Postnatal Exercise in Singapore: When to Start & How to Progress

Almost every new mum in Singapore ends up asking the same question: when can I start exercising again? There is no single date that applies to everyone, and anyone who gives you one without knowing your delivery is guessing. What actually helps is understanding what bodies like ACOG (the American College of Obstetricians and Gynecologists) and the NHS say about timing, what to watch for along the way, especially diastasis recti, and a sensible way to build back up. We will also be honest about where BMB's own recovery treatments fit into that picture, and where they do not.

Start with your doctor, not a date

The most consistent piece of advice across every reputable source is also the simplest: your own doctor sets the timeline, not a blog post. ACOG's patient guidance is direct about this split. If you had a healthy pregnancy and a normal vaginal delivery, it is usually safe to begin exercising a few days after giving birth, or as soon as you feel ready. But if you had a caesarean birth or complications, ACOG says to ask your ob-gyn when it is safe to begin.

The NHS draws the same line. For a straightforward birth, you can start gentle exercise, including walking, gentle stretches, and pelvic floor exercises, as soon as you feel up to it, though it is worth getting advice at your 6-week postnatal check before anything high-impact like aerobics or running. If your delivery was more complicated, or you had a caesarean, the NHS is explicit that recovery time will be longer, and you should talk to your midwife, health visitor, or GP before starting anything strenuous.

There is no fixed week that suits every mum. ACOG, the NHS, and HealthHub Singapore all say the same thing in different words: start gently, and let your own doctor decide when you're ready for more, especially after a C-section.

What the guidelines actually say about pace

Once you have the go-ahead, the guidance converges on a similar shape: start small, build gradually, and work toward a weekly target rather than a single big session. ACOG suggests aiming to stay active for 20 to 30 minutes a day, starting with simple postpartum exercises that strengthen the major muscle groups, then gradually adding moderate-intensity activity. If you trained vigorously before pregnancy, or you are a competitive athlete, ACOG says you can work back up to vigorous-intensity exercise over time. The one rule that never changes: stop exercising if you feel pain.

The longer-term target, once you are back in the swing of things, is at least 150 minutes of moderate-intensity aerobic activity a week, which ACOG notes can be split into 30-minute workouts on 5 days, or several shorter 10-minute sessions through the day. HealthHub Singapore, in an article reviewed by Dr Angelia Chua of the National Healthcare Group Polyclinics, gives the same 150-minutes-a-week target, and adds that most of the physical changes of pregnancy return to what they call "normal" by around 6 weeks post-delivery. HealthHub's own suggestions for easing back in include low-impact aerobics, modified Pilates, resistance training, postnatal yoga, walking, and swimming, started slow and built up gradually, with a doctor check-in first if you're unsure, have a medical condition, or are on medication.

Diastasis recti: the ab gap many new mums notice

Somewhere in this process, many mums notice a gap or softness down the centre of the stomach. This is diastasis recti, and it is common, not a sign that something has gone wrong. The NHS explains it plainly: it's common for the two muscles that run down the middle of your stomach to separate during pregnancy, usually about two finger widths, because the growing womb pushes the muscles apart and makes them longer and weaker. The gap usually starts closing on its own, and the NHS notes it will typically be back to normal by around the time your baby is 8 weeks old.

Two things from the same NHS guidance are worth carrying into your own exercise plan. First, try to avoid exercises such as sit-ups, planks, and high-impact exercise to start with, along with straining on the toilet and heavy lifting, because these can put extra pressure on a stomach that is still knitting back together. Second, if the gap is still obvious 8 weeks after birth, the NHS recommends contacting your GP, since an unresolved separation carries a higher risk of back problems and some women also experience abdominal pain or discomfort, in which case a GP can refer you to a physiotherapist for targeted exercises. If you would like the self-check technique and more detail on how BMB approaches core recovery, our diastasis recti page covers both.

