Pregnancy Fitness 101: Smart Swaps for a Strong & Healthy Mama

August 3, 2025

Okay, let us clear something up right away. Getting pregnant does not mean you have to stop exercising. In fact, it is actually very healthy for both you and your baby to stay active. Regular safe pregnancy workouts can boost your energy, reduce common aches, support your mental health, and prepare your body for labor and recovery.


But before you dive in, there are a few things we recommend to make sure your fitness routine is safe and smart.


First, always get the green light from your doctor or midwife before starting or continuing any workout routine during pregnancy. Once you have that approval, focus on avoiding exercises that could cause unnecessary risk, such as activities with a high chance of falling or movements that place too much pressure on your pelvic floor or abdominal muscles. Finally, always listen to your body. If something feels off, now is the time to modify rather than push through.


Whether you are new to exercise or a seasoned fitness pro, pregnancy is the perfect time to make adjustments to your workouts. For our athletes who are used to intense HIIT sessions or heavy lifting, this is an opportunity to slow things down while still enjoying all the benefits of movement. It is all about finding the right balance for your body.

The ABCs of a Safe Pregnancy Workout

When it comes to creating a pregnancy-safe exercise plan, remember your ABCs:


Alignment: Focus on good form and posture to protect your back and pelvic floor.


Breath: Never hold your breath, as both you and your baby need a steady flow of oxygen.


Core: Keep your core engaged in a way that supports your abdominals without adding strain.

What to Avoid During Pregnancy Workouts

Now that we have covered the basics, here are a few common movements to avoid so you can stay safe and comfortable.

1. Twisting Movements such as Russian Twists

Twisting can place too much pressure on your core and pelvic floor. Excessive twisting can also contribute to diastasis recti, which is a separation of the abdominal muscles that can occur during pregnancy. Instead, choose stability exercises that engage your core gently.

2. Planks After the First Trimester

This can vary from person to person, but planks may create too much pressure on your abdominal muscles and pelvic floor as pregnancy progresses. As your belly grows, planks may also cause discomfort in your lower back.

3. Lying Flat on Your Back After the First Trimester

Remaining flat on your back for more than 30 seconds can affect your circulation and may cause dizziness. This includes exercises like leg lifts, flutter kicks, and scissor kicks.

Why These Modifications Matter

Let us take a moment to talk about diastasis recti. While it may sound concerning, it is actually very common during pregnancy and does not mean you are doing anything wrong. Diastasis recti happens when the abdominal muscles, often referred to as your six pack, separate to make space for your growing belly. It can sometimes be linked to pelvic floor dysfunction or lower back pain.



Here is the good news. Diastasis recti is completely treatable. With the right postpartum core exercises, you can heal and regain strength after birth. The best way to reduce your risk during pregnancy is to avoid movements that place excessive strain on your abdominal muscles and allow your body to move in safe, supportive ways.

Five Modifications for Common Exercises

Exercise: Plank → Modified Plank

From a full plank position, gently drop your knees to the floor, engage your glutes, and keep your shoulders aligned over your wrists. This reduces abdominal pressure while still strengthening your core.

Exercise: Crunches → Racked Dumbbell March

Crunches increase abdominal pressure and can aggravate diastasis recti. Instead, march in place while holding dumbbells at shoulder height. Focus on posture and controlled movement to engage your core and pelvic floor.

Exercise: Burpees → Elevated Burpees

Using a sturdy chair or bench, perform a burpee with your hands elevated. Swap the jump for a heel lift to protect your core while keeping your heart rate up.

Exercise: Chops → Rotational Shoulder Press

Instead of a twisting chop, rotate your hips and shoulders together while pressing a dumbbell overhead. This protects your obliques and builds upper body strength.

Exercise: Jumping Jacks → Modified Step Jacks

Step side to side while raising your arms overhead. This keeps the movement low impact and gentle on your pelvic floor while still offering cardiovascular benefits.

You Got This, Mama

The key takeaway is that exercise during pregnancy can be both safe and effective as long as you focus on your alignment, breathing, and core engagement. This is not the time to push yourself to your absolute limit. Instead, it is about staying active in a way that feels good, supports your body, and nurtures your growing baby.

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.
