Introduction
Finding out you are pregnant often brings a new sense of awareness to your physical body. You might notice your usual morning vinyasa feels different or that your favorite deep twist now creates a pinching sensation. These changes are natural and expected. Yoga is a wonderful way to support your body through these transitions, but your practice must evolve alongside your pregnancy. Since 1986, Hugger Mugger has been a trusted companion for yoga teachers and students, and we believe that a safe practice starts with understanding your body’s unique needs. Teachers can also find additional support through our Teacher Program.
This guide will identify which yoga poses to avoid when pregnant and provide practical modifications. We will cover the physiological reasons behind these changes, including the role of hormones and blood flow. Our goal is to help you maintain a practice that feels supportive, grounded, and empowering from the first trimester through your due date. By learning to adjust your movements, you can continue to enjoy the mental and physical benefits of yoga while keeping yourself and your baby safe.
Understanding the Physical Changes
Before looking at specific poses, it is helpful to understand why modifications are necessary. Two major factors influence your prenatal practice: the hormone relaxin and changes in your circulatory system.
The Role of Relaxin
During pregnancy, your body produces a hormone called relaxin. This hormone helps loosen the ligaments in the pelvis to prepare for childbirth. However, relaxin does not only target the pelvis. It affects joints and ligaments throughout your entire body.
You might feel more flexible than usual during your second trimester. This can be misleading. Because your ligaments are softer, it is much easier to overstretch and strain your joints. Stability becomes more important than depth during this time.
Circulatory Shifts and the Vena Cava
As your baby grows, your uterus becomes heavier. By the second trimester, lying flat on your back can cause the weight of the uterus to press against the inferior vena cava. This is a large vein that carries blood back to the heart.
Compressing this vein can lead to dizziness, nausea, and decreased blood flow to the placenta. This is why many practitioners move away from lying flat on their backs for extended periods.
Key Takeaway: Your prenatal practice should focus on stability and strength rather than pushing into deep flexibility or holding poses that restrict blood flow.
1. Poses Lying Flat on the Belly (Prone Poses)
As soon as you have a visible bump, or even earlier if it feels uncomfortable, you should avoid poses where you lie face-down on your mat. These are known as prone poses.
Poses to Avoid:
- Bow Pose (Dhanurasana): This puts direct, intense pressure on the abdomen and the growing uterus.
- Locust Pose (Salabhasana): Lifting the chest and legs while resting on the belly is uncomfortable and potentially restrictive for the baby.
- Cobra Pose (Bhujangasana): While a gentle "Baby Cobra" might feel okay in the early first trimester, it eventually becomes impossible to perform without compressing the stomach.
What to Do Instead:
Instead of lying down for backbends, try Tabletop Pose or Puppy Pose. You can also practice Cow Pose to find a gentle curve in the spine without putting weight on your belly. For a deeper heart opener, Camel Pose is a great alternative, provided you keep your hands on your lower back for support and avoid overstretching the front of your torso.
2. Deep Closed Twists
Twisting is excellent for spinal health, but the way you twist must change during pregnancy. In a standard practice, we often do "closed twists" where the torso turns toward a bent leg. This action compresses the abdominal organs.
Poses to Avoid:
- Revolved Side Angle (Parivritta Parsvakonasana): This creates deep compression across the midline.
- Revolved Triangle (Parivritta Trikonasana): This requires significant core bracing and abdominal squeezing.
- Twisted Chair Pose (Parivritta Utkatasana): This puts pressure on the belly while also challenging your balance.
What to Do Instead:
Switch to "open twists." This means twisting away from your bent leg. If the class is twisting to the right, you twist to the left. This allows you to maintain spinal mobility and chest opening without "cramping" the baby’s space. You can also use a Cork Yoga Block to bring the floor closer to you, making the twist more about the upper back and less about the waist.
3. Lying Flat on the Back (Supine Poses)
As mentioned earlier, the weight of the uterus can compress the vena cava when you lie flat on your back. Most doctors and prenatal experts suggest avoiding supine positions after the 16th to 20th week of pregnancy.
Poses to Avoid:
- Full Savasana: Lying flat for the final relaxation can lead to "supine hypotensive syndrome," causing dizziness.
- Happy Baby (Ananda Balasana): While some find this okay for short bursts, it can be uncomfortable in the later stages.
- Legs-Up-the-Wall (Viparita Karani): This can be modified, but the traditional flat-back version should be limited.
What to Do Instead:
You do not have to skip relaxation. Use a Standard Bolster to create an incline. Place the bolster on a slant using blocks so that your head is higher than your heart. This removes the pressure from your major veins. Alternatively, lie on your left side with a bolster between your knees for hip support.
Myth: You must stop lying on your back as soon as you see a positive pregnancy test.
Fact: Most practitioners find supine poses safe through the first trimester. The need to modify usually begins in the second trimester as the uterus grows.
4. Intense Core Work and "Crunching"
While keeping your core strong is helpful for labor, traditional abdominal exercises like crunches or "boat pose" can be problematic. They increase intra-abdominal pressure and can contribute to a condition called diastasis recti.
Poses to Avoid:
- Boat Pose (Navasana): This requires intense abdominal gripping.
- Plank Pose (Phalakasana): If you notice your belly "coning" or "doming" in the center, it is time to drop your knees or skip the plank.
- Leg Lifts: Lowering and raising both legs while lying down puts too much strain on the abdominal wall.
What to Do Instead:
Focus on functional core strength. Bird-Dog (extending the opposite arm and leg from Tabletop) is an excellent way to stabilize the core without compression. You can also practice modified planks with your knees on a Yoga Blanket for extra padding.
