Scoliosis Exercises and Sciatica Exercises
The short answer
Scoliosis is a sideways curve of the spine.
- Sciatica is pain from an irritated or squeezed sciatic nerve.
- For scoliosis, the NHS says back exercises are unlikely to change the curve but may ease pain, and general exercise should not be avoided unless your doctor advises it.
- For sciatica, the NHS says keep up normal activities and start gentle movement early.
- A coach works inside your physio's plan and does not diagnose or treat either.

Looking for scoliosis exercises or sciatica exercises?
They are two different conditions, so this page treats them in separate sections. It is for adults a doctor or physio has already assessed, who now want to strength train. It is general information, not medical advice.

Key facts
- Scoliosis most often starts between ages 10 and 15, and about 8 in 10 cases have no known cause (NHS)
- In Singapore, Primary 5 and 6 girls are screened for scoliosis at school with the Forward Bending Test (HealthHub)
- A 2024 Cochrane review of 13 trials in 583 adolescents found the evidence on exercise and curve size very uncertain
- Sciatica usually gets better in a few weeks to a few months, but it can come back (NHS)
Are scoliosis and sciatica the same thing?
No. Scoliosis is about the shape of the spine. Sciatica is about a nerve. You can have one, both or neither, so read the section that matches what your doctor told you.
| Scoliosis | Sciatica | |
|---|---|---|
| What it is | The spine twists and curves to the side | The sciatic nerve is pressed or irritated |
| Main symptom in adults | Back pain, uneven shoulders or hips | Pain down the back of one leg, sometimes with tingling or numbness |
| Usual course | Tends to stay the same once growth stops | Usually better in weeks to a few months |
| What exercise aims at | Easing pain and staying strong, not changing the curve | Staying active while the nerve settles |
What is scoliosis?
Scoliosis is when the spine twists and curves to the side, says the NHS. It is usually not a sign of anything serious, and mild scoliosis does not always need treatment.
- Ages 10 to 15When it startsMost often in children of this age, though it can affect any age. Signs are a visibly curved spine, leaning to one side, uneven shoulders or hips, or ribs sticking out on one side.
- After growthCurve holdsThe curve tends to stay the same. See a doctor if it gets worse.
- In adultsBack painBack pain is more common. Some adult scoliosis comes from age-related wear and tear.
The cause is unknown in about 8 in 10 cases. The NHS says it is not linked to posture, exercise or diet.
How is scoliosis picked up in Singapore?
Usually at school. HealthHub says Primary 5 and 6 girls are screened, because scoliosis is more common in girls at that age.
- 01Forward Bending TestA female doctor or nurse checks the back in private as the student bends forward (HealthHub).
- 02ReferralA child who needs more checks is referred to the Health Promotion Board's Student Health Centre (HealthHub).
- 03X-rayThe NHS says an X-ray is used to measure the curve.
- 04See a doctor firstIf you were never followed up, or the curve was never measured, see a doctor before you start training.
Do scoliosis exercises straighten the spine?
The evidence does not show that they do. Be wary of anyone who promises a straighter spine from exercise. Here is what the sources we read say:
| Source | What it says |
|---|---|
| NHS scoliosis overview | It is not clear whether back exercises help improve scoliosis. General exercise is good for overall health and should not be avoided unless your doctor advises it. |
| NHS treatment in adults | Exercises taught by a physiotherapist are unlikely to change the curve but may reduce pain. Strengthening and stretching the back may ease pain. |
| Cochrane review, 2024 | 13 trials, 583 adolescents. Compared with no treatment, the evidence on exercise and curve size is very uncertain. Scoliosis-specific exercises with a brace may slightly reduce the curve, at low certainty. The authors call the evidence limited. |
The Cochrane review studied teenagers who were still growing. We did not find comparable trials in adults. For adults, the realistic aims are less pain and more strength.
How should adults with scoliosis strength train?
Like anyone else, within any limits your doctor sets. The NHS says most people with scoliosis can do most activities, including exercise and sport. It says exercise should not be avoided unless your doctor advises it.
- 01Ask your doctor firstWhether any movements or loads are off limits, especially after spinal surgery.
- 02Train the whole bodyLegs, hips, back and trunk, with loads that build slowly.
- 03Work each sideSingle-arm and single-leg moves let a coach see if one side tires or hurts sooner, and note it for your physio.
- 04Track pain, not postureA coach logs how your back feels the next day. A coach does not try to change the curve.

