Lower back pain after deadlifts is almost always caused by modifiable factors — not by the deadlift being inherently dangerous. The most common culprits are rounding of the lower back under load, a posterior chain that fatigues before the set is finished, restricted hip or upper-back mobility that forces the low back to compensate, and adding weight or volume faster than your tissues can adapt. In most cases the fix is correcting how you perform the lift, not abandoning it.
First, the reassuring part: the deadlift probably isn’t the problem
The deadlift has a reputation as a back-wrecker, but the research tells a more nuanced story. The lower back is one of the two most commonly reported injury sites among people who lift weights, and when pain shows up it is most often tied to the squat or the deadlift — yet overall injury rates in strength training are low compared with most field and contact sports. The takeaway is not “deadlifts are dangerous.” It is that the deadlift loads your spine in a specific, demanding way, and small problems with technique, capacity, or programming get magnified under that load.
Done well, the deadlift is one of the most useful tools you have for building a resilient back. The pain is a signal worth understanding — not a reason to give up the lift.
The six reasons your low back hurts after deadlifts
Pain that shows up specifically after deadlifts (and not after your other lifts) usually traces back to one or more of the following. They frequently stack on top of each other.
1. Technique and spinal position — the most common culprit
The deadlift is unforgiving of positional errors because it loads the lumbar spine, discs, and ligaments in ways most other lifts do not. In the clinic, this is the category we end up correcting most often. The patterns we see again and again:
- Lumbar rounding under load. The lower back flexes during the pull off the floor or through the mid-lift, sharply increasing shear forces on the discs and ligaments — and it gets worse as the back extensors fatigue late in a set.
- Over-arching at lockout. Snapping into excessive extension at the top to “finish” the lift jams the facet joints of the lower back.
- A poor setup. Hips starting too high turns the lift into a back-dominant movement; the bar drifting away from the shins increases leverage on the spine; weak lat engagement lets the bar swing forward.
- Under-bracing. Without enough intra-abdominal pressure and a rigid torso, the spine has to absorb motion it shouldn’t.
Notice how many of these get worse with fatigue. That is why pain so often appears on the last reps of a set or the last set of a session, as form quietly breaks down.
2. Loads that exceed what your tissue is currently ready for
Heavy deadlifts generate shear and compressive loads at the lower lumbar segments (typically L4–L5 and L5–S1) that can exceed recognized injury thresholds — with the highest demands occurring right at lift-off and at lockout. Repeating reps amplifies the risk, because fatigue progressively increases trunk flexion and shifts more of the load onto passive tissues. The issue is rarely the load in isolation; it is the load relative to what your back is currently prepared to handle.
3. Posterior chain endurance and strength gaps
Weak or quickly-fatiguing back extensors (the erector spinae and multifidus), glutes, and hamstrings leave the lumbar spine doing work it isn’t built to do. Endurance matters as much as raw strength here — a back that is strong for one rep but fades by rep eight will start compensating exactly when the load is heaviest and your guard is down. This single factor is one of the strongest predictors of how your back responds to deadlifting (more on that below).
4. Mobility restrictions
If your hips, ankles, or upper back (thoracic spine) can’t move through the range the lift demands, the lower back makes up the difference — usually by rounding under heavy load. Tight hamstrings and hip flexors are common offenders that quietly sabotage an otherwise good hip hinge.
5. Load management and recovery
Adding weight, volume, or frequency too quickly, skimping on the warm-up, or training while under-recovered all set the stage for pain. This often shows up as soreness that lingers longer than it should rather than a single dramatic moment.
6. Pre-existing or one-sided issues
Sometimes the deadlift simply exposes something that was already there — a mildly irritated disc or facet, or an old strain — that the movement provokes more than anything else you do. Pain on only one side often points to a technique asymmetry or a side-dominance pattern. Individual proportions (limb and torso length) also change your leverage and can make the standard pull less forgiving for some lifters.
A quick endurance test that predicts how your back will respond
We use a simple back-extensor endurance test (the Biering-Sørensen test) in which we have you hold your upper body horizontal, in a plank position, off the end of a bench while we support your hips and legs — then we record how long you can hold it. The hold time reflects how well your posterior chain resists fatigue — the exact quality that breaks down on a heavy set of deadlifts.
Why it matters for you: in research on deadlift-based rehabilitation, baseline performance on this test was the single strongest predictor of who improved. Lifters with solid endurance and moderate pain tend to do well progressing the deadlift; those with low endurance usually get better results building the engine first before loading the pull heavily. It’s one of the simple, low-cost checks we use at Performance Sport Care to decide whether a lifter is ready to load the deadlift or needs to build capacity first.
The counterintuitive part: deadlifts can fix the very pain they’re aggravating
Here is the part most people don’t expect. The strongest evidence in this entire area is that progressive, well-coached deadlift training reduces pain and improves function in people with mechanical low back pain — when it’s started at the right load and the person has adequate posterior chain endurance to begin with. In one program built around the deadlift, roughly two-thirds of participants reported a meaningful reduction in pain at the one-year mark.
