Lower back pain is one of the most common complaints I hear — from yoga students, from training clients, from people who sit at desks all day and from people who are physically active. It’s estimated that up to 80% of adults will experience significant lower back pain at some point in their lives. And yet, for most people, the back itself is rarely the primary problem.

Understanding what’s actually happening is the first step to fixing it.

The Back Is Usually a Victim, Not a Villain

In the majority of non-traumatic lower back pain cases, the lumbar spine is compensating for problems elsewhere in the movement system. The two most common culprits: inadequate hip mobility and weak core musculature.

When the hips don’t move well — whether due to tightness, weakness, or poor motor control — the lower back picks up the slack. Every time you bend, lift, or rotate, the spine is asked to do more than it’s designed for. Over time, that repeated compensation creates irritation, inflammation, and pain.

Similarly, when the deep core muscles — particularly the transverse abdominis, multifidus, and pelvic floor — aren’t engaging properly, the lumbar spine loses the stable foundation it needs. It becomes a moving segment trying to do the work of a stable one.

The Role of the Hips

Hip mobility is consistently underrated in back pain discussions. The hip joint is designed for significant range of motion in multiple planes. When that range is restricted — through prolonged sitting, previous injury, or simply lack of use — the body compensates by finding motion at the lumbar spine instead.

This is one of the core principles in movement assessment: the body will always find a way to get the motion it needs. If it can’t come from the hip, it comes from the back. If it can’t come from the thoracic spine, it comes from the neck. Restriction at one joint creates compensation at the next.

The Core Stability Problem

“Strengthen your core” is the most overused and least understood piece of advice in fitness. Most people interpret it as doing crunches. Crunches are a flexion exercise targeting the rectus abdominis — useful, but not what the lower back needs.

The core muscles most relevant to lumbar stability are the deep stabilizers that create intra-abdominal pressure and hold the spine in a neutral position under load. These muscles don’t flex your spine — they resist movement. Training them requires anti-flexion, anti-rotation, and anti-extension exercises: planks, dead bugs, bird dogs, Pallof presses.

A strong rectus abdominis with a weak transverse abdominis is like having a powerful engine in a car with no chassis. The power is there. The structure to channel it is not.

What Actually Helps

Hip mobility work — 90/90 hip stretches, hip circles, deep squat holds, and pigeon pose with active engagement address the restrictions that force the lumbar spine to compensate.

Glute activation — the glutes are the primary movers of hip extension. When they’re underactive, the lower back takes over. Clamshells, banded walks, glute bridges, and single-leg deadlifts wake them up.

Anti-movement core training — dead bugs, bird dogs, and side planks build the stabilizing capacity the lower back depends on.

Movement pattern retraining — learning to hinge at the hip rather than rounding the lumbar spine is one of the highest-value interventions for back pain. A properly loaded hip hinge strengthens the posterior chain and takes stress off the spine simultaneously.

When to See Someone

Most lower back pain is mechanical and responsive to movement-based intervention. But pain that radiates down the leg (sciatica), is accompanied by numbness or tingling, follows trauma, or doesn’t respond to conservative management warrants evaluation by a healthcare provider. Rule out structural causes before treating mechanically.

The Bottom Line

Your lower back is most likely trying to tell you something about your hips, your core, or your movement patterns — not about the back itself. Address the system, not the symptom. Move more, move better, and give the lumbar spine the support it’s been compensating without.
