Hello, lovely mums-to-be! If you’re anything like I was during pregnancy, you’re probably wondering how to keep your body strong without overdoing it. Pregnancy is an incredible journey, but it also comes with aches, pains, and that ever-expanding belly. One of the best ways to support your body during this time is by focusing on safe and effective core exercises.
Before we dive in, let’s clear one thing up: core exercises during pregnancy aren’t about getting rock-hard abs (wouldn’t that be something?). Instead, they’re about strengthening the muscles that support your growing bump, helping with balance, reducing back pain, and even making labour and recovery a bit easier. So, let’s get into it!

Why Core Strength Matters During Pregnancy
Your core is more than just your abs—it’s a network of muscles that includes your deep abdominals, pelvic floor, obliques, and lower back. A strong core can:
- Support your posture – As your bump grows, your centre of gravity shifts, often leading to back pain.
- Reduce the risk of diastasis recti – This is when the abdominal muscles separate, which can lead to postpartum issues.
- Improve pelvic floor health – Strong pelvic muscles help prevent incontinence and aid recovery after birth.
- Ease labour and delivery – A strong core can make pushing more effective.
Safe Core Exercises for Pregnancy
Now, let’s talk about some pregnancy-friendly core exercises. Always listen to your body and modify movements if anything feels uncomfortable. And, of course, check with your midwife or GP before starting any new exercise routine.
1. Pelvic Tilts
Pelvic tilts are fantastic for strengthening the deep core muscles and easing lower back pain.
- How to do it:
- Stand or sit with a neutral spine.
- Inhale, then as you exhale, gently tuck your pelvis under and engage your lower abdominals.
- Hold for a few seconds and release.
- Repeat 10-12 times.
2. Cat-Cow Stretch
A gentle way to keep your spine flexible while engaging your core.
- How to do it:
- Get onto all fours with hands under shoulders and knees under hips.
- Inhale, arch your back, and look up (cow pose).
- Exhale, round your back, and tuck your chin towards your chest (cat pose).
- Repeat 8-10 times, moving with your breath.
3. Seated Knee Lifts
This move helps engage your deep core muscles without straining your tummy.
- How to do it:
- Sit on a chair with feet flat on the floor.
- Exhale and gently lift one knee towards your chest.
- Lower it back down and repeat with the other leg.
- Aim for 10 lifts per side.
4. Side-Lying Leg Lifts
Strengthen your obliques and hips while keeping pressure off your belly.
- How to do it:
- Lie on one side with your lower arm supporting your head.
- Keep your legs straight and lift the top leg a few inches.
- Lower slowly and repeat 10 times on each side.
5. Standing Core Engagement
A simple way to engage your core throughout the day.
- How to do it:
- Stand tall with feet hip-width apart.
- Imagine drawing your belly button towards your spine (without sucking in!).
- Hold for a few seconds, then release.
- Repeat throughout the day.
What to Avoid
Not all core exercises are safe during pregnancy. Here are some to steer clear of:
- Crunches and sit-ups – These can put too much strain on your abdominal muscles.
- Full planks – As your bump grows, these can increase pressure on the pelvic floor.
- Twisting movements – Too much rotation can put stress on your abdominal separation.
- Lying flat on your back (after the first trimester) – This can reduce blood flow to your baby.
Tips for Staying Safe
- Listen to your body – If an exercise feels uncomfortable, stop immediately.
- Engage your core properly – Avoid bulging or pushing your belly out during exercises.
- Breathe deeply – Don’t hold your breath; keep the oxygen flowing.
- Wear supportive clothing – A good maternity support band can help during workouts.
Pregnancy is a time to nourish and strengthen your body, not push it to extremes. By incorporating these gentle core exercises into your routine, you’ll be giving yourself the best chance of a more comfortable pregnancy and a smoother recovery postpartum.
