A Guide to Safely Returning to Exercise After Birth
After nine months of pregnancy and the marathon of childbirth, you might be itching to move your body again — or dreading it, or somewhere in between. Wherever you are, the key word is patience. Your body did something extraordinary, and rebuilding strength is a gradual process, not a race. Rushing back too hard, too soon is the fastest route to injury and setbacks. Here's how to return safely, stage by stage.
Always get clearance from your doctor — usually at your 6-week postpartum checkup, or later for a C-section or complicated birth — before starting a structured exercise program.
The first 6 weeks: rest and gentle movement
These early weeks are for healing, feeding, and bonding — not workouts. Your core and pelvic floor have been profoundly stretched, and (for C-section births) you're recovering from major abdominal surgery.
- Prioritise healing. Sleep when you can and don't apologise for resting. Our postpartum body guide covers what's normal as you recover.
- Start gentle pelvic floor engagement. A few days after birth, you can begin light pelvic floor activation. To find the right muscles, imagine gently stopping the flow of urine or lifting from below — then relax fully. Relaxing is as important as squeezing.
- Walk, slowly and briefly. Short, flat walks boost circulation and mood. Build up gradually.
- Practise diaphragmatic breathing. Slow belly breaths reconnect you to your deep core and pelvic floor, the foundation for everything that follows.
6–12 weeks: rebuilding the foundation
Once you have your doctor's okay, focus on the deep core and pelvic floor before anything intense.
Check for diastasis recti
Abdominal separation (diastasis recti) is common after pregnancy. To self-check: lie on your back, knees bent, and place your fingers just above your belly button. Lift your head slightly and feel for a gap between the two sides of your abdominal muscles. A gap wider than about two finger-widths, or a doming/ridging when you lift, is worth mentioning to your doctor or a pelvic floor physical therapist. Avoid crunches, sit-ups, and planks until it's resolved, as they can worsen the separation.
Foundational moves to start with
- Pelvic tilts
- Glute bridges
- Heel slides
- Bird-dogs
- Gentle, connected core breathing
Continue with low-impact cardio like walking, a stationary bike, or an elliptical.
3–6 months: gradually increasing intensity
- Listen to your body. Pain, leaking, or heaviness are signals to scale back — not to push through.
- Add bodyweight strength. Squats, lunges, rows, and push-ups (start on your knees).
- Hold off on high-impact. Most guidance suggests waiting until at least 4–6 months postpartum before returning to running, jumping, or other high-impact activity — and only once your pelvic floor and core can handle it without symptoms.
A note on breastfeeding and C-sections
- Breastfeeding and exercise mix fine. Moderate exercise doesn't harm your milk supply. Stay well hydrated, wear a supportive bra, and — if it's more comfortable — feed or pump before a workout. Fuel your body well; see our postpartum nutrition guide.
- C-section recovery is longer. Your incision needs more healing time. Wait for your surgeon's clearance (often around 8 weeks), and reintroduce core work especially gradually.
Pace yourself, and notice progress: Some of your best "workout windows" are during your baby's naps — and progress after birth is rarely linear. Log your movement, energy, and how you feel alongside your baby's sleep in MyBabyTracker so you can see how far you've come and when your body is asking for a rest day. Track it all with a free account.
Finding time to actually move
The most realistic workout slot is usually a nap. Our free nap calculator predicts when your baby is likely to sleep based on age-appropriate wake windows, so you can plan a 20-minute session with some confidence. And remember that recovery counts too — self-care for new moms has ideas that take five minutes or less.
When to see a pelvic floor physical therapist
Pelvic floor physical therapy is standard postpartum care in many countries and hugely underused in others. Consider going if you have:
- Leaking urine when you cough, sneeze, laugh, or exercise
- A feeling of heaviness, bulging, or pressure in the pelvic area
- Pain during intercourse
- Ongoing lower back or pelvic pain
- Diastasis recti that isn't improving
These are common but not something you simply have to live with — they're very treatable.
Frequently asked questions
When can I run again? Most experts suggest waiting at least 4–6 months and being able to do things like hop, jog in place, and single-leg balance without leaking or pain first. A pelvic floor PT can assess your readiness.
Is it normal to feel weaker than before pregnancy? Completely. Your deep core and pelvic floor need to be retrained, not just "toughened up." Steady, progressive work restores strength over months.
Will exercise help my mood? Gentle movement is a well-established mood booster and can ease stress and mild low mood — though it's not a treatment for postpartum depression. If your mood is low or anxious most days, please reach out for support.
When to talk to your doctor
Stop exercising and call your doctor if you experience heavy or renewed bleeding, dizziness, chest pain, a gush of fluid, worsening pain, or a feeling of pelvic heaviness or bulging. Always get clearance at your postpartum checkup before progressing beyond gentle movement, and don't hesitate to ask for a referral to a pelvic floor physical therapist.
