Safe Exercises During Each Trimester: Movement That Supports Your Pregnancy
Safe Exercises During Each Trimester: Movement That Supports Your Pregnancy
Moving With Intention, Not Fear
You want to stay active during pregnancy. But you're also worried. What if you exercise and harm the baby? What if your belly is too heavy and you fall? What if you overdo it? You're searching for clarity on what's actually safe. The good news: movement during pregnancy is not only safe—it's beneficial. Staying active reduces pregnancy discomforts, maintains your fitness, improves labor outcomes, and supports your mental health. Understanding what's safe during each trimester helps you move with intention and confidence rather than fear.
General Pregnancy Exercise Guidelines
The American College of Obstetricians and Gynecologists (ACOG) recommends:
150 Minutes of Moderate Exercise Weekly
If you exercised before pregnancy, aim for 150 minutes of moderate-intensity aerobic activity per week. This can be broken into 30 minutes, 5 days per week, or adjusted to your schedule.
Listen to Your Body
Your pregnant body is different. You might need modifications. You might need rest. Pain is a signal to stop. Exhaustion is a signal you're overdoing. Listen to what your body is telling you.
Avoid High-Risk Activities
Avoid activities with high fall/collision risk: contact sports, high-impact activities, activities where you could be hit. Avoid breath-holding and intense straining.
Stay Hydrated and Cool
Drink water before, during, and after exercise. Pregnancy increases body temperature. Overheating can be concerning. Keep yourself cool during exercise.
Avoid Lying Flat After First Trimester
As your belly grows, lying flat on your back compresses major blood vessels. Avoid supine exercises after week 12. Elevate your upper body or use side-lying positions instead.
Know Warning Signs
Stop exercising and contact provider if you experience: vaginal bleeding, dizziness, shortness of breath, chest pain, severe headache, muscle weakness, calf pain or swelling, or leaking fluid.
First Trimester Exercise (Weeks 1-13)
Early pregnancy is the time to establish active habits.
Continue Your Pre-Pregnancy Exercise
If you exercised before pregnancy, generally you can continue at similar intensity. Your body knows this activity. No need to dramatically decrease intensity just because you're pregnant.
Account for Fatigue and Nausea
First trimester exhaustion is real. Some days you'll be too tired for your usual workout. That's okay. Move when you can. Some days might mean gentle walking instead of running. That's appropriate.
Avoid Overheating
Pregnancy increases core temperature. Avoid hot yoga, outdoor running in hot weather, or intense exercise in heat. Exercise in cool environments.
Stay Hydrated
Pregnancy increases fluid needs anyway. Exercise increases this further. Drink water before, during, and after activity.
Don't Overdo It Thinking You Should "Prepare"
You don't need to increase intensity in early pregnancy. Consistency is more important than intensity.
Second Trimester Exercise (Weeks 14-27)
Second trimester is often the best time for pregnancy exercise.
The "Goldilocks" Period
Your belly is growing but not huge. Morning sickness usually resolved. You have more energy. This is ideal time to establish or maintain exercise routine.
Balance and Center of Gravity Are Shifting
Your belly is changing your balance. Your center of gravity is shifting. Avoid activities requiring precise balance. If you were a runner, you might continue. If you were a gymnast, now isn't the time to start advanced moves.
Avoid Lying Flat
By week 12-14, you should avoid supine (flat on back) positions. They compress major blood vessels. Use modified positions instead.
This Is The Time To Establish Habits
Feel relatively good? Second trimester is when to establish consistent exercise habits. These habits help throughout pregnancy and recovery.
Pelvic Floor Awareness Begins
Start being aware of your pelvic floor. Gentle pelvic floor exercises now prepare you for labor and recovery.
Third Trimester Exercise (Weeks 28-40)
Continue moving, but with more caution and modification.
Heavy Belly Affects Everything
Your belly is large now. Your balance is significantly affected. Your breathing is more labored. What felt easy in second trimester feels harder now.
Continue Activity But Modify
If you were running, maybe you're walking now. If you were doing intense strength training, maybe you're doing lighter weights with higher reps. Modify, don't stop.
Avoid Impact
High-impact activities (jumping, running intensely) become harder as belly gets heavier. Walking, swimming, modified yoga are safer choices.
Focus on Pelvic Floor Strength
Your pelvic floor is supporting significant weight. Strengthening it supports both pregnancy and postpartum recovery. Pelvic floor exercises are ideal in third trimester.
Deep Breathing and Body Awareness
Practice deep breathing. Develop body awareness. These skills help during labor and management of pregnancy discomforts.
Best Exercises by Trimester
Walking (All Trimesters)
Walking is safe, accessible, and effective throughout pregnancy. Start with whatever distance feels good. Increase gradually if you want. Walking maintains fitness without high impact.
Swimming (All Trimesters)
Water supports your weight, reduces joint stress, and provides excellent exercise. Swimming maintains fitness without fall risk. Many pregnant people swim comfortably until delivery.
Prenatal Yoga (All Trimesters)
Yoga designed for pregnancy strengthens, stretches, and prepares you for labor. Focuses on breathing, flexibility, and body awareness. Appropriate for all trimesters.
Pelvic Floor Exercises (All Trimesters)
Kegels and other pelvic floor work strengthen the muscles supporting your pregnancy and prepare them for labor. Essential throughout pregnancy.
Stationary Cycling or Elliptical (All Trimesters)
Low-impact cardiovascular exercise. Safe throughout pregnancy with modifications. Doesn't require balance like outdoor cycling does.
Modified Strength Training (All Trimesters, Adapted)
Light weights with higher reps. Avoid heavy lifting. Avoid exercises lying flat (after first trimester). Avoid intense straining.
Avoid
Contact sports, high-impact activities (intense jumping/running), activities with fall risk, exercises lying flat on back (after first trimester), breath-holding exercises, intense abdominal work.
When to Stop Exercising
Stop exercising and contact your provider immediately if you experience:
- Vaginal bleeding or spotting
- Dizziness or feeling faint
- Shortness of breath (beyond normal pregnancy breathlessness)
- Chest pain or pressure
- Severe or persistent headache
- Muscle weakness
- Calf pain or swelling (could indicate blood clot)
- Fluid leakage from vagina
- Severe abdominal pain

Move With Intention and Presence
Moving during pregnancy isn't about staying "fit" in the traditional sense. It's about supporting your body through significant changes. It's about preparing your body for labor. It's about managing pregnancy discomforts. It's about taking care of your mental and physical health during this transformative time.
Move in ways that feel good. Walk if that feels good. Swim if that feels good. Do prenatal yoga if that feels good. Listen to your body. Modify when needed. Rest when needed.
Your pregnant body is wise. Trust it. Support it. Move with presence and intention.