Pelvic floor comes first, always

Whatever your delivery, pregnancy alone stretches and weakens the pelvic floor, the muscles that support your bladder, bowel, and womb. The NHS recommends starting pelvic floor exercises early and often: squeeze and draw in as if stopping the flow of urine or holding in wind, hold for up to 10 seconds, and build up to 10 repeats at least 3 times a day. The same NHS guidance notes that regular pelvic floor and deep stomach muscle exercises can also help reduce the size of a diastasis recti separation, which is one reason this is usually the very first exercise a new mum is advised to do, well before any structured workout.

A sensible gentle-to-active progression

Putting the guidance above together, a reasonable shape for most uncomplicated recoveries looks like short gentle movement in the first days, once your own doctor has confirmed there is nothing to wait for, followed by continued gentle activity like walking and pelvic floor work through to your 6-week postnatal check, then a gradual build toward the 150-minutes-a-week target once you are cleared for more. None of this replaces your doctor's own assessment of your specific recovery, and it is not a countdown to follow blindly. If you had a caesarean or a complicated delivery, every source we've cited says the same thing: your timeline starts with a conversation with your doctor, not a calendar.

Where BMB's treatments support the physical side

We offer several treatments that new mums in Singapore often book alongside their own recovery and exercise plan, and we would rather be precise about what each one actually does than oversell it. None of them are a substitute for your doctor's clearance to exercise.

Our Body Slim Detox is a targeted massage for the tummy and thighs, typically booked from around six weeks postnatal once the initial recovery phase is behind you. If you had a C-section or any complications, we wait until you have your gynae's clearance before booking it, the same principle as exercise. It supports circulation, lymphatic drainage, and gentle contouring; it is not a treatment for closing a diastasis recti gap, which is a separate, medically-relevant recovery process best tracked with your own doctor or our dedicated Core Recovery programme.

Our postnatal massage, a blend of TCM and Javanese technique with optional Jamu paste and bengkung binding, can typically start around 7 days after a straightforward vaginal delivery, or around 3 weeks after a C-section, or whenever your gynae recommends. It is built for circulation, wind relief, and womb recovery comfort during confinement, alongside your exercise progression rather than instead of it.

Frequently asked questions

When can I start exercising after having a baby?

It depends on your delivery. ACOG says that after a healthy pregnancy and a normal vaginal delivery, it is usually safe to begin exercising a few days after giving birth, or as soon as you feel ready. The NHS agrees that gentle exercise like walking, stretching, and pelvic floor work can start as soon as you feel up to it, but recommends waiting for your 6-week postnatal check before any high-impact exercise. If you had a caesarean or a complicated delivery, both ACOG and the NHS say to ask your doctor first.

Is it safe to exercise after a C-section?

Eventually, yes, but the timing is individual. ACOG advises asking your ob-gyn when it is safe to begin exercising after a caesarean birth, and the NHS says recovery time is longer after a caesarean, so you should talk to your midwife, health visitor, or GP before starting anything strenuous. There is no single week that applies to every C-section recovery, so treat your own doctor's clearance as the deciding factor, not a calendar date.

What is diastasis recti and should I check for it before exercising?

Diastasis recti is when the two muscles running down the middle of your stomach separate during pregnancy, which the NHS describes as common and usually around two finger-widths. The gap usually narrows by around 8 weeks after birth. The NHS advises avoiding sit-ups, planks, and high-impact exercise to start with, and contacting your GP if the gap is still obvious at 8 weeks. Our dedicated diastasis recti page has a simple self-check and more detail on BMB's Core Recovery programme.

Do BMB's massage treatments replace my doctor's exercise clearance?

No. Our postnatal massage and Body Slim Detox sessions support circulation, comfort, and alignment during recovery, but none of them are a substitute for your own doctor confirming you're ready to exercise, especially after a C-section or a complicated delivery. We always recommend getting that clearance first and treating our therapies as support alongside it.

How much exercise should I be aiming for once I'm cleared to start?

ACOG recommends at least 150 minutes of moderate-intensity aerobic activity a week once you're exercising again, which can be split into 30-minute sessions on 5 days or several shorter 10-minute bursts. HealthHub Singapore gives the same 150-minutes-a-week target and adds that you should start slow and build up gradually, alongside muscle-strengthening and stretching activities. Stop and rest if anything hurts.
