However far along you are, staying active during pregnancy can be a huge support for your body and your mood — and Mom Moves is here for you at every stage, starting from the moment you find out your little workout buddy is on the way. Here's how things shift trimester to trimester, and where to find the right workouts in the app.
Is It Safe to Work Out?
👩🏻⚕️ Always start with your provider:
Before continuing or starting any workout routine, get clearance from your healthcare provider so you feel confident moving forward safely.
For most healthy pregnancies without complications, ACOG (American College of Obstetricians and Gynecologists) supports aerobic and strength training for about 150 minutes a week. That can look like five 30-minute sessions, or even a few 10-minute chunks on busier days — whatever fits your life.
👀 Heads up on your Moves App calendar: by default, we put Weekly Moves on your calendar when you join the Moves App.
If you've been with us a while and feel comfortable continuing with Weekly Moves, you can — some moms stick with it until their belly gets in the way 😉. You can also move over to Mom Moves at any point, since Weekly Moves isn't explicitly designed for pregnancy. Make the call that's best for you.
If you're brand new to the Moves App and pregnant, we'd recommend starting with Mom Moves.
Either way, you can unfollow Weekly Moves and move to Mom Moves any time, starting in your first trimester.
What Changes Trimester to Trimester
First Trimester
Mom Moves is there for you from day one — you don't need to wait until you're "showing" to switch over.
Programming starts with slightly lower volume and intensity to work around early symptoms like fatigue and nausea.
We introduce core and mobility work early on to help reduce the risk of common pregnancy-related aches and injuries later on.
Second Trimester
Many moms feel a genuine energy boost once first-trimester symptoms ease — it's a great time to keep building strength if your provider has cleared you.
Mom Moves shifts into sumo-style squats and deadlifts to make room for your growing belly, and starts limiting higher-impact movements like plyometrics.
Research links strength training during this window to reduced lower back pain, better mood, and lower rates of preeclampsia and gestational diabetes.
Third Trimester
Sumo and plié-style squats and deadlifts continue to give baby room to grow.
Time spent lying flat on your back is limited to protect blood flow.
Around 35 weeks, programming shifts focus toward labor prep and hip-opening mobility, alongside pelvic floor cues.
Safety Guidelines to Keep in Mind
Listen to your body: if something feels off, modify or stop — this isn't the time to chase a new PR.
Stay hydrated and avoid overheating — choose well-ventilated spaces, loose clothing, and skip the sauna or hot tub.
Limit time on your back after the first trimester to protect circulation to you and baby.
Stop immediately if you feel dizzy, short of breath, or notice pain, contractions, or bleeding, and check in with your provider.
A few conditions mean you should check with your provider before you start training, including gestational hypertension, preeclampsia, ruptured membranes, placenta previa, bleeding in the second or third trimester, or risk of premature labor. When in doubt, ask your provider what's right for you.
If a Move Doesn't Feel Right
It's completely okay to skip or swap any exercise that doesn't feel safe or comfortable — you never have to push through something that feels wrong for your body. Use the Alternate Exercise option during your workout to swap in something that feels better.
Where to Find Trimester-Specific Workouts in Moves
Mom Moves is our prenatal program, developed with a Doctor of Physical Therapy specializing in Pelvic Floor and Women's Health, and it's built to adapt as you move through each trimester.
To get started: tap Programs, scroll down to Prenatal, then choose your current trimester (1, 2, or 3) and start at Week 1. You don't need to match your exact pregnancy week — just start where your trimester is.
Why Hasn't My Trimester Updated Automatically?
Mom Moves won't move you into the next trimester on its own — that switch is always yours to make. Every pregnancy is dated a little differently, so we'd rather you make the change when you know the timing is right for you than have the app do it on a fixed calendar.
That said, Mom Moves is built around trimesters for a reason: each one adjusts your programming to what your body needs at that stage, so it's worth switching over once you've entered a new trimester rather than staying put. As a general guide, most moms move into Trimester 2 around weeks 13–14 and Trimester 3 around weeks 27–28 — go by your provider's dating.
How to Switch to Your Next Trimester
End your current prenatal program
From the Programs tab, open the trimester program you're following and tap End, then confirm with End Program.Choose your new trimester
Back in Programs, scroll down to Prenatal and select the trimester you're in now (Trimester 1, 2, or 3).Start it at Week 1
Tap Start Program, then begin with Week 1 of that trimester — you don't need to match your exact pregnancy week.
You can simply pause a prenatal program instead of ending it, but when you're moving into a new trimester we'd recommend ending it and starting the next one fresh — it keeps your calendar clean and avoids two programs overlapping.
💡 Nothing is lost when you switch. Ending a program clears it from your calendar, but it doesn't delete anything — all of your completed workouts and logged data stay in your profile.
As always, this is general guidance and not a substitute for medical advice — your provider knows your pregnancy best 💙
