Crunches Are Canceled: What to Do Instead for a Stronger Core Postpartum

September 21, 2025

Let’s just say it: if postpartum recovery had a blooper reel, crunches would be the star.

We get it. You want to feel strong again. You want your core back. And somewhere along the way, someone probably told you to "just start doing some crunches." Spoiler alert: they were wrong.

Mama, your body just performed a miracle. Whether you had a vaginal delivery or a C-section, your core (and pelvic floor) went through major changes. So if you've been wondering why your abs feel like Jell-O and crunches feel... off? You're not broken. You're just in a season that needs a different approach.

Let’s talk about why crunches are canceled and what you should do instead to rebuild from the inside out.

Why Crunches Are Not It After Baby

Crunches focus on the outermost abdominal muscles (the rectus abdominis), aka the "six-pack." But here’s the thing: postpartum recovery is all about the deep core, especially the transverse abdominis (your body’s natural corset) and pelvic floor. These are the muscles that provide stability, support your organs, and keep everything working smoothly.

When you do crunches too soon (or without proper core engagement), you risk:

  • Worsening or causing diastasis recti (ab separation)
  • Increasing intra-abdominal pressure, which can stress your pelvic floor
  • Experiencing coning or doming in your belly
  • Delaying healing and creating dysfunction down the line

The goal right now? Build a functional, supportive core that helps you carry your baby, chase your toddler, and get out of bed without pain.

So What Should You Do?

Here’s what we teach every mama inside the ABC Fit Virtual Gym: strong cores are built from the ABC Method - Alignment, Breath, and Core.

1. ALIGNMENT

Your posture matters more than you think. When your ribs are flared or your pelvis is tilted, your core muscles can’t fire properly. We teach you how to stack your ribcage over your pelvis and move in a way that supports healing, not hinders it.

2. BREATH

Yep, breathing is a workout. Learning how to connect breath to movement is the secret sauce to activating your deep core and pelvic floor. Diaphragmatic breathing, 360 breathing, and intentional exhales during exertion? Total game-changers.

3. CORE (Deep Core, That Is)

Think slow, controlled, purposeful movements. We focus on TVA engagement, pelvic floor lifts, and core integration in everything you do - whether you're lying on a mat or picking up a laundry basket. The best part? It works, even in short, nap-time-friendly sessions.

5 Core-Smart Moves to Try Instead of Crunches

Here are five ABC Fit-approved movements that are safe, effective, and postpartum-friendly (but always check with your provider before starting anything new):

1. 360 Breathing with Core Engagement
Start here. This breathwork re-establishes your brain-body connection and gently wakes up your deep core.


2. Heel Slides
Great for reconnecting your core and lower body. The key is controlling the movement while maintaining proper alignment.



3. Glute Bridges with Exhale
Strengthens your glutes and engages your pelvic floor. Exhale as you lift, inhale as you lower.


4. Bird-Dog (Modified if Needed)
A total-body move that works on stability, coordination, and core control.


5. Dead Bug (with a towel or resistance band)
Progressive core work that trains coordination and deep core activation without unnecessary strain.

Inside the Virtual Gym, we guide you through these moves (and more) with cues, modifications, and support at every stage. Whether you're six weeks or six months postpartum, you don't have to figure this out alone.

The Bottom Line

Crunches might be canceled, but your strength is not.

Postpartum is not about bouncing back. It’s about building forward - and that starts at your core. With the right support, smart movement, and a community that gets it, you can feel strong, stable, and more like you again.


If you’re ready to rebuild from the inside out, join us in the ABC Fit Virtual Gym. Our Core Restore program is designed to guide you step-by-step through breathwork, core activation, and functional movement that meets you exactly where you are.


Your strength didn’t disappear. It just needs a smarter strategy.

Come get strong as a mother.

You're standing in your bedroom, staring at your workout clothes that have been gathering dust for months. Your baby is finally napping, and for the first time in what feels like forever, you have a moment to yourself. You think, "Maybe today's the day I start working out again."  But then the questions flood in. Is it too soon? Will it hurt? What if I make something worse? What if my body just... can't do this anymore? Should I just jump back into workouts I did pre-pregnancy? Mama, if you've had these thoughts, you're not alone. The journey back to fitness for moms after having a baby is filled with uncertainty, fear, and a whole lot of conflicting advice. One person tells you to wait six weeks. Another says you should be "bouncing back" immediately. Your body is telling you something completely different. We've worked with over 300 pregnant and postpartum mamas, and here's what we know for sure: there's no one-size-fits-all answer. But there is a path forward that honors your body, respects your recovery, and helps you feel strong again. Let's talk about what that first workout after baby really looks like, and how to start your postnatal fitness journey safely and confidently.

