Returning to Core Exercise After Childbirth

Why your core deserves a gentle restart

Pregnancy stretches and reshapes your abdominal wall, your pelvic floor and the deep muscles that wrap around your spine. Birth — whether vaginal or by caesarean — adds its own layer of healing on top. That is why the old advice to "get back to sit-ups at six weeks" causes so much frustration. There is no universal timeline, only your body's own pace.

Your core is not just a set of abdominal muscles. It is a team: the diaphragm, the pelvic floor, the deep abdominal muscles and the muscles along your spine. Its day job is unglamorous but essential — helping you breathe, bend, lift a toddler, push a pram and carry shopping without leaking, aching or losing your balance. Rebuilding that team gently is the aim, not chasing a flat stomach.

Signs to slow down and seek advice

Some sensations are simply part of recovery and settle with time and graded activity. Others are a signal to stop and get a proper assessment. Book an appointment with a women's health physiotherapist if you notice any of the following:

• A feeling of heaviness, dragging or bulging in the vagina, especially towards the end of the day or after being on your feet.
• Leaking urine when you cough, sneeze, laugh, run or lift — this is common, but it is not something you have to live with.
• A visible doming, tenting or ridge running down the middle of your abdomen when you sit up or lift something.
• Pelvic, lower back, hip or tailbone pain that lingers or worsens with activity.
• Bleeding that becomes heavier or brighter after exercise, or a change in your lochia that tracks with activity.
• Pain during sex, or a sensation of something being "not quite right" internally.

Speak to your GP or health visitor too if you have significant pain, fever, or any concern about your caesarean scar. Getting assessed early is not a sign that something has gone wrong — it is simply good self-care.

Start with breath, not crunches

The most useful early exercise costs nothing and can be done lying on your side while your baby naps. It reconnects the diaphragm with the pelvic floor, which is the foundation everything else builds on.

The 360-degree breath: lie on your back with knees bent, or on your side with a pillow between your knees. Rest one hand on your lower ribs and the other on your belly. Breathe in through your nose, letting the ribs widen sideways and the belly soften and rise. Avoid forcing the belly out or gripping. Breathe out slowly through your mouth, and as you do, imagine gently lifting the pelvic floor — a subtle squeeze and lift, like stopping wind and urine at the same time, then drawing upwards.

Aim for five slow breaths, twice a day. Quality matters far more than quantity. If you cannot feel anything happening, that is normal in the early weeks; the connection returns with repetition.

Your first gentle movements

Once breathing feels comfortable, layer in small, controlled movements. Do these on a mat or a firm bed, and stop if you feel doming, heaviness or pain.

• Pelvic tilts: lying on your back, gently flatten the lower back towards the floor as you exhale, then release. Eight to ten slow repetitions.
• Heel slides: slide one heel away along the floor until the leg is straight, then draw it back. Keep the pelvis still and the abdomen soft.
• Glute bridges: with knees bent, peel the spine off the floor one vertebra at a time, pause, then roll down. Start with five.
• Side-lying clam: lying on your side with knees bent, lift the top knee a few centimetres without rolling the pelvis backwards.
• Four-point kneeling holds: on hands and knees, find a neutral spine and simply hold for three or four breaths before adding any leg or arm lifts.

Little and often beats long and exhausting. Two short sessions of five minutes will serve you better than one twenty-minute push.

Building strength for real life

Functional fitness after birth is about the movements you actually do all day. Every nappy change, car seat lift and trip up the stairs is a training rep, so use them well.

• Lifting your baby or the car seat: exhale as you lift, draw the ribs down, and keep the load close to your body. Avoid twisting while carrying.
• Pushing the pram: stand tall, soften the knees, and let your legs and glutes do the work rather than your lower back.
• Getting off the floor: roll onto your side, push up with your arms, and exhale as you rise.
• Carrying on one hip: swap sides regularly, and set the child down before you feel your back complain.

As you feel stronger, walking is the best next step. Build duration before speed, and only consider running once you can walk briskly, hop and cough without leaking, heaviness or pain.

Progress at your own pace

Recovery from birth is measured in months, not weeks, and it rarely follows a straight line. Sleep deprivation, feeding, and the sheer physical load of caring for a baby all affect how much you have to give on any given day. Rest days are part of the programme, not a failure of it.

Be kind to yourself, keep the movements small and consistent, and treat any worrying symptom as useful information rather than something to push through. A qualified women's health physiotherapist can assess your pelvic floor, check for abdominal separation and give you a plan tailored to your body — and that guidance is worth far more than any generic postnatal workout.
