Returning to Exercise After Birth: A Safe and Practical Guide

At some point in the first six weeks after birth, most women receive a version of the same advice: rest until your six-week check, get cleared by your GP, then you can return to exercise. It is well-intentioned advice and it is incomplete in ways that matter.

The six-week postnatal check with a GP covers your general health, your mental wellbeing, your contraception preferences, and a basic physical assessment. What it does not typically include is a specific evaluation of your pelvic floor function, your abdominal wall integrity, your tissue healing, or your readiness for specific types of exercise. Being cleared at six weeks means your GP is satisfied with your general recovery. It does not mean your body is ready for running, weight training, or high-impact exercise.

For some women, returning to vigorous exercise at six weeks is fine. For others, it causes lasting damage to the pelvic floor and abdominal structures that is significantly harder to address after the fact than before. Knowing the difference requires more information than most women receive in a standard postnatal consultation.

What is actually happening in your body in the first twelve weeks

Understanding why the return to exercise timeline exists makes it considerably easier to follow without frustration.

Tissue healing. Whether you had a vaginal birth or a caesarean, your body has undergone significant tissue trauma. Perineal tears, episiotomy wounds, and caesarean incisions all involve multiple layers of tissue that heal progressively over weeks to months. The visible surface may close within two to four weeks, but deeper tissue healing — including the fascia, muscle, and connective tissue — continues for twelve weeks and beyond.

Hormonal state. Relaxin, the hormone that loosens ligaments and joints during pregnancy, remains elevated during the postpartum period and throughout breastfeeding. This means your joints are more susceptible to injury from high-impact or high-load exercise than they would be in your pre-pregnancy state. This is not a reason to avoid all exercise — it is a reason to progress load and impact gradually.

Abdominal separation. Diastasis recti — the separation of the rectus abdominis muscles along the midline — is present to some degree in the majority of women after birth. It is a normal adaptation to pregnancy rather than an injury. For most women it improves significantly in the first eight weeks postpartum. For some, particularly those with larger separations or significant symptom load, it requires specific rehabilitation before returning to exercises that load the abdominal wall directly.

Pelvic floor recovery. Your pelvic floor has supported the increasing weight of your pregnancy for months and, in vaginal births, has stretched significantly during delivery. Postpartum pelvic floor recovery is not automatic — it requires conscious rehabilitation. Returning to high-impact exercise before the pelvic floor has adequate strength and coordination to manage the load increases the risk of stress urinary incontinence, pelvic organ prolapse, and persistent pelvic pain.

The most important first step: a postnatal physiotherapy assessment

Before returning to any exercise beyond gentle walking, a postnatal check with a women's health physiotherapist is the single most useful thing you can do.

A GP postnatal check and a physiotherapy postnatal assessment are different things. A women's health physiotherapist assesses your pelvic floor function specifically — including both strength and the ability to relax — evaluates your abdominal separation, checks your caesarean scar if relevant, and gives you a personalised return to exercise plan based on your actual physical status rather than a generic timeline.

This assessment is available in Australia through private women's health physiotherapy practices and through some public hospital postnatal services. It may be partially covered by private health insurance extras cover. Ask your GP for a referral or search for a women's health physiotherapist in your area through the Australian Physiotherapy Association.

The ideal time for this assessment is around six to eight weeks postpartum, though earlier is appropriate if you are experiencing symptoms including leaking, pelvic heaviness, or pain.

The first six weeks: what is appropriate

The first six weeks postpartum are not a rest period — they are a recovery and gentle rehabilitation period. The distinction matters because complete inactivity is not beneficial, but the wrong type of activity causes harm.

What is appropriate from the first days:

Gentle walking, starting with short distances and building gradually as comfort allows. Pelvic floor exercises — gentle, low-intensity contractions that begin reconnecting neural pathways to the pelvic floor muscles. Diaphragmatic breathing exercises that restore coordination between the diaphragm, pelvic floor, and deep abdominal muscles. These three things are beneficial, safe, and recommended from the first days after birth for women with uncomplicated deliveries.

For caesarean births, the same principles apply with the additional consideration of incision healing. Avoid any movement that pulls on or strains the incision site. The log-roll technique for getting in and out of bed protects the wound and should be maintained for several weeks.

What to avoid in the first six weeks:

Running, jumping, and any high-impact activity. Heavy lifting beyond your baby and immediate care necessities. Traditional abdominal exercises including sit-ups, crunches, double leg lifts, and planks. Heavy resistance training. Any exercise that causes or increases symptoms including leaking, pelvic pressure or heaviness, pelvic pain, or lower back pain.

Weeks six to twelve: progressive return

If your six-week postnatal check with a GP and ideally a physiotherapy assessment indicate that recovery is progressing normally and symptoms are absent or resolved, a gradual return to more structured exercise can begin.

