Why Golfers Get Lower Back Pain

A note before anything else

I am a performance coach, not a clinician. Nothing here is a diagnosis, and it is not a substitute for one.

If you have pain that wakes you at night, pain that travels down a leg, numbness, weakness, or anything that followed a specific injury, see a doctor or physiotherapist first. That is not a formality — those patterns need assessing properly, and training around them without knowing what they are is a bad idea.

What follows is about the far more common case: the golfer whose back tightens up over eighteen holes, or aches the morning after a long practice session, and who has been told there is nothing structurally wrong.

The lumbar spine is not built to rotate much

Your low back has a limited rotational budget. Estimates vary, but it is a small fraction of what a golf swing demands. The rest is supposed to come from the hips and the thoracic spine.

When those two contribute properly, the lumbar spine mostly transmits force rather than creating motion. When they do not, it gets recruited into a job it was not designed for — and it does it, because bodies are accommodating. It just does not enjoy doing it repeatedly at speed for twenty years.

So the question is rarely what is wrong with your back. It is usually what is not happening above and below it.

The three patterns I see most

Early extension. The pelvis moves toward the ball through the downswing and the spine extends to make room. It creates compression at exactly the moment the swing is fastest. It is also strongly associated with limited hip internal rotation, which is why the fix often has nothing to do with the back.

Side bend into impact, sometimes called the reverse C. The trail side collapses and the lumbar spine takes a combined extension and side-bend load. This is a position many golfers can hold comfortably once and cannot tolerate five hundred times a season.

Under-rotating up top. When the thoracic spine will not turn, the backswing gets shorter and the golfer makes up the difference by rotating the pelvis further or throwing the arms. Both push load somewhere it should not go.

None of these are swing faults in the coaching sense. They are what a body does when it is asked for a shape it cannot make, and that is why swing lessons alone often fail to shift them.

What I change first

Not strengthening. That surprises people who arrive expecting to be told their core is weak.

The first thing is usually volume and intent. If you are irritated, the fastest relief often comes from reducing the number of high-speed reps for a couple of weeks while we work on how the load is distributed. That is a hard sell to a keen golfer, but it buys the room to change something.

The second is rotational literacy — teaching the hips and mid-back to take back their share. This is where the mobility work earns its place, and it frequently reduces symptoms before we have loaded anything heavy.

The third is graded loading. Hinges, carries, anti-rotation and anti-extension work, built up progressively so the tissue tolerates more than the sport asks of it. Strength does belong in the answer. It is just rarely the opening move.

What a realistic timeline looks like

For a golfer with straightforward mechanical irritation and no red flags, meaningful change usually arrives inside four to eight weeks. Not always full resolution, but enough that eighteen holes stops being negotiated around the back.

Progress is rarely linear. A good week followed by a flare after a long round is normal and does not mean the plan is wrong. What matters is the trend across a month, which is another reason to write things down rather than rely on memory.

If eight weeks of sensible work produces nothing, that is information too. It usually means the driver is not what we assumed, and it is time to bring a clinician into the conversation rather than train harder.

Playing while you sort it out

Most golfers do not want to stop playing, and in most cases they do not have to.

Warm up properly — rotation before the first tee, not four practice swings. Consider walking rather than riding if the back is stiff rather than sharply painful; sitting in a buggy between shots is not the recovery people assume. Watch the practice-ground volume, which is often the real culprit rather than the round itself. And be honest about the days when the answer is nine holes, not eighteen.

If your back is limiting how you play or how much you practise, a screening will show which of those patterns is yours and what the load is doing. It is a more productive starting point than another set of core exercises from the internet.
