Short answer: The best sciatica exercises are gentle, specific movements — nerve glides, the prone press-up, the knee-to-chest stretch, the piriformis stretch, and gradual core and hip strengthening — done in the direction that eases your leg pain. The wrong exercises, or the right ones done too aggressively, can flare it up, so match them to your pattern.
If you have pain shooting from your lower back down your leg, you are probably searching for exercises that help. The honest answer is that the right movement, matched to your specific pattern, is one of the most effective treatments for sciatica — but the wrong movement can make it worse. Here is how to think about it, and the exercises physiotherapists most often use.
Why exercise helps sciatica
Sciatica usually comes from an irritated nerve in the lower back. Gentle, specific movement helps the nerve glide, keeps the spine mobile, and reduces the sensitivity that keeps pain switched on. Complete rest, by contrast, tends to stiffen the back and prolong recovery. Staying gently active is one of the most evidence-based things you can do.
The one principle that matters most: centralisation
The most useful idea in sciatica rehab is centralisation: movements that pull the pain out of your leg and back towards your spine are usually good, while movements that push pain further down the leg are usually ones to ease off. This is why a personalised assessment matters — the “right” direction is different from person to person. As you do the exercises below, use this rule: less leg pain is good; more leg pain means stop and adjust.
5 gentle sciatica exercises to try
Do these slowly, within comfort. Stop any that increase the pain travelling down your leg.
1. Nerve glides (sciatic nerve flossing)
Sitting tall, slowly straighten one knee to lift the foot while tipping your head back slightly, then lower the foot as you drop your chin. It should feel like a gentle “floss,” not a stretch into pain. 10 slow repetitions. This helps the irritated nerve move freely again.
2. Prone press-up (extension)
Lie on your front and, keeping your hips on the floor, gently prop up onto your forearms or hands, letting your lower back relax into a mild arch. Hold a few seconds and lower. For many people this “centralises” leg pain back towards the spine. 8–10 repetitions.
3. Knee-to-chest stretch
Lying on your back, gently draw one knee towards your chest and hold for 20–30 seconds, then swap. Eases tension in the lower back and buttock. Skip it if it worsens leg symptoms.
4. Piriformis (buttock) stretch
Lying on your back, cross the affected ankle over the opposite thigh and gently pull the uncrossed thigh towards you. You should feel a stretch deep in the buttock. Hold 20–30 seconds. Helpful when a tight buttock muscle is irritating the nerve.
5. Gentle walking
Short, frequent walks keep the nerve moving and the back mobile. Build up little and often, within comfort — this is one of the most underrated “exercises” for sciatica.
Building strength (once the pain is settling)
As symptoms calm down, gradually add strengthening — this is what prevents sciatica coming back:
- Core activation (gentle abdominal bracing, then progressions)
- Glute bridges for the hip and buttock muscles
- Hip and back strengthening, introduced progressively
Strength should be built up gradually and painlessly — a physiotherapist will progress these at the right pace for you.
What to avoid early on
- Repeated deep forward bending, especially first thing in the morning
- Heavy lifting or prolonged sitting
- Aggressive hamstring or leg stretching through sharp nerve pain
- Pushing any exercise that sends more pain down the leg
How long until sciatica exercises work?
Many people notice a change within a couple of weeks of doing the right exercises consistently. More stubborn cases take longer and benefit from a structured, progressive plan. If you are doing “sciatica exercises off the internet” and not improving, it usually means the exercises are not matched to your specific pattern — which is exactly what an assessment fixes.
When to get assessed (and red flags)
Get assessed promptly if your leg pain is severe, spreading, or not improving after a couple of weeks. Seek urgent medical care if you develop numbness around the groin or inner thighs, difficulty controlling your bladder or bowels, or rapidly worsening leg weakness — these are rare but need immediate attention.
A home physiotherapy visit can identify your specific pattern and give you a plan that matches it, rather than generic exercises. Sciatica is part of the wider picture of back pain, and treating the cause is what keeps it from returning.
