🏃 Hardly David Goggins but did a 14 mile run today, could've done more energy wise but my lower back is bad which starts to cause hip tilt and can load the knees after running that long, no chance of bending down when I get back. Between Grok & YouTube it sounds like even people with lower back/disc issues can overcome this by strengthening your core and glutes with bird dog, dead bug, glute raises and some Mckenzie stretches to decompress. Dialling in running technique is an important factor as well, running tall, heel kick, lean from the ankles not the waste etc. Not uncommon to do 40 - 50 miles on the bike 🚴 but same happens again, too long sat on it and my lower back starts to scream, get home look in the mirror and my hips pelvis look lop sided (hip tilt) Supposedly it's your body's way of trying to protect your disc and nerves by pushing the spine to one side to avoid further aggravation but the imbalance loads up and stresses other stuff like your si joint.
