Best Exercises for Sciatica - Physio-Approved Guide

Quick answer: Most sciatica responds well to a structured exercise plan that combines nerve mobilisation drills (slump slider, sciatic nerve flossing), directional preference work (usually McKenzie press-ups if the back prefers extension), and core and glute strengthening. Start gentle and err on the side of caution; exercises should reduce leg symptoms or keep them the same - not make the leg symptoms worse or spread further down. If leg symptoms worsen or you develop weakness, numbness in the saddle area, or bladder/bowel changes, see a doctor immediately.

What Sciatica Actually Is

Sciatica describes pain, tingling, numbness, or weakness travelling down the leg from the lower back - usually caused by irritation of the sciatic nerve or one of its lumbar spinal roots (most commonly L5 or S1). Common drivers:

• Disc bulge or herniation pressing on a nerve root
• Lumbar spinal stenosis - canal narrowing, usually in older adults
• Piriformis syndrome - a deep hip muscle irritating the nerve
• Facet joint irritation referring pain down the leg

Exercise selection depends on the underlying cause and - most usefully - which direction of movement relieves your leg symptoms.

The Golden Rule - Centralisation

A key sign that an exercise is helping: leg symptoms pull back toward the back (centralise). A sign an exercise is not helping: leg symptoms spread further down or get more intense.

• Back pain worsening but leg symptoms centralising = usually good progress
• Leg symptoms worsening even if back pain improves = usually a bad sign

Use this to test which exercises suit your specific case.

Before You Start

• Avoid prolonged sitting - change position every 20-30 minutes
• Avoid heavy lifting during flares
• Mild increase in back pain during exercise is OK if leg symptoms stay same or improve
• Sharp leg pain worsening, or new weakness/numbness = stop, assess
• If in doubt, start with nerve glides and gentle mobility

Phase 1 - Symptom Management (Daily, 10-15 Minutes)

1. McKenzie Press-Ups (Prone Extension)

Lie face-down on the floor. Press the upper body up on forearms or hands, letting the hips sag. Breathe. Hold 5-10 seconds, lower. 10 reps, 3-5× daily.

Crucial: this helps most disc-related sciatica where leg symptoms centralise with extension. If leg symptoms worsen or push further down, stop and try flexion exercises instead.

2. Sciatic Nerve Glides (Sliders)

Sit tall on a chair. Extend the painful leg straight while tilting the head back (look up). Then bend the knee while bringing the chin to the chest. Move slowly. 10 reps, 2-3× daily. Mobilises the nerve without over-stretching.

3. Piriformis Stretch (Figure-4)

Lying on back, cross the painful-side ankle over the opposite knee. Gently pull the uncrossed leg toward your chest. Hold 30 seconds each side.

4. Knee to Chest

Lying on back. Bring one knee toward the chest, hold 15 seconds. 3 reps each side. Good for stenosis-type sciatica or when flexion feels better.

5. Pelvic Tilts

Lying on back, knees bent. Flatten the low back into the floor (posterior tilt), then allow a small arch (anterior tilt). 10 reps. Gentle mobility.

Phase 2 - Strengthening (Weeks 2-6, 3-4× Week)

Add once Phase 1 is well tolerated.

1. Glute Bridge

Lying on back, knees bent. Squeeze glutes and lift hips. 3 sets of 12. Progress to single-leg version.

2. Bird-Dog

On hands and knees. Extend opposite arm and leg. Hold 5 seconds. 3 sets of 8 each side. Core and stabiliser drill.

3. Dead Bug

Lying on back, arms up, knees bent 90°. Lower opposite arm and leg slowly. 3 sets of 10. Deep core without spinal loading.

4. Clamshells

Side-lying with knees bent. Lift the top knee. 3 sets of 15 each side.

5. Side Plank (knee or full)

Hold 15-30 seconds each side. Trains lateral core.

6. Wall Sit

Against a wall, 45° knee bend. Hold 20-45 seconds. Quads and posterior chain.

Phase 3 - Return to Function (Weeks 6+)

• Hip hinges with light dumbbell - foundation for safe lifting
• Goblet squats
• Walking progression - 30-45 minutes at conversation pace
• Romanian deadlifts (light, with good form)
• Farmer's carries

Directional Preference Summary

• Leg symptoms improve with extension (lying on tummy, propping on elbows): emphasise McKenzie press-ups, standing back-bends, sleeping on back or side
• Leg symptoms improve with flexion (sitting, curling forward, pushing trolley): emphasise knee-to-chest, child's pose, posterior pelvic tilts

A physiotherapist identifies your directional preference in 10-15 minutes and builds the plan around it.

Piriformis-Type Sciatica Focus

If the problem is piriformis irritating the nerve (often triggered by prolonged sitting or a Kembara-style cross-country drive):

• Figure-4 stretch
• Deep glute stretch (lying with ankle on opposite knee, knee pulled to chest)
• Gluteus medius strengthening (clamshells, band walks)
• Avoid prolonged cross-legged sitting

Exercises to Avoid During a Flare

• Full sit-ups or crunches
• Deep forward folds ("toe touches") if flexion aggravates
• Heavy barbell squats and deadlifts
• Aggressive hamstring stretching that reproduces leg symptoms
• Twisting exercises (seated twists, Russian twists) with leg symptoms active

Red Flags - Seek Urgent Medical Care

• Loss of bladder or bowel control
• Numbness in the saddle (inner thighs, groin)
• Progressive leg weakness, foot drop
• Severe, unrelenting pain not responding to any position
• Fever, unexplained weight loss, history of cancer

Cauda equina syndrome is a surgical emergency. Don't wait.

When to See a Physiotherapist

• Leg symptoms lasting more than a week
• Symptoms affecting sleep or work
• Unsure which direction of movement helps
• Numbness or mild weakness (not red-flag pattern)
• Recurring episodes

Frequently Asked Questions

Should I rest or exercise for sciatica? Gentle movement beats bed rest. 1-2 days of relative rest is fine for severe flares; beyond that, movement speeds recovery.

How long does sciatica take to resolve? Around 60-70% improve significantly within 6-8 weeks with structured exercise. Some cases take 3-6 months. A small minority need surgical consultation.

Do I need an MRI for sciatica? Usually no in the first 6 weeks. MRI is indicated if there's red-flag symptoms, severe weakness, or if symptoms haven't improved after structured rehab.

Can I still walk? Usually yes. Walking often helps sciatica. Start with short walks and build. If walking worsens leg symptoms significantly, try gentle cycling or swimming instead.

Is yoga good for sciatica? Some postures help (cobra for extension-responsive sciatica, child's pose for flexion-responsive). Deep pigeon pose, seated forward folds, and extreme hip-opening poses often aggravate sciatica. Take gentle classes and stop any pose that worsens leg symptoms.

Should I use a back brace? Usually no for exercise. Short-term use during flares is fine. Long-term reliance reduces natural core activation.

Can I work out at the gym? Yes, with modifications - upper body, core stability (bird-dog, dead bug), and machines that keep the spine neutral. Avoid heavy barbell squats and deadlifts during flares.

How do I prevent sciatica coming back? Maintain a consistent core and glute strengthening routine, keep moving throughout the day, practise safe lifting technique, and address any deconditioning that's crept in.

Move Smart, Centralise Symptoms, Rebuild Resilience

Most sciatica resolves with a structured exercise plan that respects your body's directional preference and progressively rebuilds core, hip, and movement control.
