Pregnancy Back Pain: Safe Exercises and Relief

The short answer

Back pain in pregnancy is one of the most common complaints I see, and the good news is that gentle, regular movement usually helps far more than rest. A simple daily routine of pelvic tilts, cat-cow, glute and pelvic floor activation, short walks and well-supported side-lying rest eases most aches within a couple of weeks. Warm (not hot) support and mindful posture do the rest. What you want to avoid is lying flat on your back for long periods in late pregnancy, deep twisting, and heavy lifting. If any of the warning signs I list at the end appear, please contact your obstetrician the same day rather than waiting to see whether they settle.

Why back pain happens in pregnancy

Several changes happen together, which is why the lower back and pelvis take the strain. As your baby grows, your centre of gravity shifts forward and the curve in your lower back deepens, so the muscles there work harder all day. A hormone called relaxin softens the ligaments around the pelvis to prepare for birth, which is helpful for delivery but leaves the joints a little looser and less stable. The deep tummy muscles stretch as your bump expands and can no longer hold the spine as firmly as before. Add tiredness, longer hours on your feet and broken sleep, and it is easy to see why the back protests. Some women feel the pain lower down, around the pubic bone or at the back of the pelvis, and find it sharp when turning in bed or climbing stairs; this pelvic girdle pain is related and responds to the same gentle, supported approach. This kind of pain is very common in the second and third trimester, and for most of my patients it settles steadily after delivery once the load and the hormones return to normal.

A safe routine you can start today

Work at a comfortable pace, breathe normally throughout, and stop any movement that causes pain, dizziness or breathlessness. None of these should ever feel like a strain. If you are unsure, or you have a higher-risk pregnancy, check with your doctor or physiotherapist first. Over an online consultation I can watch you move and tailor each of these to your stage and your symptoms.

1. Pelvic tilts

Why

They gently mobilise a stiff lower back and switch on the deep tummy and pelvic muscles that support your spine.

How

Stand with your back against a wall, or kneel on all fours. Softly draw your lower tummy in and flatten the small of your back, then release. Keep the movement small and smooth.

Dose

10 slow repetitions, two or three times a day.

2. Cat-cow

Why

This rocks the spine through a comfortable range, easing tension between the shoulder blades and in the lower back.

How

On hands and knees, wrists under shoulders and knees under hips, gently arch and then round your back in time with your breath. Move only as far as feels easy, never to the end of the range.

Dose

8 to 10 slow cycles, once or twice a day.

3. Glute activation in side-lying

Why

Strong buttock muscles take load off the lower back and steady the pelvis, which relaxin has left a little loose.

How

Lie on your side with knees bent and hips stacked. Keeping your feet together, open the top knee like a clam, then lower slowly. You should feel it working in the buttock, not the back.

Dose

10 to 12 on each side, once a day.

4. Pelvic floor work

Why

These muscles support your bladder, bowel and growing uterus, and training them helps both your back and your recovery after birth.

How

Sitting or standing, gently squeeze and lift as if stopping wind and the flow of urine at once. Hold for a few seconds, then fully relax. Do not hold your breath or clench your buttocks.

Dose

8 to 10 gentle holds, a few times a day.

5. Walking

Why

Easy, rhythmic movement keeps the joints supple, lifts your mood and helps you sleep, all of which reduce back pain.

How

Walk at a pace where you can still hold a conversation, on flat, even ground, in supportive shoes. Break it into short outings if one long walk feels like too much.

Dose

20 to 30 minutes on most days, as your energy allows.

6. Supported rest and warmth

Why

The right resting position takes pressure off the lower back and lets tired muscles recover.

How

Rest on your side, ideally the left, with a pillow between your knees and one supporting your bump. A warm (not hot) pack or a warm shower over the sore area for about ten minutes can soothe tight muscles. Avoid lying flat on your back for long stretches in late pregnancy.

Dose

Whenever you need it, and especially before bed.

Everyday habits that protect your back

How you move through an ordinary day matters as much as any exercise. When you stand, imagine a gentle line lifting you from the crown of your head, stack your ribs over your hips, and unlock your knees rather than bracing them. When you sit, choose a chair that supports your lower back, or tuck a small cushion behind it, and keep both feet flat on the floor with your hips a touch higher than your knees. Getting in and out of bed is a common flare point: roll onto your side first, then push up with your arms as you drop your legs over the edge, so you never sit straight up from lying. A well-fitted maternity support belt helps some of my patients through long days on their feet, and flat, cushioned shoes are far kinder to the back than heels or hard soles. Break up long periods at a desk or in the kitchen every half hour, even if only to stretch and walk to the next room.

Common mistakes I see

• Resting too much. Long spells of sitting or lying stiffen the back further. Gentle movement is usually the better medicine.
• Pushing into pain. More is not better here. Sharp or worsening pain is a signal to ease off, not to try harder.
• Deep twists and heavy lifting. With looser ligaments, big rotations and lifting toddlers or shopping can overload the pelvis. Bend your knees, keep loads close, and turn your feet rather than twisting your spine.
• Lying flat on the back in late pregnancy. This can press on a large vein and leave you faint, so favour side-lying and propped positions.
• Very hot packs or long hot baths. Use comfortably warm heat only, never hot, and keep it away from your tummy.
• Standing still for long periods. Shift your weight, take breaks and rest one foot on a low step to unload the back.

When to stop and seek help

Most pregnancy back pain is mechanical and settles with the care above. But certain symptoms are not routine and need prompt medical or obstetric attention. Stop exercising and contact your obstetrician, midwife or nearest maternity unit urgently if you notice any of the following:

• Any vaginal bleeding.
• Severe or constant abdominal pain.
• Regular tightenings or contractions, especially before your due date.
• Reduced or absent baby movements.
• Fluid leaking from the vagina, which may mean your waters have broken.
• Fever, chills or feeling generally unwell, or pain and burning when passing urine.
• A severe headache, changes to your vision, or sudden swelling of the face, hands or feet, which can signal pre-eclampsia.
• Pain, swelling, warmth or redness in one calf or leg, which can suggest a blood clot.
• Numbness, weakness or pins and needles in the legs, or any new difficulty controlling your bladder or bowels.

These red flags always come before any exercise plan. When in doubt, it is far safer to be checked and reassured than to wait at home and hope it passes.

The one-line summary

Keep moving gently, protect your back from twisting and heavy load, rest well supported on your side, and treat any warning sign as a reason to call your doctor the same day.