That flips the usual advice on its head. For most recreational lifters, the answer to deadlift-related back pain isn’t to stop deadlifting forever — it’s to fix the loading, rebuild the capacity, and earn the lift back.
What we do if this is you
When a lifter comes to Performance Sport Care with this exact complaint, here is how we work through it:
- We watch you move. We film your setup and pull from the side, because most positional faults are obvious on video even when they don’t feel obvious to the lifter mid-set.
- We test capacity, not just symptoms. Endurance checks like the Biering-Sørensen test tell us whether your posterior chain can currently meet the demand of the lift or needs to be built up first.
- We pinpoint the actual driver — technique, endurance, mobility, or an irritated structure — and rule out anything that calls for a different level of care. Generic “core work” rarely solves it; the fix has to match the cause.
- We develop a custom rebuild plan. This may involve reducing the load and volume to what you can properly and safely perform. If your low back pain persists or if you fail to improve, we re-evaluate you and adjust our treatment plan or rehab plan accordingly.
The evidence is consistent on one point: the best outcomes come from expert clinical supervision plus progressive loading. We want to help you benefit from deadlifts, if possible, not avoid them. We’re serious about this work, and we’re good at it. We measure ourselves by one thing — whether our patients get better. That’s the difference we set out to make.
Why lifters bring this problem to Performance Sport Care
Most advice for back pain is written for people who don’t train. We are built for the ones who do. Performance Sport Care is a sports chiropractic and supervised strength-rehabilitation clinic in Walnut Creek — and treating people who want to stay strong is the whole point of the practice.
Our approach is deliberately different from the two things that usually fail lifters:
- We diagnose first. Before any plan, Dr. Cancel determines whether your pain is driven by technique, a capacity or endurance gap, restricted mobility, or an irritated structure — because the correction is completely different in each case.
- We provide an expert treatment and rehabilitative strengthening plan. Recovery happens through careful guidance under Dr. Cancel’s direct clinical supervision, with the goal of returning the deadlift into your training routine as an enjoyable benefit — not something you avoid and quietly lose.
That’s a far cry from adjustment-only chiropractic, and from the rest-and-medicate routine that sends lifters home, only to have the same pain return on the next heavy pull. As a former national-level competitive bodybuilder with more than three decades working with strength athletes, Dr. Cancel speaks your language — and that matters most if prior care elsewhere hasn’t held.

Frequently asked questions
Is it normal for my lower back to hurt after deadlifts?
Mild, short-lived muscular fatigue can be normal, especially after you have increased load or volume. Pain that is sharp, lingers more than a couple of days, or recurs every session is a signal that something in your technique, capacity, or programming needs attention.
Should I stop deadlifting if my back hurts?
Usually not permanently. For most recreational lifters the better move is to back off the load, fix the problem factors, and rebuild — research shows progressive deadlift training can actually reduce mechanical low back pain. Stop and get assessed if the pain is severe or radiates into a leg.
Why does my back hurt after deadlifts but not squats or rows?
The deadlift loads the lower lumbar segments through a hip-hinge pattern with shear and compressive forces that other lifts do not reproduce in the same way. A position or capacity gap that other lifts tolerate gets exposed under the deadlift specifically.
How do I tell normal soreness from an injury?
Soreness is diffuse, achy, eases with movement, and fades within a day or two. Pain that is sharp or localized, worsens, lingers, or travels down a limb is not ordinary soreness and warrants evaluation.
What is the most common deadlift mistake that causes back pain?
Rounding of the lower back under load, usually combined with under-bracing. It increases shear on the discs and ligaments and tends to get worse as the back extensors fatigue late in a set. Starting the lift with the hips higher than the torso also places the lower back at risk.
Can deadlifts actually help my back pain?
Yes, in many cases. The strongest evidence in this area shows that supervised, progressively loaded deadlift training reduces pain and improves function in people with mechanical low back pain who start at an appropriate load.
How long should I rest before deadlifting again?
Rest intervals are based on individual factors such as training experience, observed recovery, training load, or the presence of pain or discomfort. When in doubt, perform deadlifts less frequently in your training rotation and take advantage of the greater recovery and strength this affords.
Do I need an X-ray or MRI for back pain after deadlifts?
Most deadlift-related low back pain is mechanical and does not require imaging. Imaging is reserved for cases with specific warning signs or pain that does not respond to appropriate care, which a clinical evaluation determines.
When should I see a professional?
If your pain is severe, keeps recurring, lingers beyond a few days, radiates into a leg, or comes with any unusual symptoms — or if you simply cannot find the cause on your own — a careful, expert, and thoughtful professional examination will save you time and repeated flare-ups.
