Low Back Pain When You Squat: The Hip and Ankle Fix

Your low back hurts when you squat.

And every time it happens, you wonder if you should just stop squatting altogether.

I'm here to tell you the squat isn't the problem. The way you're squatting, with the body you have today, is the problem. There's a difference.

I'm Dr. Jason Han, doctor of physical therapy and sports rehab specialist. I run HealthFit Physical Therapy and Chiropractic in Pasadena, California, and a big chunk of my week is spent with lifters who love the squat — back squat, front squat, goblet, you name it — and whose low back keeps tweaking on them.

Today I want to walk you through how I actually look at this in the clinic, what I look for, what I fix first, and why "just stop squatting" is almost never the right answer.

The framework: source vs. cause

The framework I use for every joint pain conversation is the same: source versus cause.

The source is where it hurts. In this case, your low back.

The cause is what's actually driving the pain.

In a squat, the cause is almost never the low back itself. The cause is somewhere else in the chain — your hips, your ankles, your thoracic spine, the way you load the bar, your programming.

Most people only treat the source. They stretch their low back. They roll their low back. They put ice on it. They hope for the best.

And the pain keeps coming back, because the cause is still upstream, doing its job. Until you fix the cause, the source will keep complaining.

Three joints, one rhythm: the mechanical principle that runs the squat

Here's the mechanical principle that runs the entire squat.

In a clean squat, your spine should stay neutral while your hips, your knees, and your ankles move together at the same time.

I mean that literally. At the same time.

If one moves before the other, the chain goes out of sync, and the load you were trying to share across three joints gets dumped onto whichever joint is doing the most. A lot of times, that joint ends up being your low back.

People don't realize how subtle this is.

If your hips break first, your spine has to bend forward to chase them, and your low back takes the load.

If your knees shoot forward first, your ankles run out of room, your hips stop moving, and again the low back gets it.

Three joints, one rhythm. That's the goal.

The old cue that makes it worse: "arch and look up"

Here's a cue you've probably heard your whole lifting life. When you back squat, arch your low back. Look up. Eyes on the ceiling.

I get where it came from. People were trying to keep lifters from rounding forward into a flexed spine under heavy load.

But the fix overshoots in the other direction.

When you arch your low back hard, you're not in a neutral spine anymore. You're in extension. When your neck is craned up looking at the ceiling, that's also extension.

Here's the part that gets missed: when your neck is in extension, it's actually really hard to recruit your abs. And without your abs firing, you lose the bracing that protects your low back under the bar.

So you end up with a posture that looks "tight" and "strong," but you're stacking the load right onto the very tissue you were trying to protect.

Try this instead

  • Eyes forward, not up.

  • Chin slightly tucked, not jutted.

  • A neutral neck helps you keep a neutral spine.

  • A neutral spine lets your abs do their job.

  • Your abs doing their job is what actually protects your low back when the weight gets heavy.

It's that simple, and it's that important.

Asymmetry: the hidden driver of low back pain in lifters

When somebody squats in front of me, I'm not just watching the bar go down and up. I'm looking at asymmetry.

  • Are you leaning a little toward one side as you descend?

  • Is one knee diving in while the other tracks fine?

  • Is one hip sitting back further than the other?

Most lifters have no idea they're doing this. It's invisible until you film yourself, or until somebody points it out.

Asymmetry is one of the biggest hidden drivers of low back pain in lifters.

You think you're squatting both legs evenly, but really one side is doing seventy percent of the work, and the other side is along for the ride. That uneven loading shows up in your low back, because the spine is the bridge between two halves of your body. If one side isn't pulling its weight, the spine is what compensates.

The split squat regression: the move I reach for first

This is one of my favorite tools.

When somebody walks into the clinic with low back pain from squatting, I rarely have them keep grinding double leg back squats while we figure things out. I move them into split positions instead.

A split squat. A rear foot elevated split squat. A reverse lunge.

Same hip, knee, and ankle pattern. Same training stimulus. But the demand on the low back drops dramatically, because you're loading one leg at a time and you don't need a heavy barbell across your spine to get a real training effect.

