It's interesting. I did not like walking before lockdown. I mean, I'd occasionally do a proper all-day mountain walk, went tramping for 3 days in NZ but anything less than that, I turned my nose up at.
I like exercising, I run, do daily HIIT sessions, weights & walking wasn't intense enough.
I've changed completely since Covid. I love walking now. Short walk to break up the work day, realised I live close enough to beaches & absolutely love getting to one as much as I can (I've live here for nearly 20 years & managed to be unaware I was pretty close (with a drive) to beaches). I think I have learnt that everything doesn't have to be intense & exhausting, going sit a walk & chatting to someone, getting a coffee on the way, can be lovely.
I do like long walks tho, at least a few hours.
Eldest DC loves them too, younger two absolutely hate them but will occasionally concede.
Also, I've realised I sleep better after a decent walk, than say, a really tough cardio session. That might exhaust me but not in a relaxing sleepy way.
