself another story to break out of it. Great. It could be even better if you have defined “maximising every minute of your day” differently. To me, maximising every minute of my day isn’t working. It means being present for each moment and taking as much value out of it as possible (as opposed to mindlessly passing life by or being constantly distracted). It doesn’t imply intensity. It implies absorbing. So it doesn’t matter if you’re in the gym or not as long as you’re present for it. No shaming on anyone who takes their physique seriously either.