Now I can actually train your hip mechanics, your knee tracking, your ankle mobility, one leg at a time, and clean up the asymmetry I saw on your double leg squat. Then, when the chain is moving in sync and the asymmetry is gone, we bring you back to the double leg lift if that's what you want to do.

A lot of lifters resist this. They feel like splitting back means they're going backwards. But you're not. You're moving sideways to fix what the back squat was hiding. When you come back to the bar, you come back stronger and more symmetrical, and the low back stops complaining.

Load and programming: the conversation nobody wants to have

Here's the harder conversation.

A lot of people are just living too heavy for what they can actually do. Their squat numbers got them in the door. Their squat numbers are also breaking them.

If you're not strong enough to do the volume of reps you're doing at the weight you're using, you're not training. You're surviving.

And the higher the weight goes, the more your programming has to be dialed in — not just how many reps in a set, but how many sets, how many sessions per week, how much recovery between heavy days.

This is where it can actually get dangerous. Heavy weights don't punish you on the rep that breaks you. They punish you on the cumulative load nobody was tracking.

Before we talk about anything fancy, the first question is always: is the weight on the bar honest for the body you have right now?

Sometimes the answer is no, and the fix is simply rebuilding from a smarter starting point. That's not weakness. That's longevity.

The cause: hips, ankles, and the thoracic spine

Now let's go back to the cause.

Stiff hips

If your hips don't move well, your low back picks up the slack. You can't get into a deep squat with a neutral spine if your hips can't get there. Something has to give, and it's the lumbar spine.

Stiff ankles

If your ankles don't have the dorsiflexion to let your knees travel forward, your hips can't sit back the right way, and your low back compensates.

Locked thoracic spine

If your thoracic spine — your upper back — doesn't have enough extension, then to get the bar racked across your shoulders or to keep your chest up under load, you have to arch from the low back instead. That arch isn't strength. That's a borrow. You're borrowing motion from a segment that wasn't designed to give it, and the bill comes due.

Same squat. Same weight.

Mobile hips and ankles and a mobile thoracic spine? Your low back stays quiet.

Stiff hips and ankles and a locked thoracic spine? Your low back is the only thing left to give. So it does. And it pays for it.

This is why "just stop squatting" misses the point. The squat is exposing the cause. The squat isn't creating it.

When the source is the source: regenerative therapy from Day 1

Now sometimes the source is the source.

There's actual tissue in the low back that's part of the story — disc irritation, facet joint stress, early degeneration, even some sciatic-type symptoms running into the leg. When that's the case, treating the cause alone isn't enough. The tissue itself needs care.

This is where regenerative therapy comes in for us, and I want to be clear about how we use it.

At HealthFit, regen isn't something we save for later. It isn't a salvage tool. It isn't a reward for failing at PT first. It's part of the healing stack from Day 1. Hands. Exercise. Regen. Working in parallel.

For the low back, that means we can target the actual irritated tissue with our regenerative tools — Extracorporeal Magnetotransduction Therapy, focused shockwave, and radial pressure wave — while we're cleaning up the cause upstream.

  • Extracorporeal Magnetotransduction Therapy (EMTT) is the foundation. It re-energizes the tissue at the cellular level, drops the chronic inflammation that's been blocking healing, and resets the cells so they can repair.

  • Focused shockwave goes precisely where the damaged tissue lives, and stimulates the body to remodel it.

  • Radial pressure wave handles the broader soft tissue around it — the muscles, the fascia, the surrounding system that's been overloaded.

This isn't bolted on at the end. It's woven into how we treat from the start, because tissue healing deserves real tools, not just hope that exercise alone will fix it.

So while you're learning to squat better, we're also healing the source, in parallel. That's how recovery actually compounds.

The bottom line for any lifter with low back pain

The squat is not your enemy. The squat is a stress test that exposes whatever in your body isn't doing its job.

Source versus cause is the lens.

  • Get your hips, your ankles, and your thoracic spine moving the way they were designed to move.

  • Get your spine neutral, your neck neutral, your abs braced, your chain moving in sync.

  • Be honest about your loading and your programming.

  • And if the tissue in your low back is part of the story, give it the real care it deserves — from Day 1, not as a last resort.

Do all of that, and the low back stops being the limiting factor in your training.
