5 Ab Exercises That Are Safe for Pregnancy (First + Second Trimester)

Is it safe to do ab exercises while pregnant? Yes! Focus on pregnancy-safe ab exercises that strengthen the deepest abdominal muscles (transverse abdominals), core and pelvic floor. These are five of the best abdominal exercises that are safe to perform during pregnancy (specifically during the first and second trimesters).

Most women shy away from ab workouts during pregnancy because they think they’re not safe.

But keeping your core strong during pregnancy is important! It can help you avoid common pregnancy aches and pains, as well as assist with labor, delivery and postpartum recovery.  

During pregnancy you want to focus on safe prenatal core exercises that strengthen the deepest abdominals; your transverse abs which wrap around your body like a natural corset.

It’s also important to strengthen your oblique muscles that run along the sides of your midsection, your glutes, and all the stabilizing muscles along your spine and pelvis.

5 Ab Exercises That Are Safe for Pregnancy (First + Second Trimester)

You can start doing these prenatal ab exercises as soon as you find out you’re pregnant; and continue them from your first trimester into your second trimester of pregnancy.

Add this prenatal core workout to your weekly workout routine 2-3 times a week to build a strong core at home.

How To Do A Kneeling Hip Lift And Core Breathing With Band Pull Apart

  1. Find a kneeling position, shoelaces down and hips stacked over knees on the mat. Option to loop a resistance band around your hands. Hold your arms straight out in front of you, hands in line with shoulders.
  2. Inhale as you hinge your hips back to tap your heels.
  3. Then exhale as you squeeze your glutes, hamstrings and core to lift your hips back up to the kneeling position. As you come back up, pull the band apart while simultaneously contracting your core or deep transverse abdominals to draw your belly in. As you draw the belly in perform a slight pelvic tilt to get your hips tucked under your ribs.
  4. With control, bring the band back to the starting position and repeat this movement.

Modification: Omit the resistance band and use a sweat towel to create tension.

Bear Crawl 3-Point Hand Tap

Targets: Every muscle in your core including the deep transverse abdomen muscles, rectus abdomens (six pack ab muscles), oblique muscles, shoulders and quads.

Your core is designed to stabilize your body as your arms and legs move away from your body. The bear crawl is an excellent exercise in core control and focused breathing.

  3. Extend your right hand in front of you, stretching the resistance band.
  4. Bring your right hand back to the starting position, then extend your right hand out to the right side, stretching the resistance band.
  5. Bring your right hand back to the starting position, then extend your right hand behind you, stretching the resistance band.
  6. Continue tapping your right hand out in this 3-point pattern for the timed interval.

Ab Exercises That Are Safe for Pregnancy FAQs

What Kind Of Ab Exercises Are Safe During Pregnancy?

Prioritize safe prenatal core exercises that strengthen the deepest abdominals; your transverse abs which wrap around your body like a natural corset. Some of my favorite pregnancy-safe ab exercises include: transverse abdominal breathing (core breathing), planks (modified or incline), side planks (modified), bear crawl, and kneeling or quadruped core exercises (like cat/cow and bird dog).

What Ab Exercises Should I Avoid During Pregnancy?

Avoid high pressure flexion movements that can put a lot of outward pressure against your already stretching abdominal connective tissue. These include full sit ups and crunches, bearing down (movements or exercise that places extreme pressure on your abdominal wall and pelvic floor) and any ab exercises that causes “coning” or “doming” of the midsection (which may be a sign of diastasis recti or abdominal separation).

Are Planks Safe During Pregnancy?

In general, yes. Planks or modified planks are safe for most women throughout pregnancy. That said, you’ll know it’s time to start modifying your core exercises when you experience “coning” or “doming” of the midsection.
