Staying active during pregnancy has numerous benefits, including improved mood, better sleep, reduced pregnancy discomfort, and enhanced strength and stamina for labor. Strengthening your core during pregnancy is especially important because it supports your back and pelvis as your body changes. However, not all abdominal exercises are safe during pregnancy, particularly as your body begins to adjust to the hormonal and physical shifts of the first trimester.
In this article, we’ll explore pregnancy-safe ab exercises you can perform during the first trimester, how they benefit you, and key safety tips to keep in mind.
Benefits of Ab Exercises During Pregnancy
Strengthening your core muscles during pregnancy offers several benefits, including:
✅ Reduced back pain – Stronger core muscles help support the lower back as your belly grows.
✅ Improved posture – A stable core helps maintain balance and alignment.
✅ Easier labor and delivery – Strong core and pelvic muscles contribute to better pushing power during delivery.
✅ Faster postpartum recovery – Maintaining muscle strength helps you regain strength more quickly after birth.
Safety Guidelines for First-Trimester Ab Exercises
Before starting any exercise routine during pregnancy, keep the following tips in mind:
- ✅ Consult your doctor – Always check with your healthcare provider before starting any new workout routine.
- ✅ Avoid exercises lying flat on your back – After the first trimester, lying on your back can compress a major vein and restrict blood flow.
- ✅ Listen to your body – If you feel dizzy, nauseous, or overly fatigued, stop immediately.
- ✅ Avoid twisting and intense core compression – Twisting motions can strain your abdomen and back.
- ✅ Focus on controlled breathing – Proper breathing helps engage your core without unnecessary pressure.
Pregnancy-Safe Ab Exercises for the First Trimester
Here are some effective and safe core exercises you can try during the first trimester:
1. Pelvic Tilts
Strengthens the lower back and deep core muscles
How to do it:
- Lie on your back with your knees bent and feet flat on the floor.
- Tighten your abdominal muscles and tilt your pelvis upward, flattening your lower back against the floor.

- Repeat for 10–12 reps.
2. Cat-Cow Stretch
Improves spine flexibility and strengthens the core
How to do it:
- Get on your hands and knees in a tabletop position.
- Inhale, arch your back, and lift your head and tailbone (cow pose).
- Exhale, round your back, tuck your chin to your chest, and draw your belly button toward your spine (cat pose).
- Repeat 8–10 times.
3. Side-Lying Leg Lifts
Targets the obliques and hip muscles
How to do it:
- Lie on your side with your legs straight and stacked on top of each other.
- Slowly lift your top leg to about 45 degrees, keeping your core engaged.
- Lower it back down with control.
- Do 10–12 reps on each side.
4. Modified Planks
Strengthens the core and improves stability
How to do it:
- Start on your knees and forearms in a plank position.
- Engage your core and hold for 20–30 seconds.
- Gradually increase the time as you build strength.
- Repeat 2–3 times.
5. Seated Knee Lifts
Strengthens lower abs without putting pressure on the pelvis
How to do it:
- Sit on the edge of a chair or exercise ball.
- Lift one knee toward your chest, keeping your core engaged.
- Lower it back down and switch sides.
- Do 10–12 reps on each side.
6. Bird-Dog
Improves balance and strengthens the core
How to do it:
- Get on your hands and knees in a tabletop position.
- Extend your right arm and left leg simultaneously, keeping your back flat.
- Hold for 3–5 seconds, then return to the starting position.
- Switch sides and repeat for 8–10 reps on each side.
Ab Exercises to Avoid in the First Trimester
❌ Crunches and sit-ups – These put too much pressure on the abdominal muscles and pelvic floor.
❌ Twisting motions – Can strain the abdomen and reduce blood flow.
❌ Exercises lying flat on your back (after the first trimester) – May compress the vena cava and restrict blood flow to the baby.
❌ Intense or high-impact movements – Can increase the risk of injury or discomfort.
Engaging in safe, controlled ab exercises during the first trimester of pregnancy can strengthen your core, improve balance, and help you feel more comfortable as your body changes. Focus on slow, controlled movements and listen to your body. By maintaining core strength throughout your pregnancy, you’ll set the foundation for a smoother delivery and faster postpartum recovery.
