Pregnancy is a beautiful journey, but it also brings unique physical challenges. As your body changes, your abdominal muscles stretch and work harder to support your growing bump. Many moms-to-be wonder if it’s safe to do ab exercises during pregnancy and whether strengthening the core can actually help with labor and recovery. The good news: with the right guidance, you can continue gentle ab exercises while pregnant to improve posture, reduce back pain, and prepare your body for delivery.
This guide will walk you through safe ab workouts while pregnant, exercises to avoid, and tips to make your fitness routine both safe and effective.
Are Ab Exercises Safe During Pregnancy?
Yes but with modifications. Traditional crunches or intense core training aren’t recommended during pregnancy, especially in the second and third trimesters. However, controlled ab workouts while pregnant are not only safe but also beneficial.
Here’s why core exercises matter when you’re expecting:
-
Support for your bump: Stronger core muscles help carry the extra weight more comfortably.
-
Reduced back pain: Gentle ab exercises while pregnant take pressure off your lower back.
-
Improved posture: Prevents the typical “swayback” posture caused by a growing belly.
-
Easier labor and recovery: A conditioned core helps during delivery and speeds up postpartum recovery.
Best Safe Ab Exercises During Pregnancy
1. Pelvic Tilts
A great beginner-friendly move for core stability.

Lie on your back with knees bent and feet flat (first trimester only), or do it standing against a wall for later trimesters.

Gently tilt your pelvis upward, tightening your core and glutes.
-
Hold for a few seconds, then release.

Repeat 10–12 times.
This simple ab exercise during pregnancy strengthens the lower abs and relieves back discomfort.

Repeat 8–10 times.
This is one of the safest ab exercises while pregnant, improving flexibility and easing tension.

This gentle move is a safe ab workout while pregnant that strengthens deep core muscles.
Ab Exercises to Avoid While Pregnant
Not all exercises are safe during pregnancy. Avoid the following to prevent strain:
-
Traditional crunches or sit-ups (they increase pressure on your belly).
-
Full planks (too much abdominal pressure in later trimesters).
-
Twisting movements like Russian twists.
-
Exercises lying flat on your back (after the first trimester, they can reduce blood flow).
Remember: safe ab exercises while pregnant should always focus on gentle, controlled movements instead of high-intensity training.
