Rebuilding Your Core After Baby: Where to Start
Quick answer:
Rebuilding your core after having a baby usually starts with reconnecting with your breathing, pelvic floor and deep core muscles before gradually adding more demanding movement. Walking, everyday activities and controlled strength exercises can all form part of rebuilding strength after pregnancy and birth.
After having a baby, it's completely normal for your core to feel weaker or less coordinated than before pregnancy. Your abdominal muscles, pelvic floor and diaphragm have all adapted over the past nine months and now need time to work together again.
Rebuilding your core isn't about jumping straight into crunches or intense workouts. It starts with reconnecting to the muscles that support your body before gradually adding more strength and movement.

Start With the Foundations
Every postpartum recovery journey begins with the basics. Building a strong foundation helps prepare your body for more challenging exercises later.
Deep core breathing
Your diaphragm, abdominal muscles and pelvic floor work together when you breathe and manage pressure through your trunk.
Practising slow, controlled breathing can help you reconnect with these muscles before adding more challenging exercises.
Try breathing into your ribs and abdomen rather than forcing your stomach in or holding your breath.
Pelvic floor exercises
The pelvic floor is part of your core system and can be affected by pregnancy and birth, regardless of how your baby was delivered.
Pelvic floor exercises involve both contracting and relaxing the muscles.
Doing more contractions is not always better. Being able to relax the pelvic floor and coordinate it with your breathing is also important.
Walking
Walking is one of the simplest ways to gradually rebuild movement and stamina after having a baby.
Start with distances that feel manageable and increase gradually according to your recovery.
If walking causes increasing pain, pelvic heaviness, pressure, leaking or other symptoms, reduce the amount you are doing and seek professional advice if symptoms continue.
Gentle core activation
Gentle core activation can help you reconnect with the deeper abdominal muscles before adding more load.
The aim is not to constantly pull your stomach in.
Instead, focus on breathing normally while gently engaging your lower abdominal muscles during movement.
Build Strength Gradually
Once the foundations feel comfortable, everyday movements can become part of rebuilding your strength.
You do not need to jump immediately into intense workouts.
Sit-to-stands
Standing up from a chair is a functional movement you probably already perform several times a day.
Practising controlled sit-to-stands can help strengthen your legs and trunk while allowing you to gradually increase the amount of work your body is doing.
Squats
Squats can be progressed according to your current strength and comfort.
You might begin with a shallow squat or use a chair or stable surface for support before gradually increasing the depth or resistance.
Focus on control rather than trying to do as many repetitions as possible.
Carrying your baby
Carrying a growing baby is physical work.
Changing sides, using comfortable carrying positions and avoiding holding your breath during effort can help manage the repeated demands placed on your body.
If you are finding everyday life physically demanding after having another child, you may also find what made life with two children easier helpful.
Functional movement
Lifting laundry baskets, getting up from the floor, pushing a pram and carrying shopping are all examples of movements that require strength and control.
Practising these movements carefully can be just as relevant to postpartum recovery as structured exercise.
What helps
Supportive exercise mat
Makes breathing exercises, stretching and floor-based core work more comfortable.
Resistance bands
A simple way to gradually add resistance as your strength improves.
Small exercise ball
Useful for gentle core activation and pelvic floor exercises during early recovery.
How to Rebuild Your Core
A simple way to think about rebuilding your core is to follow these four stages:
1. Reconnect
Start with breathing, pelvic floor exercises and gentle core activation.
2. Move
Gradually increase walking and comfortable everyday movement.
3. Strengthen
Introduce sit-to-stands, squats and controlled lifting.
4. Progress
Increase the challenge gradually as your strength, control and confidence improve.
Recovery is different for everyone. Consistency is usually more important than intensity, and there is no prize for rushing. If you experience ongoing pain, pelvic heaviness, leaking, significant abdominal bulging or symptoms that aren't improving, it's worth speaking with your GP or a pelvic health physiotherapist before progressing further.
Final thought
Rebuilding your core after having a baby isn't about getting back to where you were overnight. By focusing on strong foundations first and progressing gradually, you can rebuild strength in a way that supports your everyday life and long-term recovery.

Frequently Asked Questions
How soon can I start rebuilding my core after having a baby?
Recovery varies depending on your pregnancy, birth and individual circumstances. Gentle breathing, pelvic floor exercises and comfortable walking are often introduced before more demanding exercises, but always follow the advice of your healthcare team.
Is walking enough to rebuild my core?
Walking is an excellent starting point because it improves movement tolerance and stamina, but combining it with breathing, pelvic floor work and gradual strengthening provides a more balanced approach.
Can I do squats after giving birth?
Many people can gradually return to squats once they feel comfortable. Start with shallow, controlled movements and stop if you experience pain, heaviness or leaking.
What if my core still feels weak months after birth?
Recovery timelines vary. If you're still struggling with persistent symptoms, it's a good idea to seek advice from a healthcare professional, particularly a pelvic health physiotherapist.
