Yup, most people have weak cores from poor posture and sitting down all the time. Standing up has to engage your core and keep it stable. Literally dealing with a pulled back because I haven't done core strength in months. The difference is incredible.

But you need to engage core also when waking, otherwise your torso would dangle from your hips, no?

  It's much different when you start moving something and let it go with inertia vs when you keep it still against gravity. Compare moving your arm like a pendulum vs keeping it stretched horizontally.

  Try standing up for a few minutes, being mindful of what your body does. You will probably find that you lean slightly from side to side or stagger very slightly, with your core having to be partly engaged all the time. Your feet are in the same spot, but your center of gravity shifts and the core is the only thing to counter that. Meanwhile, when you walk, the momentum of your upper body takes care of a lot of this, you just automatically lean forward and your feet get under you, offloading a lot of that adjusting from your core. Your center of gravity moves predictably and your feet can "plan" to get right below it in the next step you take.

    Interesting! I would think keeping torso upright while walking would be engaging more muscles compared to standing, but I never studied this in detail, so you might be right. But then it's interesting that I sometimes have sore back after a run if I don't run for a long time while I haven't experienced this when standing yet. Maybe my running form is poor.

It is legs that gets tired and hurts from standing too much, not the core.

When I first moved to a standing desk, I was shocked that I (fit and healthy) couldn’t stand straight at the desk for more than an hour or two. Turns out I had what Dr YouTube said was an anterior pelvic twist (standing slouchy, belly out). Making myself stand upright was actually enough to give me an abs workout. I felt from standing the kind of “burn” you get after a load of crunches. Even now, a year later, I still have to work up to doing more than ~3 hours standing if I don’t stand consistently. So standing desks have a great for me. My one concern is that when tired or focused I subconsciously lean at weird angles and put pressure in the wrong places, but hopefully I move frequently enough.
