Ab Separation (Diastasis Recti): Rehab Exercises That Work

• Around 60 to 70 percent of women have measurable diastasis recti just after birth, whether they had a vaginal delivery or a C-section. For most, the gap narrows on its own within 8 to 12 weeks.
• Sit-ups and crunches are usually the wrong fix. They load the wrong muscles and often make the bulge worse. Deep-core breathing and gentle progressive work close the gap.
• A simple finger-width self-check tells you roughly where you stand. A gap under 2 finger-widths is normal; over 3 to 4 finger-widths is worth a professional look.
• Watch for doming or coning along your midline during any exercise. That is your sign to make the move easier or skip it.
• Recovery runs in months, not weeks. Most diastasis improves over 3 to 12 months of consistent, correct work, and it is never too late to start.
• See a women's health physiotherapist if you have a wide gap, back or pelvic floor symptoms, or you are not progressing after 2 to 3 months of self-led work.

Your rectus abdominis is the long, flat muscle running down the front of your belly from your lower ribs to your pubic bone. It comes in two halves, left and right, joined down the middle by a band of connective tissue called the linea alba. The familiar six-pack look comes from the bands that divide each side into segments. In a non-pregnant woman the linea alba is narrow and strong, usually less than 1 cm wide.

During pregnancy your growing uterus pushes outward and stretches the linea alba sideways. Pregnancy hormones such as relaxin and progesterone make the tissue thinner and more stretchy, so the gap between the two halves widens. By the third trimester almost every woman has some widening, and right after birth around 60 to 70 percent have measurable diastasis recti, usually defined as a gap wider than about 2 finger-widths or roughly 2 cm.

After birth the linea alba gradually narrows again as your belly shrinks back, hormones settle, and the tissue regains structure. For most women the gap closes to under 2 finger-widths within 8 to 12 weeks without any special programme. For roughly 30 to 40 percent, a meaningful gap is still there at 12 months without targeted rehab. The good news is that proper rehab substantially reduces that number.

Diastasis recti is not only a cosmetic issue. Your deep core, made up of the transverse abdominis, pelvic floor, diaphragm and the small back muscles, works as one unit to support your spine, manage pressure when you lift, and keep your pelvic floor functioning. A wide, unaddressed gap is linked to back pain, pelvic floor problems, posture changes and trouble returning to heavier exercise.

It also helps to know that the postpartum belly bulge is not all diastasis. Stretched skin that takes 6 to 18 months to retract, a uterus still shrinking back, body-fat changes, relaxed abdominal muscles and posture all play a part. Some women have a flat-looking belly yet still have a real separation underneath, and some have a bulge with little or no separation. The two are related but not the same thing. Our guide to getting your belly back after birth covers the non-diastasis pieces.

Some women have a noticeable separation after a first pregnancy with no obvious cause, because connective-tissue quality varies a lot between people. That said, certain factors make a persistent gap more likely.

A self-check is reliable enough to tell you roughly where you stand and whether you have a significant gap. For a precise picture, a women's health physiotherapist gives the definitive assessment, but you can do a useful test at home in two minutes.

Lie on your back with knees bent and feet flat on the floor. Place the fingers of one hand flat across your belly at the level of your navel, pointing sideways. Lift your head just slightly off the floor, a small head raise rather than a full sit-up, which tightens the muscle and makes the gap easier to feel. Press your fingers gently down and feel for a valley between the two muscle halves. Count how many finger-widths wide it is. Repeat the test at three spots: about 5 cm above the navel, at the navel, and about 5 cm below it.

Here is how to read it: under 2 finger-widths (under about 2 to 2.5 cm) at all three spots is within the normal range; 2 to 3 finger-widths is mild to moderate diastasis that responds well to rehab; 3 to 4 finger-widths is moderate to significant and clearly benefits from a structured programme; over 4 finger-widths is significant and deserves a professional assessment.

Width is not the whole story. Also notice the depth (a deeper, softer gap suggests more stretched tissue) and whether your belly domes or cones up along the midline when you lift your head or engage your core. Doming means the load is more than your linea alba can currently handle, and it is a clear sign to ease off that movement.

Then check function, not just the gap. Gently draw your navel in toward your spine while breathing normally. Does the belly flatten smoothly, or does it bulge up through the midline? Smooth flattening suggests your deep core is doing its job; doming or having to hold your breath suggests it is not engaging properly yet. That coordination is exactly what the early exercises rebuild.

