The Best Exercises for Back Pain and Sciatica

Sutton & South London Physio Guide

Written by Jai Mistry, Co-Director & Specialist Physiotherapist | London Sports Physio, Sutton

If you’re dealing with back pain or sciatica, chances are you’ve searched for the “best exercises” to fix it. You may have been told to strengthen your core, stretch your hamstrings, try nerve glides, or avoid certain movements altogether.

But when we look at the research (and what we see every day in clinic at London Sports Physio) a very different picture emerges.

There isn’t one perfect exercise. There isn’t a universal routine that works for everyone. And recovery is not about finding the “correct” movement.

It’s about returning to movement in general.

This article was written by Jai Mistry, Co-Director of London Sports Physio, who is currently undertaking a PhD focused on back pain and sciatica research.

If you want to understand how we approach this clinically, you can also read our dedicated guide on our back pain treatment page, which explains how we assess and treat back pain at our Sutton clinic.

The Biggest Misconception: There Is No “Perfect” Exercise

Research consistently shows that different types of exercise produce similar outcomes for back pain and sciatica.

This includes:

Strength training
Stretching
Walking
Yoga or Pilates
General physical activity

All of these can help but none consistently outperform the others across all patients.

That challenges the idea that you need a highly specific corrective exercise programme.

Instead, the evidence supports something much simpler:

The best exercise is the one that helps you move regularly and consistently.

This is also the foundation of how we approach rehabilitation at our back pain clinic in Sutton, which you can read more about on our back pain page.

It’s Not About Having a “Strong Core”

One of the most common beliefs in back pain is that the problem is caused by a weak core.

But if that were true, we would expect:

People with strong cores to never get back pain
Core training to eliminate back pain entirely

That clearly isn’t the case.

We see elite athletes with exceptional core strength still experience back pain. We also see many people with average strength who never develop symptoms.

Core exercises can help but not because they are magical or essential.

They help because they:

Encourage movement
Apply load to the body
Improve tolerance to stress

If a strong core alone prevented back pain, everyone would have a six-pack and back pain wouldn’t exist.

It’s far more complex than that.

This is something we explain in more detail on our back pain treatment page, where we break down how pain actually develops and why exercise is only one part of recovery.

Everyone Is Different: There Is No One-Size-Fits-All Approach

Back pain and sciatica are highly individual.

Two people can have identical scans or symptoms but respond completely differently to the same movement.

For example:

One person feels better bending forward
Another feels worse with the same movement
One tolerates lifting easily
Another finds it aggravating at first

Even pain itself varies:

What feels painful for one person may feel fine for another
What helps one person may not help someone else

This is why generic exercise sheets often fail.

At London Sports Physio, we assess each person individually rather than applying a one-size-fits-all programme.

Instead of asking:

“What exercise should I do?”

A better question is:

“What can I do that feels manageable and helps me stay active?”

You can learn more about this personalised approach on our back pain page.

Is It Safe to Move With Pain?

This is one of the biggest concerns people have.

Pain feels like a warning signal, so it’s natural to assume movement might be harmful.

But modern pain science shows something important:

Pain does not always equal damage.

In many cases of back pain and sciatica, pain is more related to sensitivity than injury.

That means:

You can feel pain without causing harm
Movement is generally safe
Avoiding movement completely can actually slow recovery

So yes:

It is usually safe to move with some level of pain.

This is a key principle we use in rehab at our Sutton clinic, and it’s explained further on our back pain treatment page.

Why Movement Helps: Reducing Sensitivity

When pain persists, the nervous system can become more sensitive:

Movements feel more threatening
Load feels heavier than it should
The body becomes protective

This is often referred to as central sensitisation.

Avoiding movement can reinforce this cycle:
Less movement → less tolerance → more sensitivity → more pain

Movement helps reverse it.

Through gradual exposure, you:

Reduce sensitivity
Improve tolerance to load
Rebuild confidence in movement

This is a key principle behind graded exposure, which we use clinically at London Sports Physio and explain on our back pain page.

Movement Improves Circulation and Tissue Health

Exercise also helps physically by:

Improving blood flow
Supporting tissue health
Reducing stiffness
Maintaining joint mobility

Even simple walking can:

Improve circulation around the spine
Help reduce stiffness
Support recovery

This is why prolonged rest is no longer recommended for most back pain or sciatica cases.

The Role of Load and Tension

Your body is designed to handle load, bending, lifting, twisting, and carrying are normal everyday movements.

But when pain develops, people often avoid these completely.

Over time this leads to:

Reduced strength
Reduced tolerance to load
Increased fear of movement

Exercise helps reintroduce load gradually.

This builds:

Resilience
Confidence
Long-term capacity

We explore this in more detail on our back pain treatment page, where we explain how we progressively rebuild load tolerance in clinic.

What About Sciatica?

Sciatica often involves:

Pain down the leg
Tingling or numbness
Sharp or shooting symptoms

Despite how it feels, the overall approach is similar.

Most cases improve with:

Time
Movement
Gradual return to activity

Research shows that around 80% of cases improve within six months with conservative management.

No single exercise has been shown to be superior.

What matters most is:

Staying active
Finding tolerable movement
Progressing gradually

So What Should You Actually Do?

Rather than focusing on a rigid exercise list, focus on principles:

1. Move regularly

Walking, light activity, and general movement are key.

2. Start where you are

Begin with what feels manageable and build gradually.

3. Use pain as a guide, not a barrier

Mild discomfort is often okay. Severe or worsening pain means adjust.

4. Progress over time

Increase movement, load, and confidence gradually.

5. Choose what you enjoy

Consistency matters more than exercise type.

Common Mistakes to Avoid

Searching endlessly for the “perfect” exercise
Bracing and voiding movement completely
Assuming pain always means damage
Comparing your recovery to others

These often slow progress rather than improve it.

The Bigger Picture

Back pain and sciatica are influenced by:

Movement habits
Nervous system sensitivity
Stress and lifestyle
Physical load capacity

That’s why simple, rigid solutions rarely work.

At London Sports Physio, we focus on restoring movement confidence, not chasing perfect exercises.

Final Thoughts

The research is clear:

The best exercise for back pain and sciatica is the one that helps you move more, more often.

You are not fragile. Your back is strong and designed to move.

Pain does not automatically mean damage.

With the right guidance, movement can:

Reduce sensitivity
Improve circulation
Increase load tolerance
Rebuild confidence

Everyone is different. What works for one person may not work for another.

That’s why we don’t use one-size-fits-all programmes.

Instead, we tailor rehabilitation to the individual at our Sutton clinic—and explain this approach in detail on our back pain treatment page.
