When we think about core strength, the first thing that might come to mind is crunches or sit-ups. But during pregnancy, core training looks very different—and for good reason. Your body is growing and shifting to accommodate your baby, and your abdominal muscles, pelvic floor, and posture all need special care.
At Just for Mums, we teach core exercises that are safe, gentle, and truly effective. These movements help prevent aches, support your back, and prepare your body for the physical demands of labour and motherhood. Best of all, they can be done at home and adapted for every trimester.

Inhale through your nose, expanding your ribs and belly gently.
Exhale through pursed lips while gently drawing your lower belly in and lifting through your pelvic floor.

This foundational technique helps reconnect your deep core and sets the tone for every other movement.
Start in an all-fours position.
Engage your core with your exhale.

Hold for a few seconds and return to start.
Repeat 5–10 reps each side.
Stand with your back against a wall, feet hip-width apart and about a foot in front.
Slide down into a gentle wall sit.
On each exhale, activate your pelvic floor and core.
Hold for 30 seconds, rest, and repeat.
Lie on your side with knees bent or straight.
Gently lift your top leg while engaging your side body and lower belly.
Control the movement and avoid rolling backward.
10–15 reps each side.
Lie on your back (first trimester only or with modifications), knees bent.
Exhale to engage your core, then slowly slide one heel away along the floor.

You don’t need a hardcore ab routine to feel strong and capable. These simple, purposeful exercises create a solid foundation for your pregnancy, birth, and beyond. Done consistently, they’ll help you move better, feel more supported, and trust your changing body.