Book a professional assessment if your gap is wider than 3 finger-widths anywhere, you get marked doming with engagement, you have back pain or pelvic floor symptoms, you are stuck despite consistent effort, or you want a readiness check before returning to running or lifting. In India a women's health physiotherapy assessment typically costs Rs 800 to 3,000 at hospital chains such as Apollo, Cloudnine, Fortis, Manipal and Motherhood, or at dedicated pelvic-health clinics.

Effective rehab is not random ab work. A few principles separate exercises that close the gap from ones that widen it, and understanding them helps you choose well.

Phase 1 rebuilds the foundation of breathing and deep-core engagement. It usually takes 2 to 6 weeks and should feel solid before you progress. Almost everyone benefits from this stage, even women who are years past their last pregnancy. If you had a C-section, clear gentle exercise at your six-week check first and avoid pulling on the scar; see our notes on exercising after a C-section.

Exercise 1: Diaphragmatic breathing. Lie on your back, knees bent, one hand on your chest and one on your belly. Inhale slowly through your nose so your belly rises while your chest stays fairly still; exhale slowly through your mouth so the belly falls. Do 5 to 10 minutes, 2 to 3 times a day. This restores the diaphragm and pelvic floor teamwork that pregnancy disrupts.

Exercise 2: Transverse abdominis engagement. Lying with knees bent, inhale to let the belly expand; on the exhale gently draw your navel toward your spine, hold for 5 seconds while breathing normally, then release. Do 10 to 15 reps, 2 to 3 sets a day. It should feel like a soft internal corset, not a hard squeeze. Going too intense recruits the six-pack instead, which is the opposite of what you want.

Exercise 3: Pelvic tilts. Knees bent, inhale and let your lower back arch slightly; exhale and flatten your lower back to the floor by tilting your pelvis with a gentle deep-core and pelvic floor engagement. Do 10 to 15 reps.

Exercise 4: Heel slides. Knees bent, exhale and engage the deep core, then slide one heel slowly along the floor to straighten the leg while keeping the core engaged and the midline flat; inhale and slide back. Do 10 reps each side. Stop short of any doming.

Exercise 5: Pelvic floor coordination with breath. Inhale and let the pelvic floor relax down; exhale and gently lift it up and in along with a soft navel-to-spine draw. Hold 5 to 10 seconds while breathing, then release. Do 10 reps. This links the pelvic floor and deep core, which is essential for whole-system recovery. Our guide to pelvic floor and exercise and the basics of Kegel and pelvic floor exercises go deeper here.

Exercise 6: Modified bridge. Knees bent, exhale and engage the core and pelvic floor, lift your hips about 6 to 8 inches keeping the core engaged, then inhale and lower with control. Do 10 reps. Watch for any midline doming.

A sample daily routine: 5 minutes of breathing, then 10 reps each of transverse abdominis engagement, pelvic tilts, heel slides per side, pelvic floor coordination, and bridges. That is about 20 to 25 minutes once a day. You can also slip the engagement work in at odd moments through the day.

Stop and ease off if you get pain, doming or coning, breath holding, or a feeling you cannot find the right muscles. In Phase 1, avoid sit-ups, crunches, V-ups, leg raises, full planks, side planks, push-ups and intense Pilates ab circuits. They can wait.

Phase 2 usually runs 4 to 8 weeks and adds tougher movements while keeping the same engagement rules. Keep doing Phase 1 work as your foundation. If you want the wider return-to-fitness map, see returning to exercise after birth.

Exercise 1: Dead bug. Lie with knees bent at 90 degrees in the air (tabletop) and arms reaching to the ceiling. Exhale and engage the core, then slowly lower one arm overhead and the opposite leg toward the floor, only as far as you can keep the midline flat; inhale and return. Do 10 reps each side, 2 to 3 sets.

Exercise 2: Bird dog. On hands and knees, hands under shoulders and knees under hips, exhale and engage the core, then extend one arm forward and the opposite leg back with a level pelvis; inhale and return, alternating. Do 10 reps each side, 2 to 3 sets.

Exercise 3: Modified (knee) plank. From hands and knees, walk your knees back so your body is a straight line from knees to head. Engage the core and pelvic floor on the exhale and hold 10 to 30 seconds, building to 60. Watch for doming, sagging or breath holding. Only move to a full plank when the knee version is rock solid.

Exercise 4: Glute bridge with marching. In a bridge with the core engaged, lift one foot a few inches while keeping the pelvis level, set it down and lift the other. Do 10 reps each side.

Exercise 5: Cat-cow. On hands and knees, inhale into a gentle backbend (cow), exhale to round the spine and engage the core (cat). Do 10 to 15 reps.