The key word is gradual. The body responds to progressive overload — gradually increasing load, impact, and duration over weeks rather than returning to pre-pregnancy exercise levels immediately. A woman who was running 40 kilometres per week before pregnancy does not return to that volume at six weeks. She begins with walk-run intervals and builds systematically over months.

Week six to eight:

Low-impact exercise including walking, swimming, stationary cycling, and modified Pilates or yoga is appropriate for most women with uncomplicated recoveries. Exercise intensity should be moderate — you should be able to hold a conversation throughout. Duration can be built gradually from twenty to thirty minutes.

Pelvic floor exercises should continue daily. At this stage, progressing from gentle contractions to more sustained holds and quick-fire contractions appropriate to your assessed level.

Week eight to twelve:

Body weight strength exercises can be introduced, beginning with supported versions and progressively removing support as strength and control improve. Squats, modified lunges, bridges, and modified push-ups are appropriate starting points. Load should be introduced gradually rather than returning immediately to weighted resistance training.

Walking pace and duration can increase. Some women begin returning to light jogging at this point if pelvic floor assessment indicates readiness. A useful guide is the Couch to 5K style progression rather than resuming at previous pace and distance.

Core rehabilitation, including exercises specifically addressing the deep core system including the transverse abdominis and multifidus alongside the pelvic floor, is appropriate from this stage with physiotherapy guidance.

Returning to running: the actual timeline

Running is one of the most common exercise goals postpartum and one of the most frequently returned to too soon. It is a high-impact activity that generates ground reaction forces of two to three times body weight through the pelvic floor and joints, and it requires a level of pelvic floor and structural readiness that most women have not achieved at six weeks.

The Return to Running guidelines developed by UK physiotherapists Groom, Donnelly, and Brockwell, which have been widely adopted in Australian physiotherapy practice, recommend that running not be introduced until at least twelve weeks postpartum — and only then when specific criteria are met. These criteria include the ability to walk briskly for thirty minutes without symptoms, perform twenty single leg calf raises without symptoms, jog on the spot for one minute without symptoms, and complete single leg balance for ten seconds without difficulty.

If these criteria are not met at twelve weeks, this is not a failure. It is information about what rehabilitation is still needed before running is appropriate. A women's health physiotherapist can assess readiness against these criteria and provide a specific plan for the remaining gaps.

Returning to strength training

Resistance exercise is beneficial postpartum and can be returned to progressively, but the sequencing matters.

Begin with body weight exercises before adding external load. Begin with bilateral exercises before single-leg or single-arm variations. Begin with supported exercises before unsupported ones. Begin with lower load and more repetitions before progressing to higher load.

Heavy compound lifts including deadlifts, barbell squats, and Olympic lifting require significant intra-abdominal pressure and pelvic floor load. These should not be returned to until pelvic floor and abdominal wall function has been specifically assessed and cleared by a physiotherapist, and until adequate strength has been rebuilt through progressive rehabilitation.

Breath management during resistance exercise is particularly important postpartum. Breath-holding during exertion, which many people do instinctively, dramatically increases intra-abdominal pressure and places significant load on the pelvic floor. Exhaling on exertion — breathing out during the effort phase of a lift or exercise — is the pattern to establish from the beginning of postpartum strength training.

Symptoms that mean you are doing too much too soon

Your body will signal when you are exceeding its current readiness. The following symptoms during or after exercise mean you need to reduce intensity and seek assessment from a women's health physiotherapist before continuing.

Leaking urine or faeces during exercise or afterward. A feeling of heaviness, dragging, or bulging in the pelvic area during or after exercise. Pelvic pain or lower back pain during exercise. Abdominal coning or doming along the midline during exercises — a visible ridge or peak rather than a flat abdominal wall. Joint pain, particularly in the hips, knees, or lower back, that is new or worsening.

These are not signs that exercise is harmful or that something is permanently wrong. They are signs that the current load exceeds your body's current capacity, and that stepping back and addressing the underlying function is more effective than pushing through.

The mental health dimension

Exercise after birth has documented benefits for postnatal mood, anxiety, and overall mental health. The motivation to return to exercise is often as much about mental wellbeing as physical recovery, and this is entirely valid.

It is worth noting that the mental health benefits of exercise are achievable through low and moderate intensity activity — walking, gentle yoga, swimming — in the early weeks. You do not need to run or lift heavy weights to benefit from exercise's effect on mood in the postpartum period. Starting with what your body is ready for and progressing from there provides mental health benefit while protecting physical recovery.

If postnatal depression or anxiety is a factor, exercise is a useful complement to professional treatment but not a replacement for it. PANDA on 1300 726 306 is available if you need support.