5. Major Backbends
As your belly grows, the skin and muscles across your abdomen are already stretching to their limit. Deep backbends can push this stretch too far, potentially leading to muscle separation or joint strain in the lower back.
Poses to Avoid:
- Full Wheel (Urdhva Dhanurasana): This is an extreme stretch for the abdomen and can be difficult to balance as your center of gravity shifts.
- Upward Facing Dog (Urdhva Mukha Svanasana): In the third trimester, the weight of the belly can pull the lower back into an uncomfortable arch.
What to Do Instead:
Stick to Bridge Pose. It offers a gentle backbend and chest opening while keeping your feet and shoulders grounded. For added stability, place a block under your sacrum for a Supported Bridge Pose. This gives you the benefits of the inversion and the backbend with much less effort.
6. Inversions and Advanced Balancing
Inversions are poses where the head is below the heart. While experienced practitioners often continue their inversion practice, there are risks to consider, specifically regarding balance and blood pressure.
Poses to Avoid:
- Headstand (Sirsasana) and Handstand (Adho Mukha Vrksasana): The risk of falling is the primary concern. Your center of gravity shifts significantly during pregnancy, making your balance less predictable.
- Shoulder Stand (Sarvangasana): This can put pressure on the neck and restrict your breathing.
What to Do Instead:
If you want the benefits of an inversion, try a wide-legged Downward Facing Dog. Use a wall for support to ensure you don't lose your balance. If you feel any dizziness or heartburn, come out of the pose immediately.
Trimester-by-Trimester Guidelines
Your needs will change every few weeks. Here is a brief look at how to approach your practice during each phase.
First Trimester: The Energy Phase
In the first trimester, you may not look pregnant, but your body is working hard. Exhaustion and morning sickness are common.
- Focus: Stay hydrated and rest when needed.
- Avoid: Getting overheated. Avoid hot yoga or Bikram classes, as raising your core temperature can be dangerous for the baby’s development.
- Equipment Tip: Keep a bottle of water nearby and use a yoga mat from our collection for reliable grip if you feel a bit unsteady.
Second Trimester: The Modification Phase
This is when most practitioners start to make significant changes. Your bump is growing, and relaxin is peaking.
- Focus: Stability. Don't push into your maximum flexibility.
- Avoid: Belly-down poses and deep closed twists. Stop lying flat on your back if you feel dizzy.
- Equipment Tip: Use foam and cork yoga blocks to bring the floor to you in standing poses like Triangle or Half Moon.
Third Trimester: The Preparation Phase
In the final months, your goal is comfort and creating space in the pelvis.
- Focus: Pelvic floor health and breathing.
- Avoid: Anything that feels like it "crunches" your ribs or belly. Avoid long-held standing poses if your feet and ankles are swelling.
- Equipment Tip: A Round Bolster is perfect for supporting your body in seated poses or side-lying relaxation.
Using Props for a Safer Practice
Props are not just for beginners; they are essential tools for a safe prenatal practice. We have spent decades refining these tools to support every body. Our Yoga Prop Guide can help you compare supportive options for your practice.
- Yoga Blocks: Use them under your hands in forward folds to make room for your belly. They also provide stability in standing poses when your balance feels "off."
- Bolsters: Use a Standard Bolster to support your torso in an inclined Savasana or place it under your hips for a supported squat.
- Yoga Straps: If you can no longer reach your feet in a seated forward bend, a strap allows you to maintain the stretch without rounding your spine or compressing your abdomen.
- Wedges: If your wrists are feeling sensitive due to pregnancy-related swelling, a Flared Foam Wedge can reduce the angle of the wrist in Downward Dog.
Quick Answer: The most important poses to avoid are those that compress the belly, involve deep twists across the midline, or require lying flat on the back after the first trimester. Always listen to your body and move slowly to maintain balance.
Safety Checklist for Your Next Class
If you are headed to a yoga studio, follow these steps to ensure a safe experience:
- Step 1: Inform the teacher. Even if you aren't showing, tell the instructor you are pregnant so they can offer specific modifications.
- Step 2: Stay near a wall. Use the wall for balance in poses like Tree or Warrior III.
- Step 3: Keep your feet wide. In Forward Folds or Mountain Pose, take a wider stance to provide a stable base and space for your bump.
- Step 4: Watch your breath. If you are too out of breath to talk, you are working too hard. Slow down.
- Step 5: Move slowly. Transitioning from standing to the floor too quickly can cause a sudden drop in blood pressure.
Bottom line: Yoga during pregnancy is about nourishment and preparation, not performance. If a pose causes pain, pressure, or a loss of breath, it is no longer serving you.

FAQ
Is it safe to do Downward Dog while pregnant?
Yes, most practitioners find Downward Dog safe throughout pregnancy. However, you should widen your stance to make room for your belly and use blocks under your hands if you feel too much pressure in your head or wrists. If you have high blood pressure or experience heartburn, you may want to skip this pose and use Tabletop instead.
Why should I avoid twisting during pregnancy?
You do not have to avoid all twisting, but you should avoid "closed" twists that compress the abdomen. Deeply revolving the torso toward a bent leg can restrict blood flow and put pressure on the uterus. Instead, practice "open" twists by turning away from the bent leg to maintain space for the baby.
Can I still do core exercises?
Functional core work like Bird-Dog or modified planks is generally safe and helpful. However, you should avoid crunches, boat pose, and any exercise that causes your abdominal muscles to "cone" or "dome." These movements increase the risk of diastasis recti, which is the separation of the abdominal muscles.
When should I stop lying on my back?
Most healthcare providers recommend avoiding lying flat on your back after the 16th to 20th week of pregnancy. The weight of the growing uterus can compress a major vein called the inferior vena cava, which may lead to dizziness and reduced blood flow. Use a bolster to create an incline for relaxation instead.