Exercise 6: Wall squat hold. Back against a wall, slide down to knees at 90 degrees, engage the core and pelvic floor and hold 20 to 60 seconds for 3 reps.

Exercise 7: Bodyweight squats. Feet shoulder-width, exhale through the squat down and up with the core engaged. Do 10 to 15 reps, 2 to 3 sets.

Exercise 8: Wall push-up progression. Hands on a wall at chest height, exhale and engage the core, bend the elbows to bring your chest toward the wall, then push back. Do 10 to 15 reps and progress to incline, then knee, then full push-ups over time.

Exercise 9: Pallof press. Stand side-on to a doorway with a resistance band anchored at chest height, hold it at your chest with both hands and press it straight forward, resisting the band's pull to rotate you; hold 5 seconds and return. Do 10 reps each side. Excellent anti-rotation work without spine flexion.

Exercise 10: Bear position holds. On hands and knees, lift your knees 1 to 2 inches off the floor and hold 10 to 30 seconds, progressing to slow bear crawls. Do 3 to 5 sets.

A typical week: 3 to 4 sessions of 30 to 45 minutes alongside walking and rest days. Keep avoiding sit-ups, crunches, V-ups, double leg raises, full or side planks before you are ready, and anything that consistently domes.

Phase 3 usually starts 3 to 6 months into consistent rehab, once your deep core is reliable and basic strength is built. Here you integrate the core into full-body movement and prepare for running, lifting and sport.

Progress your Phase 2 moves: full planks for 30 to 60 seconds, side planks (begin on the knee), full push-ups, weighted squats (goblet then barbell), dumbbell rows, light deadlift patterns, and weighted dead bugs and bird dogs.

Add loaded functional work: deadlifts (Romanian then conventional) with progressive weight and proper engagement, carries such as a farmer's walk or suitcase carry that load core stability realistically, loaded lunges, kettlebell swings (if no doming), and overhead press progressions.

Add rotation and anti-rotation: cable wood chops, medicine-ball throws, single-arm presses, offset carries and bird dog with a rotation.

Add impact gradually: walk-run intervals (follow a graduated plan in our postpartum running return guide), skipping progressions, light plyometrics and sport-specific drills.

About sit-ups and crunches: only consider them once your deep core is fully restored, your planks and core work show no doming, and your belly flattens smoothly on engagement, typically a minimum of 4 to 6 months postpartum with consistent rehab. Even then, they are optional. They do little for core function beyond what compound and rotational moves give, can stress the lower back, and are not the magic six-pack maker they are sold as. Many women never go back to them and have excellent cores.

Reassess at each jump in difficulty. A narrowing gap, less doming and cleaner engagement support progressing; no change or worsening means step back a phase or get a physiotherapy assessment. Even after you are fully back, keep weaving breath-core coordination into your training, and reassess if a later pregnancy or illness sets you back.

Several moves marketed for flat abs can quietly worsen diastasis, especially early on. Spotting them saves you from undermining your own recovery.

Women's health physiotherapy is the gold standard for assessing and rehabilitating diastasis recti. Self-led work is a fine foundation, but professional guidance helps many women progress faster and avoid mistakes.

It is especially worth booking if your gap is wider than 3 finger-widths or you dome with engagement; you have back pain, pelvic floor symptoms or other functional issues; you are unsure you are engaging correctly; you have not progressed after 2 to 3 months of consistent work; you are preparing to return to running, lifting or sport; you are planning another pregnancy and want to optimise your core first; or you have had several pregnancies with a cumulative effect. A wide gap alongside symptoms like leaking, a sense of heaviness or pelvic organ prolapse or stress urinary incontinence makes an integrated assessment particularly valuable.

A good assessment covers your pregnancy and exercise history, a detailed measurement of the gap at several levels with depth and doming patterns, a pelvic floor check (the two are linked), posture and breathing patterns, and a personalised programme. Some clinics use ultrasound of the linea alba for an objective measure. For the broader recovery picture see postpartum pelvic floor recovery.

Costs in India in 2026: an initial assessment runs roughly Rs 800 to 3,000 at major chains such as Apollo, Cloudnine, Fortis, Manipal, Motherhood and Max; follow-ups are about Rs 500 to 2,500; a typical course of 4 to 8 sessions over 2 to 3 months totals around Rs 3,000 to 20,000. Online consultations (about Rs 600 to 2,000 a session) are increasingly available and useful for follow-ups once an in-person assessment is done. Some private insurance covers physiotherapy with a referral.

