Let’s Start With a Real Moment…
There I was—11 weeks pregnant, finally having a good day after weeks of nausea and exhaustion—and I thought, “Okay, let’s move a little.” I pulled on my leggings, rolled out my yoga mat, and then stopped cold. “Wait… is this safe? Should I even be exercising right now?” That’s the moment it hit me: Exercise in the First Trimester can feel confusing and even scary. With so many changes happening in your body (and a whole internet full of mixed advice), it’s totally normal to feel unsure. But here’s the truth—exercise can actually be one of the best things you do for yourself and your baby, as long as you know what’s safe, what to skip, and how to listen to your amazing body.
BAM.
“Is this safe? Should I be doing this? Could this hurt the baby?!”
Sound familiar?
Whether you were a gym junkie, a casual walker, or a “does folding laundry count as cardio?” kind of gal before pregnancy, you’ve probably wondered:
- What kind of workouts are actually safe in the first trimester?
- Can I still lift weights? Run? Do crunches?
- How much is too much?
Don’t worry—you’re not alone, and you’re not the first mama to freeze mid-squat and question everything. The good news? Exercise is not only safe during pregnancy—it’s encouraged! You just have to know what to modify and when to take it easy.
Let’s break it all down, together.
1️⃣ First Trimester: What’s Going on With Your Body?
Before we talk workouts, let’s talk about what’s happening inside you right now.
Even though your belly might not be showing yet, your body is working overtime:
- Your hormones are surging (hello, progesterone & estrogen!)
- Your core temperature may be slightly elevated
- Your heart rate is faster, pumping more blood for baby
- You may be feeling extra tired or nauseous
So yeah—it’s not the best time to push yourself to the limit. But moving your body can actually help ease some of the not-so-fun symptoms like:
✅ Fatigue
✅ Constipation
✅ Bloating
✅ Mood swings
✅ Trouble sleeping
The key is to listen to your body and move in a way that feels supportive—not exhausting.
2️⃣ The Benefits of Exercising in the First Trimester
Still on the fence? Here’s why gentle, regular movement is one of the best things you can do during pregnancy:
💪 For You:
- Boosts energy & reduces fatigue
- Helps manage weight gain
- Improves mood & reduces anxiety
- Supports better sleep
- Eases pregnancy aches & pains
👶 For Baby:
- Supports healthy fetal development
- May reduce risk of gestational diabetes
- Promotes better circulation to the placenta
- May lead to shorter labor & faster postpartum recovery
Sounds like a win-win, right?
3️⃣ What Types of Exercise Are Safe in the First Trimester?
Let’s talk about what you can do—and there’s more than you might think!
✅ 1. Walking
The safest, most accessible exercise—perfect for all fitness levels.
Try: 20–30 minutes a day at a comfortable pace.
✅ 2. Prenatal Yoga
Great for stretching, relaxing, and staying limber as your body changes.
Helps with: flexibility, back pain, and reducing stress.
📌 Avoid intense hot yoga or positions that involve lying flat on your back for long periods.
✅ 3. Swimming or Water Aerobics
Low impact, super gentle on your joints, and incredibly soothing (especially if you’re bloated or sore).
✅ 4. Stationary Biking
Great if you were active pre-pregnancy and want cardio without impact.
Stay on flat resistance, and don’t push too hard.
✅ 5. Strength Training (With Modifications)
Yes—you can still lift weights!
Just switch to lighter weights, slow movements, and skip anything that involves straining your core or holding your breath.
📌 Focus on controlled form over heavy lifting.
4️⃣ Exercises to Avoid in the First Trimester (For Now!)
There are a few things that are best to skip until later—or avoid altogether:
❌ Contact Sports or High-Risk Activities
Things like soccer, basketball, horseback riding, or skiing could result in falls or abdominal trauma. No-go for baby safety.
❌ Hot Yoga or Hot Pilates
Raising your core temperature too high in early pregnancy can be risky for baby’s development.
❌ Heavy Lifting or Holding Your Breath
Avoid holding your breath during exercise (called the Valsalva maneuver)—it reduces oxygen flow to you and baby.
❌ Exercises That Strain Your Core
Crunches, sit-ups, or high-impact ab work? Skip for now—your abdominal wall is already under pressure.
5️⃣ What If You’re Just. Too. Tired. 😩
Girl, I feel you. The first trimester fatigue is no joke. If working out feels impossible, that’s okay.
Here’s a trick: Redefine “exercise.”
✅ A 10-minute walk = movement
✅ Gentle stretching = movement
✅ Deep breathing while lying on your mat = movement
The goal isn’t to get shredded—it’s to support your body as it does the incredible work of building a baby. Even a little movement counts.
📌 Pro Tip: Try movement at the time of day you feel best—maybe it’s before lunch, after a nap, or even right before bed.
6️⃣ Signs You Should Stop and Rest
Always pay attention to your body! Stop exercising immediately if you experience:
🚨 Dizziness or fainting
🚨 Vaginal bleeding or cramping
🚨 Shortness of breath before activity
🚨 Chest pain or headache
🚨 Fluid leaking or feeling weak
🚨 Sudden swelling in legs or hands
If any of these happen, call your doctor. It’s better to be cautious.
7️⃣ How to Start a Safe First Trimester Routine
If you’re starting fresh or getting back into movement after morning sickness, here’s a simple weekly routine:
Beginner Plan (20–30 min/day, 3–5 days/week):
- Day 1: 20-min walk + 10-min stretch
- Day 2: Prenatal yoga (YouTube or app)
- Day 3: Rest or gentle movement (light housework counts!)
- Day 4: Bodyweight strength (squats, modified push-ups, light weights)
- Day 5: Short walk or swim
- Weekend: Rest or fun movement (dancing, stretching with music)

It is the time to listen, nurture, and respect your body—because it’s doing something amazing. 🧡
✅ Walk, stretch, breathe, dance—whatever feels good and doable.
