7 Best Postpartum Belly Exercises (No Crunches Needed)

Mum doing a core-safe postpartum belly exercise

If sit-ups feel pointless (or even uncomfortable) after having a baby, you are not doing anything wrong. The flat-belly playbook from before pregnancy simply does not fit a postpartum core. Your deep abdominal muscles have been stretched, your connective tissue has softened, and crunches can actually make a gap in the tummy muscles look worse. The good news is that the most useful belly exercises after a baby are gentle, slow and almost boring to watch, and they work better than any amount of crunching.

Quick answerThe best postpartum belly exercises rebuild the deep core from the inside out: think breathing, pelvic tilts and gentle holds, not crunches. Start once your doctor or midwife has cleared you, usually around six weeks (later after a c-section), and build slowly.

Why crunches are not the answer after a baby

During pregnancy the two sides of your rectus abdominis (the "six-pack" muscles) move apart to make room for your baby. This is called diastasis recti, and it is incredibly common. Crunches load those muscles in a way that can push the belly outward and put pressure on the still-healing midline. What you want instead is to wake up the muscles that sit underneath: the transverse abdominis, which works like a built-in corset, and the pelvic floor. Get those firing first and your whole midsection starts to feel firmer and more supported.

2 in 3mums still have some degree of diastasis recti at eight weeks postpartum, which is why core-safe moves matter

The 7 best postpartum belly exercises

Work through these in order. The first few are the foundation, and the later ones add gentle load only once the basics feel easy. None of them involve a single crunch.

  1. Deep core breathing (diaphragmatic breathing). Lie on your back with knees bent. Breathe in and let your ribs and belly expand, then breathe out slowly and feel your tummy gently draw in and up, as if hugging your baby toward your spine. This reconnects your breath to your deep core and is the single most important move on this list.
  2. Pelvic tilts. Same starting position. As you exhale, flatten your lower back gently into the floor by tilting your pelvis. It is a tiny movement. This teaches your deep abdominals to switch on without bulging the belly outward.
  3. Heel slides. On your back, draw the deep core in on an exhale, then slowly slide one heel away until your leg is nearly straight, keeping your back still. Slide it back and swap sides. This adds light load while keeping the midline protected.
  4. Dead bug (modified). On your back, knees bent and lifted to a tabletop. On an exhale, lower one heel toward the floor while keeping your core engaged and back flat, then return. Start small. This is a brilliant deep-core strengthener that stays gentle on the gap.
  5. Glute bridges. Knees bent, feet flat. Exhale, squeeze your glutes and lift your hips into a straight line from knees to shoulders, then lower slowly. Strong glutes take pressure off your lower back and help your whole core do its job.
  6. Standing draw-in. Stand tall, hand on your tummy. Exhale and gently pull your belly button in toward your spine without holding your breath, hold for a few seconds, then release. You can do this anywhere, even while feeding or pushing the pram.
  7. Bird dog. On hands and knees, brace your deep core, then slowly extend the opposite arm and leg, keeping your hips and back steady. Lower and swap. This trains your core to stabilise while you move, which is exactly what real life with a baby demands.

What these exercises can and cannot do

Honesty matters here, because the internet is full of promises that postpartum bodies cannot keep. These moves rebuild strength and help your tummy feel flatter and more supported. They cannot magically melt fat from one spot, and they cannot tighten loose skin. Results vary from mum to mum and depend on plenty of things outside any workout, like sleep, nutrition, hormones and how your individual body recovers.

What they CAN do

  • Strengthen the deep core and pelvic floor
  • Help close or manage a diastasis gap
  • Improve posture so you stand taller
  • Make your midsection feel firmer and more supported
  • Reduce that "everything feels weak" sensation

What they CANNOT do

  • Spot-reduce belly fat
  • Tighten or remove loose skin
  • Guarantee a specific look or timeline
  • Replace medical care for pain or a hernia
  • Work overnight, this is slow and steady

How to put it together each week

Start with the breathing and pelvic tilts daily for the first week or two until they feel natural. Then add heel slides and the standing draw-in. Once those feel easy and you are not seeing any doming or bulging along your midline, layer in the dead bug, glute bridges and bird dog. Aim for five to ten minutes most days rather than one long session. Little and often wins after a baby.

If you would rather not piece it together yourself, the Flat Belly After Baby guide sequences all of this for you, and it is part of The Complete Postpartum Body Reset bundle if you want pelvic floor, booty and full-body recovery in one place too.

When to check with a professional first

Always get clearance from your doctor or midwife before starting, usually around the six-week mark and later if you had a caesarean. See a women's-health physiotherapist if you notice a wide or deep gap that does not seem to improve, any bulging or coning along the midline when you move, leaking, pelvic heaviness, or pain. These are common and very treatable, and a physio can tailor things to your body.

The bottom line

You do not need crunches to rebuild your belly after a baby. Slow, breath-led, deep-core moves are safer and more effective for a postpartum body. Start gentle, stay consistent, get cleared first, and let your strength come back from the inside out. Results vary, but the steady, honest approach is the one that lasts.

Frequently asked questions

When can I start postpartum belly exercises?

Gentle breathing and pelvic floor connection can often begin in the early weeks, but always wait for clearance from your doctor or midwife before doing more, usually around six weeks and later after a c-section. Everyone heals differently, so go by your own clearance, not a calendar.

Are crunches bad after having a baby?

Crunches are not ideal early on because they can put pressure on a healing midline and may make a diastasis gap look worse. It is better to rebuild the deep core first with breathing, pelvic tilts and gentle holds before considering any traditional ab work.

How long until I see a flatter belly?

It varies a lot from mum to mum. Many feel stronger and more supported within a few weeks of consistent practice, but visible change depends on sleep, nutrition, hormones and how your body recovers. These exercises build strength and support, they cannot spot-reduce fat or tighten skin.

Can these exercises fix diastasis recti?

Core-safe moves like these can help many mums manage and improve a diastasis gap by strengthening the deep core. They are not a guaranteed fix for everyone. If you have a wide or deep gap, bulging along the midline, or a suspected hernia, see a women's-health physiotherapist for a personalised plan.