If you’ve been eyeing your running shoes and wondering when you’ll feel ready to hit the pavement again, you’re not alone. Getting back to running postpartum isn’t just about time, it’s about rebuilding strength, stability, and connection from the inside out. During pregnancy, your core, pelvic floor, and hips go through massive changes. Before you return to impact (like running), it’s key to rebuild your foundation. Think: reconnecting to your breath , realigning your posture , and reactivating the muscles that support every stride.  At ABC Fit Collective , we focus on three pillars: Alignment, Breath, and Core. These are the foundation for every move you make, especially when it comes to getting back into high-impact exercise safely and confidently.

Can we be real for a second? Black Friday is usually about running around looking for the perfect gifts for everyone else on your list. The kids. Your partner. That friend who's impossible to shop for. But here's a question we want you to ask yourself this year: What about YOU, mama?  When was the last time you actually put yourself on your own shopping list? When did you last invest in something that supports your wellness, your fitness for moms journey, or just makes you feel good? If you're drawing a blank or feeling that familiar twinge of guilt, we get it. We've seen it in the faces of the over 300 pregnant and postpartum mamas we've worked with. This Black Friday, we're flipping the script. We're here to remind you that investing in yourself isn't selfish. It's necessary. And with all the incredible deals happening right now, there's never been a better time to prioritize your health, happiness, and self-care. Because when you take care of yourself, you show up better for everyone else too.

Hey mama. Let us guess: you’ve got your kid’s Halloween costume picked out, the snacks packed, the calendar color-coded… and your own well-being? Somewhere buried under a pile of laundry and crushed Goldfish. We see you. And we know you’re juggling a lot. Maybe you’re feeling touched out, burned out, and wondering how everyone else seems to have their life together and a solid workout routine. (Spoiler: they don’t.) But here’s the truth—you don’t need to do it all. You just need to start treating your own needs like they matter.  Because they do. That’s why we’re here to remind you that fitness isn’t another thing to check off your to-do list. It’s your ticket back to you . It’s your reset button. It’s self-care that lasts way longer than a bubble bath. (Though we’re pro those, too.)

Let’s just get it out there: leaking pee during jumping jacks, sneezes, or surprise laughs is incredibly common after having a baby. And if it’s happened to you, you’re definitely not alone. But here's the deal, mama: common doesn’t mean normal.  We hear from mamas all the time who feel embarrassed, confused, or even resigned to living with it forever. They’re told it’s "just part of motherhood," or to "do more Kegels" and hope for the best. Spoiler: there's more to the story. Let’s break it down together — with zero shame, total honesty, and a whole lot of support.

If the word "core" immediately makes you think of crunches, planks, and chasing a six-pack… we get it. That’s what most fitness culture has taught us. But mama, we’re here to blow the lid off that outdated definition.  Your core is not just your abs and it's definitely not something to "snap back" or flatten after baby. Your core is a deep, powerful system of muscles that stabilize your entire body, support your spine and pelvis, and connect your upper and lower halves. And for moms? It’s mission critical. Let’s dive into what your core really is, why it matters so much in motherhood, and how to rebuild it smarter (not harder).

Let’s take a deep breath together, mama. No really. Inhale… and exhale.  Feel that? That breath you just took isn’t just relaxing - it’s powerful. And in pregnancy, labor, and postpartum recovery, breath isn’t just a tool. It’s a superpower. Breath is the "B" in our ABC Method for a reason. It connects your mind to your body, helps regulate your nervous system, supports your core and pelvic floor, and prepares you for one of the most intense physical events of your life: birth. Let’s talk about why breath matters so much, and how to start using it as your secret weapon.

Let’s talk about something unsexy but totally game-changing when it comes to feeling good in your body again: alignment. You know that achy lower back that kicks in halfway through the day? Or the neck and shoulder tension that magically appears after wrangling your toddler into a car seat? That’s not just motherhood, mama. That’s misalignment. Postpartum bodies are incredible, but they’re also navigating big changes - from shifting organs and weakened cores to the daily circus act of holding a baby on one hip, pushing a stroller with one hand, and trying to drink cold coffee with the other. It’s no wonder your body feels like it’s yelling at you.  The good news? You can absolutely do something about it. And it starts with understanding alignment.

You just saw those two pink lines, or maybe you’re a few months into pregnancy and staring at your sneakers wondering: Should I even be working out right now? Is it safe? Will it hurt the baby? Shouldn’t I be resting instead?

Pregnancy is such a unique season of life. Your body is changing almost daily, your energy levels can swing from one extreme to the other, and your priorities shift as you prepare for your baby. One thing that can remain constant through it all is movement, safe, intentional movement that supports both your body and your mind.
