How do I prevent lower back pain from standing too long at a sit-stand desk?

Lower back pain from extended standing is very common and usually caused by muscle fatigue and pelvic tilt changes as you get tired. The fix is to limit continuous standing to 20–30 minutes before transitioning to seated, and to invest in a quality anti-fatigue mat (3/4"–1" thick with a beveled edge). Shifting weight from foot to foot, using a footrest rail to periodically raise one foot, and wearing supportive footwear all significantly reduce fatigue.
