During pregnancy, the body experiences deep physiological and anatomical changes to provide support to the developing fetus. One of the most important factors that lead to a healthier pregnancy and easier childbirth is core stability and breathing awareness. As common wisdom goes, having strong core during pregnancy is not about developing a six-pack or doing rigorous ab exercises. Rather, it involves stabilizing the deep core muscles, such as the pelvic floor, transverse abdominis, diaphragm, and multifidus, to ensure balance, posture, and breathing control.
When combined with mindful breathing practices, core stability can alleviate back pain, enhance digestion, stabilize the spine, and facilitate labor. This chapter will discuss the importance of core stability, safe methods for strengthening the core, and the immense relationship between the breath and the core.
The central musculature is more than the abdominal wall. It is a cylindrical structure that encases internal organs, stabilizes the spine, and enables movement. The most important contributors to core stability in pregnancy are:
Transverse Abdominis (TVA): The innermost abdominal layer, encircling the torso in a corset-like fashion, stabilizing the spine and internal organs.
Pelvic Floor Muscles: These are the foundation of the core and cradle the bladder, uterus, and bowels. They need to be strong as well as flexible.
Diaphragm: The major breathing muscle, which operates synergistically with the TVA and pelvic floor.
Multifidus: Small stabilizing muscles running down the spine that assist with posture and balance.
During pregnancy, the expanding uterus moves the abdominal muscles outward, commonly weakening them. Relaxin and progesterone hormones relax ligaments further, making structural stability easier to lose. Pregnancy-friendly core training maintains this support system.
Decreases Lower Back Pain: Core strengthening stabilizes the pelvis and spine, taking pressure off the lower back.
Improves Posture: As the baby develops, the center of gravity changes. Having a strong core assists in preventing the leaning backward and staying more upright.
Prepares for Labor: Having a strong and reactive core, particularly the pelvic floor, aids effective pushing and reduces complications during childbirth.
Supports Quicker Postnatal Recovery: Women with preserved core tone recover muscle tone and alignment quicker after giving birth.
Breath is the door to accessing the core. The diaphragm and pelvic floor move together with inhalation and exhalation. On inhalation, the diaphragm goes down and the pelvic floor relaxes. On exhalation, both return to their resting tone. Diaphragmatic breathing practice increases one’s awareness of this movement, tones the pelvic floor, and promotes relaxation.
Instead of sit-ups or crunches, which are unsafe during pregnancy, try these gentle and effective methods:
How it helps: Increases awareness of spinal and pelvic alignment while activating deep abdominal muscles.
Modification: Place a folded blanket under the knees for support.
Breathing tip: Breathe in cow (spine arches), breathe out cat (spine rounds).
How it helps: Activates the multifidus and TVA while enhancing balance.
Modification: Support against a wall or lift one limb at a time.
Breathing tip: Breathe in to set up, breathe out as you lengthen.
How it helps: Develops postural awareness, spinal alignment, and subtle core activation.
Technique: Stand facing the wall, feet hip-width apart. Lift arms like a goalpost and move arms up and down, keeping core engaged.
How it assists: Develops lateral core strength and pelvic stability.
Modification: Leave the bottom knee on the ground. Practice lifting the hips up a little and maintaining body alignment.
Breathing tip: Breathe deeply to prevent holding your breath while exerting effort.
Sit or lie in supported alignment.
Breathe in slowly through the nose, filling the belly.
Exhale via the nose or mouth, lightly activating the pelvic floor and TVA.
Practice: 5 minutes a day to develop awareness and strengthen breath-core connection.
Produces internal heat and improves concentration.
Use softly during early pregnancy only.
Avoid during third trimester if there is any discomfort.
Inhale: release the pelvic floor.
Exhale: lightly draw up and in via the pelvic floor and TVA.
Cue: Imagine lifting a small blueberry with your pelvic muscles at the exhale.
Core stability and aware breathing are not only physical skills—they are doorways to greater body awareness, presence, and empowerment in pregnancy. As a prenatal yoga student, mindful attention to gentle core support and breathing ensures safer practice, builds maternal confidence, and readies the mother physically and emotionally for birth and beyond.
By choosing supportive asanas and aligning movement with breath, a pregnant woman reconnects with her inner strength—subtle, quiet, yet profoundly powerful.
