I’ve Reached My Third Trimester—Now What? Can I Still Workout?

Kritie Alicea • January 13, 2025

Congrats, mama! You’ve made it to the third trimester!  Whether you’re feeling a little exhausted, a little excited, or a whole lot of both, you’re getting closer to meeting your sweet baby. But one question on your mind is probably:


Can I still work out? The answer is YES, absolutely! Fitness during the third trimester is not just safe, it’s essential for both you and baby.


At ABC Fit, we believe that the training goal in the third trimester should be about maintaining the strength you’ve built during the first and second trimesters. You’ll need all that strength and power for the big day—labor and delivery. So, let’s break it down! Here's how to keep moving, stay strong, and prepare your body for the main event: birth.

What can I do?

The good news? You can do a LOT! Most of the exercises you’ve been doing in your first and second trimesters can continue into your third trimester, with a few tweaks here and there to keep you feeling your best.

Lower Body Strength Training: Squats and Deadlifts, Oh My!

Yes, you can (and should) keep up with lower body strength training. Trust us—squats and deadlifts are your best friends right now. Why? Because you’re going to be squatting and deadlifting a lot once the baby is here. Think about it: every time you pick up your little one from their crib, bathtub, or car seat, you’re basically doing a squat or deadlift. So, why not perfect your form now, mama?


If squats and deadlifts still feel good to you, keep them in your routine. Single-leg exercises like lunges and step-ups are also great, as long as they don’t cause pelvic girdle pain. If that’s the case, no worries! Stick to exercises where both feet are planted firmly on the ground. Alignment and comfort are key!

Upper Body Strength: You’re Going to Need It

Your upper body strength is going to be crucial once your little one arrives. Babies grow fast, and so does their “baggage”! From diaper bags to car seats to baby carriers, you’re going to be carrying a lot. So, continue doing your pulling (like rows), pushing (like chest presses), and carrying (like farmer’s carries) exercises. These moves are fantastic for building the strength and posture you’ll need for all that baby-holding action.

Cardio: Let’s Dial It Back (Just a Little)

When it comes to cardio, you might want to ease up on the high-impact exercises. If you were running or doing high-intensity cycling, this is the time to slow down a bit. As your baby grows, it’s putting more pressure on your pelvic floor, and that’s something we want to protect. If you’re a runner, try switching to walking instead. Love high-intensity classes? No worries—just dial back the high-impact movements like jumping or bounding.

What Can’t I Do?

Now that we’ve covered the good stuff, let’s talk about what you might want to avoid in the third trimester.

High-Impact Moves: Time for a Timeout

First, let’s talk about high-impact movements like jumping or running. We’ve already touched on this, but it bears repeating—the third trimester is not the time for high-impact cardio. Your pelvic floor is under more pressure, and you want to keep it safe and strong for labor and recovery.

Core Exercises: Keep It Safe and Strong

When it comes to core exercises, be mindful of anything that takes you out of neutral alignment or adds excessive pressure to your abdominal wall. Planks and certain core exercises may need to be dialed back, depending on how your body feels.

  • Bird Dogs could be great for some mamas, while others might struggle with maintaining proper form in a kneeling position.
  • Safer core exercises are ones that keep you upright, like banded Pallof holds, farmer’s carries, and suitcase carries. These movements challenge your core in the safest way possible.

Twisting Movements: Proceed with Caution

While twisting exercises can be great in general, be cautious with those in the third trimester. Twists that require your hips and shoulders to move separately can put too much strain on your abdominal muscles, especially if you’re dealing with diastasis recti (the separation of your abdominal muscles). Instead, if you love twists, try to move your hips and shoulders in unison to avoid adding unnecessary pressure to your abs.

Bottom Line? Keep Moving, Mama!

You are almost there!  Listen to your body, and continue doing the movements that make you feel good and strong. Throughout this trimester, the focus is on alignment, breath, and core. Perfect your posture, avoid any discomfort, and do your best to eliminate anything that feels off. Remember, you’ve got this!


The third trimester is all about maintaining the strength and flexibility you’ve built during your pregnancy. Stay consistent with your workouts, but be mindful of what your body is telling you. Keep moving, keep breathing, and most importantly, keep feeling good as you prepare for labor.

The other day during a 1:1 session, a first-time pregnant client paused mid-squat, looked up, and asked, “Wait… what even is the pelvic floor?”  It’s a question we hear all the time . And it’s not surprising. For something so important, the pelvic floor doesn’t exactly get the spotlight it deserves; until something feels off. Maybe it’s leaking when you sneeze. Maybe it’s pressure you can’t explain. Or maybe it’s just a vague sense that your core isn’t working the way it used to. So let’s break it down. What is the pelvic floor? Where is it? What does it actually do ? And why does it matter so much especially during pregnancy, postpartum, and beyond? We’re going to answer all of it, plus share real solutions to help you feel strong, supported, and back in sync with your body again.

But here’s the good news: fueling your body during pregnancy doesn’t have to be complicated. In fact, a few simple nutrient-focused tweaks can make a world of difference for both you and baby.

Mother’s Day is the perfect time to show love—and let’s be real, as moms, we often forget to love ourselves first. Between the kids, work, and everything else, it’s easy to put ourselves at the bottom of the list. But this Mother’s Day, we want to encourage you to put yourself at the top of that list. Whether you’re buying a gift for yourself or suggesting ideas for someone else to gift you, it’s time to prioritize self-care. Let’s be honest, moms, you deserve it. So, we’ve come up with a few Mother’s Day gift ideas that focus on what really matters—taking care of YOU. We know the drill—Mother’s Day comes around, and we’re busy taking care of everyone else. Maybe you’re planning a special day for your kids, juggling the kid’s schedule, or running around handling all the other demands of the day. At the end of the day, the last person we think of is ourselves. But we’ve learned that self-care isn’t selfish—it’s essential. A couple of years ago, one of us found herself feeling totally drained, unable to focus on fitness or even enjoy little moments of peace. That’s when we realized: we need to take a step back and invest in ourselves, and Mother’’s Day was the perfect opportunity to start that journey.
