Diastasis Recti & Core Recovery

During pregnancy, your abdominal wall stretches and adapts to make room for your growing baby. The two long rectus abdominis muscles at the front of the abdomen move further apart as the connective tissue between them - the linea alba - widens. This is commonly called diastasis recti, abdominal separation or divarication. It is an adaptation to pregnancy, not evidence that your body is broken.

Seeing or feeling a gap after birth can be worrying, but early postnatal separation is common. Recovery is not simply about making a gap disappear. Your ability to breathe, move, manage pressure, develop abdominal strength, coordinate with your pelvic floor and return comfortably to everyday activity are all important parts of the picture.

Why does abdominal separation happen?

As the uterus grows during pregnancy, the abdominal wall lengthens and the linea alba widens to accommodate the changing shape of the abdomen. After birth, the tissues need time to recover and adapt again.

For many people the separation changes naturally during the postnatal months. Others continue to notice a gap, softness through the middle of the abdomen, a ridge or "doming" during certain movements, or a feeling that their core is not supporting them as it used to. These observations can guide rehabilitation without defining whether your recovery is successful.

A gap is only part of the story

It can be tempting to judge recovery by how many fingers fit between the abdominal muscles. Gap width can be useful information in an assessment, but it does not tell the whole story.

Core recovery is also about how well the abdominal wall can create and manage tension, how comfortably you can move and breathe, whether the abdomen bulges or domes during effort, how the pelvic floor responds, and whether symptoms such as pain, heaviness or leakage are present.

The aim of this Hub is not to encourage repeated measuring or make you feel that your abdomen needs to look a particular way. We want to help you understand function, build confidence and recognise the support options that may help you progress.

What is doming or coning?

You may notice a ridge or bulge appearing along the centre of your abdomen when you sit up, lift, exercise or perform another effortful movement. This is often described as doming or coning.

Doming can be a useful sign that a particular movement or load is currently challenging your pressure management. It does not automatically mean that the movement is harmful. Rather than fearing movement, try making the task easier - for example by reducing the load or range, slowing down, changing position or breathing through the effort - then build back up as control and confidence improve.

If doming is persistent, uncomfortable or difficult to manage, or you feel unsure about progressing, individual pelvic-health guidance can be useful. The aim is to understand how your abdominal wall, breathing, movement and pelvic floor are working together rather than simply measuring a gap.

Your core is more than your abdominal muscles

Core function involves a coordinated system rather than one muscle working in isolation. Your diaphragm, abdominal wall, pelvic floor and surrounding muscles respond together as you breathe, move, lift and manage pressure.

This is why postnatal core recovery fits naturally alongside pelvic health. Simply pulling your stomach in harder or repeatedly performing abdominal exercises is not the whole answer.

Breathing can be a useful place to begin

Gentle breathing awareness can help you reconnect with the abdominal wall and pelvic floor. In a comfortable position, allow the ribs and abdomen to expand naturally as you breathe in. As you breathe out, you can explore a gentle abdominal and pelvic-floor response without forcing or holding your breath.

The goal is not a maximum contraction. It is to begin restoring awareness and coordination that can later be carried into everyday movements such as rolling, standing, lifting your baby, pushing a pram and returning to exercise.

Gradually rebuilding strength

Postnatal abdominal rehabilitation can progress from reconnection into meaningful strength. Current research supports exercise as an important conservative approach, although studies use different programmes and do not identify one universally superior routine. Gentle deep-abdominal work can be a useful starting point for some women, but recovery should progress towards using both deeper and more superficial abdominal muscles in the movements and activities that matter to you.

As you become more comfortable, this may progress from supported positions into sitting, standing and functional movements, and eventually into more challenging strength or impact exercise where appropriate.

There is no single exercise that "fixes" diastasis for everybody, and the research does not support promising that a particular routine will permanently "close the gap". Exercise may improve strength, control, function and, in some studies, inter-recti distance. The right progression depends on your recovery, symptoms, birth experience, current strength and goals.

Do I have to avoid sit-ups and planks forever?

No. Sit-ups, curl-ups, planks and other abdominal exercises are not automatically forbidden for life. Early in recovery, some movements may create more pressure or doming than you can comfortably manage, so a gentler starting point can be appropriate. As strength and pressure management improve, more challenging abdominal work can often be reintroduced progressively where appropriate.

Think progression rather than prohibition. Build control and strength first, then gradually increase challenge. If an exercise consistently causes uncontrolled doming, pain, pelvic heaviness or leakage, modify it and seek guidance if needed.

Everyday pressure matters too

Core recovery happens outside exercise sessions as well. Repeated straining with constipation, holding your breath during lifting, or repeatedly choosing tasks that are currently too demanding can all increase pressure through the abdominal wall and pelvic floor.

Simple strategies can help: breathe through effort, keep loads close to your body, use your legs when lifting, roll onto your side to get out of bed in the early stages, and address constipation rather than repeatedly straining. If bowel emptying is difficult, a low footstool can help by bringing the knees above the hips; leaning slightly forwards can also support a more comfortable toileting position.

If pelvic-floor symptoms are part of your recovery

Diastasis can exist with or without pelvic-floor symptoms. If you are also experiencing leakage, pelvic heaviness, pelvic discomfort, changes in bowel or bladder confidence, or difficulty feeling or activating your pelvic floor, these can be considered as part of your wider postnatal support picture.

Core and pelvic-floor recovery often overlap, but they are not the same thing. Abdominal strengthening alone does not tell us how the whole pelvic-floor and core system is functioning. The wider Pelvic Health Hub can help you understand the different pieces and explore the Essential Bodyworks support that is relevant to you.

Where pelvic-floor weakness, reduced activation or urinary leakage is also part of the picture, the Essential Bodyworks pelvic health chair can be a positive additional option worth exploring for an appropriately screened client. The treatment is non-invasive and fully clothed and can sit alongside active pelvic-floor work, breathing, movement and progressive core recovery. The chair is used to support the pelvic floor - it is not presented as a treatment for diastasis itself.

Staying within the right support pathway

Essential Bodyworks focuses on postnatal wellbeing, pelvic-floor support and helping you reconnect with movement and function. If something falls outside our scope, we will explain that and signpost appropriately.

Where you are already receiving postnatal, medical or specialist care, Essential Bodyworks support can sit alongside it. Individual assessment elsewhere may be useful where pain, significant functional difficulty or other symptoms need more specific investigation.

The message to take away

Your postnatal abdomen does not need to be treated as broken. It has adapted through pregnancy and birth and can continue to build strength, control and confidence through progressive, individual recovery.

Focus on comfortable breathing, good coordination, gradual strength, everyday function and the things you want your body to be able to do. Recovery does not have to be measured by a perfect-looking abdomen or a particular gap width; confidence, strength and comfortable function matter.
