Why Your Back Hurts All the Time (And It's Probably Not Just Your Mattress)

You didn’t injure it. There’s no single moment you can point to. It’s just been there, low-grade, for months, and you’ve started assuming it’s “just getting older.” Before you accept that, it’s worth knowing that a few specific, common, fixable habits cause most of this — not age itself.

The usual suspects, roughly in order of how common they are

• Sitting for most of the day, especially in a car or at a desk. Prolonged sitting shortens your hip flexors, which pulls on your lower back and changes how it’s loaded even when you’re standing. This is probably the single biggest contributor for most desk-job or long-commute men.
• A weak core, specifically the muscles that stabilize your spine, not the ones that show up in a mirror. Your lower back compensates for a core that isn’t doing its share of the work, and compensating constantly is exactly what turns into chronic ache.
• How you pick things up, on autopilot, dozens of times a day. Not just the gym — grabbing a kid, a bag, a box off the floor while slightly twisted. These small, repeated bad-mechanics moments add up more than any single “injury.”
• Sleeping position and pillow setup — genuinely can matter, but it’s usually a smaller factor than the other three, not the main cause it gets blamed for.

What actually helps, in the order to try them

1. Move more during the day, not just at the gym. Standing up every 30-45 minutes, even just for a minute, does more for chronic back pain than an occasional intense workout that a sedentary day undoes.
2. Build the specific stabilizing muscles — planks, dead bugs, bird dogs. Boring, unglamorous, and more effective for this specific problem than heavier back-focused lifts.
3. Fix your lifting mechanics deliberately for a couple weeks until it becomes automatic — hinge at the hips, keep the object close, brace your core before you lift anything, every time, even something light.
4. Stretch hip flexors specifically, not just your back — a simple kneeling hip flexor stretch, held daily, addresses the actual source more directly than back stretches alone.

When it’s not just this

Get it checked by a doctor if the pain is sudden and severe, radiates down a leg, comes with numbness or weakness, or doesn’t respond at all to a few weeks of the above. Most chronic, low-grade back pain is mechanical and fixable with consistent habit changes — but ruling out something else is worth doing rather than assuming.
