Pregnancy brings incredible changes to your body, especially your spine and core. Have you noticed any shifts? Many women notice shifts in their posture and balance as their baby grows.
Understanding how to support your spine and engage your core through prenatal yoga can make a big difference in comfort and strength during pregnancy. We designed this post to guide you through simple, practical steps to observe and improve your posture. Try this at home so you can feel more balanced and supported throughout your pregnancy.
Understanding Your Spine’s Natural Shape

Your spine naturally forms an S-shape when viewed from the side. This curve helps absorb shock and maintain balance. The lower back curves inward (natural lordosis), and the upper back curves outward (natural kyphosis). During pregnancy, the growing belly often causes the lower back to arch more than usual (aka the "Pregnancy arch"), which can lead to discomfort or pain. This is called hyperextension of the low back.
Some women already experience this before pregnancy, while others tend to tuck their glutes under stabilizing their pelvis. This tucked position might feel stable but can also cause other issues like tight hips or reduced mobility. Both patterns affect how your body moves and feels during pregnancy.
Why Neutral Spine Matters in Prenatal Yoga

In prenatal yoga, practicing a neutral spine is key. Neutral spine means maintaining the natural S-curve without exaggerating or flattening it. You might hear cues to “flatten your back,” but this is not physiologically accurate (or possible). Trying to flatten the spine out removes the natural curves and can cause tension or instability.
A neutral spine supports your baby’s weight and helps your body adapt to changes. It also protects your back and pelvis, which is important as your center of gravity shifts.
How to Observe Your Spine’s Shape
Start by standing sideways in front of a mirror. Here’s what to look for:
Check if your lower back curves inward naturally without arching too much.
Notice if your upper back has a gentle outward curve.
See if your pelvis tilts forward or backward.
Observe your head position: your chin should be level, not tilted up or down.
This simple observation helps you understand your body and how your posture may impact the aches and pains you experience during pregnancy.
Practicing Core Engagement: Hugging Your Baby
Here's how to practice core engagement and bringing your spine into a more neutral alignment:

Place your hands on your sides, just above your hips.
Gently draw your lower ribs down and in, as if hugging your baby inside (or putting on a corset). This visualization helps you engage your deep core muscles gently and safely.
Lift through your chest to open your heart space.
Lengthen through the crown of your head, keeping your chin level with the floor. Imagine a string gently pulling your head tall.
Breathe deeply and notice how this position feels.
Many pregnant women find this practice helps them regain balance as their center of gravity shifts forward. It also supports the spine and reduces strain on the lower back.
Try This Practice While Seated

You can do the same core engagement while sitting:
Sit tall on the edge of a chair or on the floor.
If seated in a chair, keep your feet flat on the floor, hip-width apart.
Follow the same steps: hug your baby, lift your chest, lengthen through the crown of the head.
Feel the support around your spine and pelvis.
This seated practice is easy to do throughout your day, whether at work, home, or during prenatal yoga classes.
Why Hip Mobility Matters
Posture impacts hip mobility, which plays a crucial role in pregnancy and childbirth. While this post focuses on posture and core engagement, improving hip flexibility and strength is equally important. We will explore hip mobility in detail in a future post. For now, remember that a neutral spine combined with open, mobile hips creates a strong foundation for your pregnancy journey.
Tips for Daily Practice
Check your posture regularly using the mirror technique.
Practice hugging your baby core engagement several times a day.
Combine this with gentle prenatal yoga poses that encourage length and balance.
Avoid locking your knees or tucking your pelvis excessively.
Listen to your body and adjust as your pregnancy progresses.
As your body shifts and grows during pregnancy, your spine and core undergo significant changes that can often lead to discomfort if your posture isn't supported. Exploring the importance of maintaining a neutral spring, the natural S-curve, rather than over-arching or tucking your pelvis, which can cause tensions in your hips and lower back. By practicing the hugging onto baby technique to gently engage your core muscles an lengthening your posture while standing or sitting, you can improve your balance and ease common pregnancy aches. Consistent, mindful check ins on your alignment will help you feel more supported and prepared as you move through your pregnancy journey.
