Yes, with one change: you stop asking whether a pose is on an approved list and start watching what your abdomen actually does during it. Diastasis recti is a widening of the gap between the two halves of the rectus abdominis, and almost every postpartum body has some of it. The number that matters is not how wide the gap is. It is whether the tissue between the two halves can hold tension when you load it.

That is something you can check at home in about a minute, and it is more useful than any list of forbidden poses, because it tells you about your body today rather than about postpartum bodies in general. Here is the check, what the result means, and what to change first.

What is diastasis recti, in plain terms?

Your rectus abdominis runs in two vertical halves, joined down the middle by a band of connective tissue called the linea alba. During pregnancy that band stretches and thins to make room. Afterwards it has to recover its ability to transmit force across the midline. Diastasis recti is the name for the state where it has not fully done that yet.

Notice that nothing in that description is about a hole, a tear, or damage. The two halves of the muscle have moved apart because the tissue between them lengthened. That tissue is still there, still attached, and still capable of changing. This matters because the language people meet online, split, gap, separation, tends to suggest something broken that must be closed. What you are actually training is a band of tissue to become good at holding tension again.

How do I check myself for coning?

Lie on your back, knees bent, feet flat. Rest two or three fingers just above your navel, pressing gently into the midline. Exhale and lift your head and shoulders a little way off the floor, as if starting a very small curl-up. Then watch and feel what happens along the middle of your abdomen.

You are looking for one of three things. The midline may stay flat and firm under your fingers, which is what you want. It may sink into a soft valley, meaning the tissue is not generating tension yet. Or a narrow ridge may push up along the middle, standing proud of the surrounding abdomen. That ridge is coning, sometimes called doming, and it is the single most useful signal in the whole subject. Repeat the check just below the navel too, because the two sites often behave differently.

Coning is not damage happening. It is information: this much load, in this position, is more than the midline can currently distribute. Reduce one of those two things and the coning usually disappears.

So which poses are actually unsafe?

Fewer than the lists suggest, and the answer depends on you rather than on the pose. A movement becomes a problem when it asks the midline to transmit more force than it can currently hold, which is why the same plank can be fine for one person and produce a clear ridge in another. The practical rule is simple enough to use in a class: if it cones, change it. change the range, change the lever length, or change the breath, and check again.

Does exercise actually close the gap, or is that a myth?

It genuinely narrows it, and there is decent evidence for that. A 2026 systematic review and meta-analysis in Hernia pooled nine randomised controlled trials covering 450 postpartum women and found structured exercise reduced the inter-recti distance by about 8 millimetres compared with no treatment or usual care.

The same authors are careful about what that does and does not prove, and I would rather pass their caution on than quote the number alone. The trials varied enormously in how they measured and how they defined diastasis in the first place, follow-up was short, and some of the improvement could be ordinary spontaneous recovery that would have happened anyway. Their own summary is that the true effect might be substantially different from what the pooled figure suggests. So: movement helps, the direction is clear, and nobody should promise you a specific number of millimetres.

What should I work on before anything else?

The exhale, before any shape. The deep abdominal wall and the pelvic floor work together, and they respond to breath before they respond to effort. If you can produce a long, quiet exhale and feel the lower abdomen draw gently inward without gripping or bracing, you have the connection every later movement depends on. The mechanics of that are covered in the breath pattern that settles the nervous system, and it is the same pattern used here for a different purpose.

The instinct to go straight to crunches and planks is the one worth resisting, for the same reason that core exercises often fail to stop back pain: loading a system that cannot yet coordinate itself teaches it to compensate rather than to work. Strength built on top of a midline that cones is strength built on a workaround.

That is not only a teaching preference. A 2024 scoping review in the International Urogynecology Journal singled out exactly this pattern, noting that many rehabilitation protocols introduce curl-ups and trunk twists early postpartum without first establishing whether the person can generate tension across the linea alba. The same reviewers reported no agreement on what the best protocol is, which is a fair reason to trust your own check over any fixed programme.

When should this stop being a self-check and start being an appointment?

If there is pain rather than effort, if you leak when you cough, sneeze or jump, if you feel a heaviness or dragging sensation low down, or if the coning does not change no matter how far you reduce the load. Those are pelvic-health physiotherapy questions and a self-check cannot answer them. Get your postnatal clearance before starting anything, and treat that clearance as permission to begin rather than as confirmation that everything has healed.

If you want the whole arc rather than this one question, the first twelve weeks postpartum sets out how the return is sequenced, and what belongs in each stage.

Common questions

Is yoga safe with diastasis recti?

Generally yes, once you have postnatal clearance and provided you adjust by what your midline does rather than by a list of poses. The signal to change a movement is coning, a ridge pushing up along the midline under effort. If a movement does not cone and does not hurt, it is usually fine to keep.

What does coning or doming actually look like?

A narrow ridge standing up along the centre of your abdomen when you exert, most visible from the side. It appears where the connective tissue cannot yet transmit the force being asked of it, so the pressure pushes outward instead of being distributed across the midline.

How wide a gap is too wide?

Width alone is a poor guide, which is why clinicians increasingly look at how the midline behaves under load rather than at a measurement in finger-widths. A wider gap that holds tension well can be less limiting than a narrow one that cones immediately.

Can I do planks and crunches with diastasis recti?

Eventually, often. Immediately, usually not, because both load the midline heavily at exactly the angle that produces coning. The useful version of the question is not whether you can do a plank but at what incline you can do one without coning, and then working from there.

Will the gap ever fully close?

Some close, many narrow substantially, and a residual gap that transmits force well is a good outcome rather than a failure. The pooled evidence shows a meaningful average reduction from structured exercise, with wide variation between individuals and low certainty about any specific number.

Do I need to see a physiotherapist first?

You need postnatal clearance from your doctor before starting. A pelvic-health physiotherapist becomes important rather than optional if you have pain, leaking, heaviness, or coning that does not respond to reducing the load.
