If you’re over 35 and dealing with nagging low back pain that just won’t quit, you may have heard your physical therapist or doctor mention your “posture” or “core strength.” But there’s often a more specific issue at play—one that doesn’t get talked about enough: the loss of your natural lumbar lordosis.
In our years of treating people with back pain, we’ve noticed a pattern. Time and time again, when someone comes in with chronic, nagging low back pain, their lower spine has lost its natural inward curve. Instead of a healthy lordosis, we see a flattened—or even reversed—curve in the lumbar spine. And more often than not, this pattern has been building for years, sometimes made worse by exercises intended to help.
The good news? Once you understand why this curve matters, you can start taking real steps to restore it—and finally address the root cause of your pain instead of just managing symptoms.
What Is Lumbar Lordosis, Anyway?
Your spine isn’t meant to be a straight line. It’s designed with three natural curves that work together like a spring: a slight inward curve at your neck (cervical lordosis), an outward curve in your upper back (thoracic kyphosis), and an inward curve in your low back (lumbar lordosis).
This S-shaped design isn’t a flaw—it’s engineering brilliance. Those curves allow your spine to absorb shock, distribute load evenly, and support your body weight efficiently through movement. When all three curves are present and balanced, your muscles can do their job properly, your discs are under more even pressure, and your whole trunk works as a coordinated system.
When the lumbar lordosis gets lost—flattened by years of sitting, poor movement habits, or even well-intentioned exercise choices—that balance is disrupted. Muscles that are supposed to support your spine passively now have to work overtime. Discs bear pressure unevenly. And pain often becomes the body’s way of saying, “something isn’t working right here.”
Why Are So Many People Losing This Curve?
There are a few common culprits we see in our practice:
Prolonged sitting. Modern life keeps most of us sitting for hours at a time—at desks, in cars, on the couch. Sitting naturally encourages a flattened low back, and over time, your body can adapt to that flattened position as its “new normal.”
Fear-avoidance patterns. When back pain flares up, many people naturally guard against movement that seems to aggravate it, often the extension motions that emphasize the lordosis curve. Over time, avoiding these positions can decondition the muscles that would normally maintain that curve.
Well-meaning but incomplete exercise programs. This is a big one we want to focus on today.
The Problem With “Just Do Posterior Pelvic Tilts”
If you’ve been to physical therapy for back pain before, there’s a good chance you were taught the posterior pelvic tilt—tucking your pelvis under to flatten your low back against the floor or wall. You may have also been given a series of flexion-based exercises: knee-to-chest stretches, seated forward bends, or exercises that round the lumbar spine.
We understand why this approach is common. Flexion-based exercises and posterior pelvic tilts can feel good in the short term, especially during a painful flare-up. Rounding the low back can temporarily take pressure off certain structures and provide quick relief.
But here’s the problem: if this becomes your primary long-term strategy, you may be training your spine to move further away from its natural, healthy curve—not toward it. Instead of restoring balance, repeated flexion-based movement and pelvic tucking can reinforce the very flattening pattern that contributed to the pain in the first place.
Avoiding pain isn’t the same as fixing the problem. Short-term relief strategies, when used as long-term solutions, can leave the underlying imbalance untouched—or even make it worse over time.
What Should We Be Doing Instead?
Rather than chasing pain relief through flexion alone, we believe in helping people restore balance throughout the entire spine. That means:
Rebuilding awareness of the natural curve. Many people have simply forgotten what a neutral lumbar lordosis feels like. Relearning this position is often the first step.
Strengthening the muscles that support extension. The muscles along your low back, glutes, and deep core stabilizers are meant to help maintain that curve actively throughout the day—not just during exercise.
Improving mobility in the whole spine and hips. Sometimes limited hip mobility or stiffness elsewhere in the spine forces the lumbar region to compensate by flattening. Addressing these areas can take pressure off the low back.
Gradually reintroducing extension-based movement. Under proper guidance, safely reintroducing extension can help retrain the spine to move through its full, balanced range—not just the flexed positions that feel “safe.”
This is exactly the kind of comprehensive, whole-spine approach we focus on for people managing chronic back pain. It’s not about doing more of what feels good right now—it’s about building a spine that’s resilient for the long run.
Ready to Address the Root Cause of Your Back Pain?
If you’ve tried physical therapy before and found that the relief never seems to last, it may be time for a different approach—one that looks at your whole spine, not just the flexion patterns that offer temporary comfort.

The Bottom Line
Your lumbar lordosis is supposed to be there. It’s not a problem to be flattened away—it’s a feature to be protected and restored. Chronic back pain often isn’t a sign that your spine needs less curve; it’s often a sign that it needs more support to maintain the curve it was designed to have.
Restoring balance takes time, patience, and the right guidance, but it’s absolutely achievable at any age. You don’t have to keep managing pain with short-term fixes. You can address the underlying pattern and build a stronger, more resilient back for the years ahead.
