I'm convinced that most of these are due to the lack of back muscle development. Muscles which would normally stabilize your spine as you move are too weak to do so, so things get screwed up. I had really bad back problems in my mid-30s. They all went away when I started lifting weights. Took me a while to even get to a point where I could lift _anything_ without back pain in fact. Initially lifting 60lbs off the ground would cause pain - an embarrassing fact for a heavy-set 6'2" male. After a year and a half of consistent progress I topped my deadlift out at 525lbs. I decided not to go further, since I don't compete, and I'd need to buy more plates and a different bar for my barbell. I haven't had any back pain ever since. The worst part of the situation is, nearly 100% of the doctors will tell you not to do back strengthening exercises beyond the bullshit you typically see at your PT office, which really does nothing to make you stronger. I do not advise most people to lift as much weight as I do, but you gotta give that posterior chain a good workout at least once a week, and the best way to do so is by squatting with a barbell and doing deadlifts. The loads can vary, do as much as you're comfortable doing.