What is sciatica?
Sciatica is pain that happens when something presses or rubs on the sciatic nerve, which runs from the lower back to the feet, says the NHS. The most common cause is a slipped disc.
- 01Nerve pressedMost often by a slipped disc. Other causes are narrowing of the spinal canal (spinal stenosis), a spinal bone slipping out of place (spondylolisthesis) or a back injury.
- 02Leg painSharp or burning pain in the buttock and down the back of one leg, sometimes with tingling, numbness or weakness.
- 03Worse with movementMoving, sneezing or coughing can make it worse.
- 04SettlesUsually in a few weeks to a few months. It can come back.
Doctors in Singapore are seeing it in younger adults too. In a Straits Times article republished by Singapore General Hospital, an SGH orthopaedic surgeon said 80% of patients respond to non-surgical care such as physiotherapy, activity changes and pain medicine, and most cases settle in three to six months.
When is sciatica an emergency?
Go to A&E or call 995 if you have any of these. The NHS says they can be signs of a serious back problem that needs hospital treatment as soon as possible. Do not drive yourself.
Go to A&E or call 995
- Both legs: sciatica on both sides, or severe or worsening weakness or numbness in both legs.
- Saddle numbness: numbness around the genitals or bottom.
- Bladder changes: difficulty starting to pee, being unable to pee or losing control, when this is not normal for you.
- Bowel changes: not noticing the need to poo, or losing control of your bowels.
See your doctor soon, not a coach
- The pain has not improved after a few weeks (NHS).
- The pain is getting worse (NHS).
- The pain stops your normal activities (NHS).
What exercises help sciatica?
Moving helps more than resting. The NHS advises keeping up normal activities as much as you can, starting gentle movement early and not sitting or lying down for long periods. It says moving is not harmful, even when it hurts.
- 01Gentle movement firstShort walks and the gentle exercises your physio gives you. The NHS sciatica exercise video is a starting point, and it says to stop any exercise that causes pain.
- 02Break up sittingStand and walk between long sitting blocks at work and on the commute.
- 03Build strength once clearedHips, legs and trunk, with light loads and more reps, added a little at a time.
- 04Return to normal trainingHeavier lifts come back last, when your physio agrees and the leg pain has settled.
If your sciatica comes from a disc, our slipped disc guide sets out a 12-week plan with sets and reps. For back pain without leg symptoms, see training with back pain.
What should you be careful with when training with sciatica?
Anything that spreads pain further down the leg. That is a coach's cue to stop the exercise and tell your physio.
- 01Heavy lifting with poor formA neurosurgeon in the SGH article said they see many people who deadlift come to the clinic with back pain that shoots down their legs.
- 02Long static positionsA pain specialist quoted in the same article warned that after long hours at a workstation the supporting back and core muscles gradually weaken.
- 03Pushing through new symptomsNew numbness, pins and needles or a weak leg end the session.
How does a coach train around scoliosis or sciatica at home or in a condo gym?
Inside your physio's plan, with you carrying notes between them. The physio assesses and treats. The coach adds coached strength sessions and reports back through you.
| Task | Doctor or physio | Coach |
|---|---|---|
| Diagnose and measure a curve or nerve problem | Yes | No |
| Treat pain or rehabilitate | Yes | No |
| Set limits and clear exercises | Yes | No |
| Coach cleared exercises and build load slowly | Sometimes | Yes |
| Log loads and next-day symptoms for your physio | Reads the log | Yes |
- 01At homeFloor work, bands, dumbbells and walking. No commute and no long car ride first.
- 02Condo gymA cable stack, dumbbells and a bench cover most of a strength plan.
- 03Before the first sessionSend the coach your diagnosis, physio notes and any limits. How coaching fits with physio is on physio or personal trainer.
How do you start with a Fit Titans coach?
Message us with your diagnosis, what your doctor or physio has cleared, and your goal. A coach comes to your home, your condo gym, a park or a gym that allows outside trainers.
The first session is a paid trial at 10% off the coach's rate. After it, sessions come in packs of 5, 10, 15 or 20, paid by PayNow. See injury rehab coaching for how we work alongside a physio.
Questions about scoliosis and sciatica
Can exercise fix scoliosis?
The NHS says it is not clear whether back exercises help improve scoliosis, and that physio exercises are unlikely to change the curve in adults but may reduce pain. A 2024 Cochrane review in adolescents rated the evidence on curve size as very uncertain. Exercise is still good for overall health.
Can I lift weights with scoliosis?
Most people with scoliosis can exercise and play sport, says the NHS. Check with your doctor first, especially after spinal surgery, and build load slowly with a coach who follows any limits your doctor sets.
Should I rest when I have sciatica?
The NHS advises against sitting or lying down for long periods. Keep up normal activities as much as you can and start gentle movement early. Moving is not harmful, even if it hurts.
How long does sciatica last?
The NHS says it usually gets better in a few weeks to a few months, and it can come back. An SGH surgeon said most cases settle in three to six months. See a doctor if it is not improving after a few weeks or is getting worse.
Can a personal trainer treat my sciatica or scoliosis?
No. A doctor or physio diagnoses and treats. A coach delivers the strength work they have cleared, between physio visits, and reports back through you.
