I no longer regularly jog / run / cycle, only occasionally for pleasure. I either swim or hike steep hills or if weather is ugly just put treadmill on 15% incline and walk very fast for an hour or so. Wastes energy like crazy and leaves my knees intact.

I think diversifying the physical activities is a good thing.

Also avoiding using your domotics, motorized vehicles, elevators and escalators, kitchen/cleaning robots/electric devices when there are manual replacement as well as not using domotic, does a super job on its own.

People have become lazy, pretend they don't have time to do stuff, then have to actually dedicate additionnal time so that their body doesn't suffer from their lazyiness. This is bonkers.

One day my brother saw me shirtless and asked me if I was going to the gym. I said no, I just have 2 young kids, carry my groceries including cat litter by foot, use a shovel to clear snow, use a manual coffee grinder and kitchen whisk and only use my car when it would take me more than 1 hours / 30kms by bicycle, etc. And I had an office job. Being active, fit and healthy shouldn't involve having to "exercise".

There is the downhill part of the hikes, unless you have ski lifts or similar way of getting down. I used to do running a bit before major paragliding accident, and I hiked like there is no tomorrow and still do... subjectively the hiking down part felt more stressful on knees than running (maybe not on concrete/tarmac).
