Ab Training During Pregnancy: What Actually Matters

One of the most common concerns during pregnancy is what’s happening to your core.

Let’s start here: It is completely normal for your front abdominal muscles to separate as your baby grows.

This natural separation is called diastasis recti. It’s not something you “caused,” and it’s not something you should panic about. It’s a normal adaptation to make room for your growing baby.

During pregnancy, the goal shifts.

We are not training for visible abs.We are not chasing a six-pack.

We are building a support system.

The Real Goal: Stability + Pressure Management

Instead of traditional ab training, pregnancy core work focuses on:

• Supporting your spine

• Managing internal pressure

• Protecting your pelvic floor

• Preparing your body for birth

• Supporting postpartum recovery

Think strength from the inside out.

Key Things to Know (Especially in the 2nd & 3rd Trimester)

As your belly grows, how you move matters more than how intense your workout feels.

Here are some important principles:

1️⃣ Exhale During Exertion

Avoid holding your breath when lifting or exerting effort.

Instead, practice 360-degree diaphragmatic breathing — expanding through your ribs and back as you inhale, then gently engaging through your deep core as you exhale.

Breath-holding increases internal pressure. Proper breathing manages it.

(Inside the Wilma Fit app, we teach this step-by-step so you don’t have to guess.)

2️⃣ Avoid Intense Crunching or Twisting

Traditional crunches, aggressive sit-ups, and deep twisting movements can place excess strain on the abdominal wall during pregnancy.

Remember — we’re not training for visible abs. We’re training for stability.

3️⃣ Avoid Lying Flat for Long Periods

Especially in the second and third trimester, lying flat on your back for extended time can reduce optimal blood flow.

A simple solution? Prop yourself up slightly with a pillow or wedge so your heart is positioned above your baby.

Small adjustments make a big difference.

4️⃣ Watch for Doming or Coning

If you notice your abdomen forming a ridge or “cone” shape during movement, that’s a sign your body isn’t managing pressure well in that position.

When this happens:

• Modify the movement

• Re-engage your breath

• Decrease intensity

• Choose an alternative

It’s not a failure — it’s feedback.

5️⃣ Include Gentle Pelvic Floor Work

Your pelvic floor works together with your deep core muscles. Supporting it throughout pregnancy helps with:

• Stability

• Birth preparation

• Postpartum recovery

  
  

In the Wilma Fit app, we begin structured deep core work starting at 13 weeks, building progressively and safely.

You Don’t Have to Figure This Out Alone

Pregnancy workouts shouldn’t feel confusing or stressful.

You shouldn’t be wondering:

• “Is this safe?”

• “Am I making separation worse?”

• “Should I be doing more?”

We’ve laid everything out for you inside the Wilma Fit pregnancy guide. The programming is intentional, progressive, and designed specifically for pregnancy — not just modified general workouts.

Because during this season, strength looks different.

It looks like support. It looks like stability. It looks like preparing your body for birth and recovery.

And that’s exactly what we focus on.
