Back in Motion: How an Exercise Physiologist Rehabilitates Lower Back Pain

Lower back pain is the most common reason people stop doing the things they love. Bending to pick up your kids. Sitting through a workday. Long runs, heavy lifts, a weekend round of golf.

The usual advice is rest, a handful of generic stretches, and a photocopied exercise sheet. It rarely works, because it treats every back the same. Your pain has its own triggers, your body has its own weak links, and you have your own reasons for wanting it fixed.

At In Between Performance, our exercise physiology clinic in Darlinghurst, Sydney, lower back rehab starts with finding out exactly what's going on. Then we build a program to fix it. Here's how we do it.

Why exercise works for lower back pain

Exercise is one of the best supported treatments for lower back pain we have. A major Cochrane review of exercise therapy for chronic lower back pain found it reduced pain by around 15 points on a 100-point scale compared with no treatment, usual care or placebo. The authors rated that a clinically important difference.

The reasons are practical. Stronger muscles around the spine, hips and legs share the load your back has been carrying alone. Better movement control spreads force more evenly. And moving through ranges you've been avoiding teaches your nervous system those movements are safe again, which turns down the pain response.

What matters is the right exercise, for the right person, at the right dose. That's why we don't start with exercises. We start with you.

Step 1: A brief history

A few targeted questions tell us most of what we need:

What aggravates it? Sitting, bending, lifting, running, getting out of bed.
What eases it? Movement, rest, heat, certain positions.
How and when it started. A sudden injury, a slow build, or something that comes and goes.
Where you feel it. Whether the pain stays in your back or travels into your buttock or leg, and any pins and needles or numbness.
What you want to get back to. Your goal shapes the whole program.
We also screen for the few warning signs that need a doctor first (more on those below).

Step 2: Functional assessment

Next, we look at how your body is set up and how it moves right now.

Postural observation. How you stand and sit, and how your pelvis, rib cage and head line up. This isn't about being "perfect". It's about spotting positions that keep loading the same sore spot.

Range of motion. How far you can bend forward, back, side to side and rotate, and where pain or stiffness kicks in. We check your hips too, because stiff hips often make the lower back do extra work.

Step 3: Strength testing with VALD

This is where we stop guessing. Using VALD dynamometry, we measure how much force the muscles around your back can produce, in numbers rather than "feels a bit weak".

Hip strength. Especially the glutes, which share load with your lower back every time you stand, walk, squat or lift.

Back strength. How well the muscles supporting your spine produce and hold force.

Left versus right. A gap between sides often shows up as one sided pain or a movement that drifts.

The results show exactly where there's room to build strength, and because they're measured, we can re-test as you progress. You'll see your numbers climb, not just feel better.

Step 4: Additional strength and capacity tests

VALD tells us how strong a muscle is. Capacity tests tell us how long and how well you can use that strength. Depending on your goals, these can include:

Core capacity. How long you can hold your trunk steady.

Single leg stance capacity. How well you balance and control your pelvis on one leg, the base of walking, running and stairs.

Leg strength capacity. How your legs handle repeated work, so your back isn't picking up the slack.

Step 5: Movement patterns and stacking the spine

In the first few sessions, this is usually the most important piece. Good movement patterns are the foundation the rest of your rehab is built on.

The key is stacking the spine:

Pelvis in a neutral, controlled position
Rib cage sitting over the pelvis, not flared or collapsed
Head in line on top

When these are stacked, load moves through your body the way it's meant to, instead of piling excess stress onto your lower back. Once you can hold that position, it carries into every exercise we use to build your capacity, from squats and hinges to carries and single- leg work.

Step 6: Building your program

Now we build. Everything we've learned, from your aggravating factors to your strength numbers to how you stack your spine, feeds directly into your program.

1. Settle and set the foundation. Early sessions calm things down and lock in good stacking and movement patterns in pain-tolerable ranges.

2. Build strength where it's missing. Targeted work for the weak links we measured, whether that's hips, trunk or one side more than the other.

3. Load it up. Progressive loading so your back becomes robust, not just pain-free. This is where most generic programs stop too early.

4. Return to what you love. The final phase looks like your goal: lifting, running, sport or simply a pain-free workday.

We re-test along the way, so your program keeps evolving as you get stronger.

When to see a doctor first

Most lower back pain isn't caused by anything serious, and it responds well to exercise. A small number of symptoms need medical attention before rehab starts.

Go to an emergency department straight away if you have back pain with any of these:

Back in Motion: Lower Back Rehab

Numbness around your groin, buttocks or inner thighs New trouble controlling your bladder or bowels Weakness in your legs that's getting worse

See your GP promptly if your back pain comes with:

Unexplained weight loss, fever or feeling generally unwell
A history of cancer
Pain after a significant fall or accident
Severe pain at night that doesn't ease with rest or changing position

If any of these come up during your assessment, we'll refer you on before we start training.

Lower back rehab with an exercise physiologist in Darlinghurst

An Accredited Exercise Physiologist (AEP) is a university-qualified allied health professional who prescribes exercise to treat injuries and chronic conditions. Lower back pain is one of the most common things we treat, from office workers with stiff, sore backs to athletes trying to get back to training.

Our clinic is in Darlinghurst, an easy trip from Surry Hills, Paddington, Potts Point, Woolloomooloo and the Sydney CBD. If getting in is hard, we also run online sessions and mobile visits across Sydney.

Lower back pain FAQs

Should I rest or exercise with lower back pain?

For most back pain, staying active beats bed rest. You may need to modify what you do for a while, but gentle movement usually helps recovery. A structured program speeds it up.

What are the best exercises for lower back pain?

There's no single best exercise for everyone. The best program targets your specific weak links and movement patterns, which is why we assess before we prescribe.

How long does lower back rehab take?

Many people notice improvement within a few weeks. Building lasting strength and returning fully to sport or heavy lifting usually takes a few months, depending on how long the pain has been there.

Do I need a scan before starting?

Usually not. Most lower back pain doesn't need imaging, and scan findings often don't match symptoms. If your assessment shows a scan is needed, we'll refer you to your GP.

Lower back pain is common, but staying stuck with it isn't inevitable. Exercise is one of the best-supported treatments we have. The catch is that generic exercise only goes so far. Results come from the right exercise, for your back, progressed at the right pace.

That's why our process runs in the order it does. A short history tells us what flares your pain and what settles it. The functional assessment shows how you're set up and how you move. VALD and capacity testing turn "feels weak" into numbers we can track and improve. Movement patterns tie it all together.

In our experience, that last piece matters most early on. Learning to stack your pelvis, rib cage and head well is the foundation everything else is built on. Get it right in the first few sessions, and every exercise that follows loads your body the way it's meant to be loaded, rather than piling stress onto a sore spot. Get it wrong, and even a good program ends up reinforcing the same old pattern.

Pain-free is the first goal, not the last. The aim is a back that's strong enough for whatever you want from it, whether that's a heavy deadlift, a long run, a full day at the desk or picking up your kids without thinking twice. That space between where you are now and where you want to be is the in between. It's where we do our best work.

If lower back pain is holding you back, book an assessment at our Darlinghurst clinic, or ask about online sessions and mobile visits across Sydney.
