Pregnancy is a life-changing experience for your body, and your belly muscles are not an exception. Numerous women start to think about how pregnancy will affect their abs, whether it is safe to work on core strength during this period, and what is good and bad to work with in terms of exercises. The stomach muscles are important in posture, stability, balance and even during labor and delivery.

What Happens to Your Abs During Pregnancy?
What happens as you continue to progress into pregnancy is that your uterus is taking up space as your baby grows. A completely normal process leads to the stretching and thinning out of the abdominal muscles (especially the rectus abdominis, known as the six-pack muscles).
To most women, this stretching may result in diastasis recti, whereby the abdominal muscles may split along the midline. The condition, diastasis recti, is very prevalent and normally happens in the second or third trimester; however, it may remain active postpartum unless corrected effectively. You can learn more about safe recovery methods in this guide on diastasis recti exercises to restore core.

- Stretching of the muscle resulting in weak core strength