To find a qualified physiotherapist, ask your obstetrician for a referral, check the Indian Association of Physiotherapists Women's Health chapter, ask at hospital chains, or ask in postpartum mother groups, and verify women's health training or experience. Postpartum-trained yoga and Pilates classes (about Rs 500 to 1,500 a class) offer good community-based support once the acute rehab phase is done; look for instructors with prenatal and postnatal certification beyond a standard 200-hour course.

A few supports beyond exercise help, when used sensibly. Used wrongly, they do little or create dependency that slows recovery.

Postpartum binders: the evidence is mixed. A binder can give gentle support and feedback in the early weeks (roughly the first 4 to 8), aid comfort when walking, and possibly help early tissue retraction, which is why many women, especially after a C-section, find them reassuring. But a binder does not close the gap by itself, and worn too tightly or too long it can restrict your breathing, stress the pelvic floor and let you skip the muscle work that actually closes diastasis. If you use one, choose a gentle support you can still take a full breath in, and reduce reliance as you move into active rehab. Indian options include Mamacouture, Quench, BabyHug and Mee Mee recovery sets, roughly Rs 1,000 to 4,000. Traditional Indian belly binding works similarly, and the same caution about not overdoing it applies.

Clothing: high-waisted leggings and supportive postpartum wear give gentle support without the compression of a tight binder. Avoid extreme shapewear that restricts your breath.

Nutrition for tissue healing: connective-tissue repair benefits from enough protein (about 1.4 to 2.0 g per kg of body weight, which is harder to hit with broken postpartum meal patterns), plus vitamin C (orange, lemon, amla, guava), zinc (pulses, nuts, seeds), and good hydration of 2 to 3 litres a day, more if you are breastfeeding. Eat enough overall; do not pair aggressive weight loss with tissue healing. Our guides to postpartum nutrition for recovery and protein needs for Indian vegetarian women help here.

Weight management: excess weight raises pressure on the linea alba and can slow closure, but crash dieting harms all healing. A moderate deficit of 300 to 500 calories after the first 6 weeks, plenty of protein and a patient pace of up to 0.5 to 1 kg a week works alongside rehab. See getting your belly back after birth.

Constipation: repeated straining generates high abdominal pressure and works against you. Aim for 25 to 35 g of fibre a day, good hydration, movement and a knees-above-hips toilet posture, and treat persistent constipation (isabgol or other fibre, occasional laxatives, a doctor if chronic). See constipation and bloating relief.

Breastfeeding burns an extra 400 to 500 calories a day and keeps oestrogen low, which can slightly extend the timeline but does not stop recovery. Keep your intake adequate; this is not the time for restriction.

Surgical repair is sometimes considered after conservative rehab has been properly tried (usually at least 12 months) and a significant gap remains with real functional or cosmetic impact. It is not first-line and is not right for most women.

Surgery may be appropriate when diastasis clearly affects function despite rehab (back pain, a coexisting hernia, severe core dysfunction), when a large gap persists past 12 months of consistent work, or when cosmetic concerns significantly affect quality of life after rehab has been tried. It is generally done only after you have finished having children, because a later pregnancy can re-separate the repair. A coexisting umbilical hernia sometimes needs surgical repair in its own right.

It is not appropriate in the early postpartum period, before trying rehab, while planning future pregnancies, with an untreated eating disorder or unstable mental health, or for purely cosmetic reasons when conservative care has not been adequately tried.

The common procedure is abdominoplasty (a tummy tuck) with rectus plication, which stitches the two muscle halves together, often with removal of excess skin and fat. Smaller separations may suit a mini-abdominoplasty. Recovery is significant: roughly 4 to 6 weeks of restricted activity, 8 to 12 weeks before resuming exercise, 3 to 6 months to full activity, with compression garments for 6 to 12 weeks and a scar that fades over many months.

Costs in India in 2026: rectus plication alone is roughly Rs 80,000 to 200,000; a full abdominoplasty with plication is about Rs 150,000 to 400,000 in private hospitals. Plication for a functional problem may be partly covered by some insurance, while purely cosmetic surgery usually is not. Choose a board-certified plastic surgeon experienced in the procedure, ask about their case volume and complication rates, see before-and-after photos, and get a second opinion for major surgery.

Be realistic: surgery closes the visible gap but does not restore deep-core function on its own, so post-surgical rehab with a women's health physiotherapist remains essential. Complications are possible, and a later pregnancy or major weight change can affect the result.
