I definitely went on this journey with my running. At first I would run very short distances at very high pace(zone 4/5), but I fell out of it. I picked up running again last year and ended up more in zone 3/4, but for the last six months I've been aiming for zone 2 in most of my runs.
I've had some knee pain recently so I've not been running much, focusing instead on knee strengthening exercise. On my last run I discovered this weird phenomenon were my knees stopped hurting if I ran faster with longer strides, it felt like I was "rolling through" each step which seemed less demanding for my knees. Perhaps my slow running style is just poor.
Rucking. Get a back pack with a chest and waist strap, put in weights (increase over time) or buy a cheap weight lifting belt (Velcro fine) and attach a rope and something that drags (I use an old wheel).
Low impact, good for core strength. Zone 2 approved.
If you are wealthy they make specific back packs or I bought a tacti-cool one on Temu for cheap.
Outlive by Peter Attia is pretty good for more ideas on how to lengthen the mobile portion of your life.
I've noticed that, too. This video is interesting: https://www.youtube.com/watch?v=Jj9ZgQgQvBk and might explain some of it, but I also think that the kinematics of your legs works better at higher speeds (or at walking speeds) - jogging seems the worst for joints!
The youtuber "knees over toes guy" seems to be largely acknowledged by The Internet as having a novel, free and effective way to strengthen and injury-proof your knees. Worked very well for me.
