Prenatal yoga

This page puts the cautions before the benefits deliberately, because the order matters here in a way it does not on any other style page on this site.

Ask your midwife or doctor first. Not a studio, not a teacher and not this page. Activity in pregnancy is safe and encouraged in the absence of complications, and the words in the absence of complications are doing real work in that sentence. Conditions that change the answer include heart or lung disease, a shortened or stitched cervix, a pregnancy of twins or more at risk of early labour, placenta previa, pre-eclampsia, a history of preterm labour, and poorly controlled diabetes, blood pressure, seizures or thyroid disease. Only somebody with your notes in front of them can tell you which of those applies.

What is left out of a prenatal class, and why.

• Lying flat on the back for long periods, particularly after about 16 weeks. The NHS advice is explicit: the weight of the bump presses on the main vein returning blood to the heart and it can make you feel faint. Side lying or propped up instead.
• Heat. A heated room is out at every stage. If you have been reading about hot yoga, that page is where the heat evidence lives, and pregnancy is the one flat exclusion on it.
• Deep twists and strong abdominal work. Open twists from the shoulders are fine. Compression of the abdomen is not.
• Inversions. No Sirsasana and no Sarvangasana. Both pages carry the contraindication already.
• Forceful breathing and breath holding. Kapalbhati and Bhastrika are left out. Slow breathing only.
• Going to your maximum range. Ligaments are more lax, so a stretch that feels available may be further than the joint can control.

Stop and telephone your maternity team if there is bleeding, fluid loss, regular contractions, chest pain, breathlessness at rest, dizziness, calf pain or swelling, or reduced movements. A useful everyday test from the NHS is that you should be able to hold a conversation while you exercise; if you are too breathless to talk, it is too much.

The research on prenatal yoga is modest in size and reasonably consistent in direction, and the honest summary is narrower than the marketing.

A 2022 systematic review and meta-analysis of 13 studies covering 379 pregnant women looked at prenatal yoga for depression and anxiety. In women who were already depressed, there was significant improvement in depression and in anxiety after prenatal yoga. In women who were not depressed to begin with, the improvement in depression did not reach significance and the anxiety finding was not consistent under sensitivity analysis. The authors described the overall level of evidence as low and called for more randomised trials. On safety they noted that only one of the included studies assessed adverse effects and reported none, and that injuries related to yoga are rare in general.

So what can be said fairly? That a modified yoga practice appears to help mood and anxiety in pregnancy, most clearly where there was already low mood, and that no safety signal has appeared in the studies that looked. What cannot be said is that it shortens labour, guarantees an easier birth or reduces the need for pain relief. You will read all three. None of them is supported by evidence I can point you to, and I would rather leave the claim out than dress it up.

What I will offer from experience rather than from a journal is the part almost nobody mentions: the breathing is the piece that people come back and thank me for. Slow breathing practised for weeks becomes something you can reach for under pressure, and labour is pressure. That is not a medical claim about outcomes. It is an observation about having a skill available when you need one. Anulom Vilom and Bhramari are the two I would teach first, both sitting upright.

Pregnancy is not one condition, and a practice that fits at ten weeks does not fit at thirty two.

First trimester. Usually the least restricted physically and often the hardest in practice, because of nausea and exhaustion. This is not the moment to begin something ambitious. If you already practise, keep going and take out the heat, the strong abdominal work and anything that leaves you breathless. If you are new, start with breathing and with a short chair practice rather than with a class.

Second trimester. Usually the best window, and where most prenatal classes are pitched. Standing work with a wall or a chair for support, gentle backbending, open twists, and the beginnings of side lying rest. The centre of gravity has started to move, so balances that were easy in January need a wall in April. Vrikshasana with a hand on a wall is the shape to keep; the unsupported version is the one to let go of.

Third trimester. Comfort becomes the organising principle and supported practice takes over almost entirely. This is where chair yoga becomes the most useful thing on this site: joint movements, seated spinal work, standing while holding the chair, and breathing. Rest side lying with a cushion between the knees rather than in Savasana on the back. Restorative yoga adapts to this stage better than any other practice, provided the shapes are rearranged off the back.

Afterwards is a separate subject and a longer one. Do not rush back, and let somebody who has examined you tell you when the abdominal wall and the pelvic floor are ready for load. That is a clinical judgement and not a yoga one.

The question in pregnancy is less about style and more about who is in the room, but the style still matters.

• A dedicated prenatal class exists near you. Take it. Not because the postures are special but because the teacher has adapted a class before and will not have to improvise around you.
• There is no prenatal class, only a general one. Choose a slow held class over a flowing one, tell the teacher before you arrive rather than in the room, and ask the questions in the list below. Hatha and Iyengar are the two that adapt best, Iyengar because the props are already there.
• You are exhausted, or on restricted activity. Restorative and breathing only, arranged off your back, and only with clearance.
• You are in the third trimester. Chair yoga plus walking. It is the practice that stops asking things of you that your body has stopped wanting to give.
• You were a strong practitioner before. You may keep more than you expect and you must still remove the heat, the inversions, the breath retention and the abdominal work. Fitness before pregnancy does not exempt anybody from the supine caution.
• Hot yoga, ashtanga, power yoga. No. Not modified, not carefully, not this time.

My verdict. I would rather somebody pregnant did ten minutes of breathing and a chair practice with a teacher who has seen a pregnancy before than an hour of anything with somebody improvising. That is my whole position, and it is why I am not going to write a prenatal sequence on this page: a sequence written for a reader I cannot see, at a stage I do not know, with notes I have not read, is the one thing on this site that could genuinely do harm. Ask your midwife, find somebody who has taught it, and start with the breath. The three questions I would put to any teacher before booking: have you taught pregnant women before, what do you change after sixteen weeks, and what will you do if I need to stop halfway through? A good teacher answers all three in about thirty seconds.

There is no prenatal class here, and this needs saying more plainly than on any other page. The classes here are one teacher, about forty years of teaching, one hall at the residents' association in MSR Nagar in north Bangalore, in person there or live online, all ages and all levels, and the hour is asana, pranayama and relaxation taught slowly. It is a general class and it is not labelled by style.

A general class is not a prenatal class, and this site is not going to blur that line to fill a hall. If you are pregnant and want to attend, the honest position is this: speak to your midwife or doctor first, then speak to the teacher before you come rather than on the morning, so that the hour can be arranged around you from the start. What you would get is a slow class, a chair, the standing work done at a wall, the floor work rearranged so that you are not on your back, no forceful breathing, and no argument about leaving early. What you would not get is a teacher whose whole hour is designed around pregnancy, which is what a dedicated prenatal class gives you, and if one is available near you it is the better choice.

What is on this site and is genuinely useful at any stage is the breathing. Anulom Vilom and Bhramari can be practised sitting in a chair from the first week to the last, and the desk sequence is a seated practice that needs no adaptation beyond leaving out the twists. The first class is free, which at least lets you meet the teacher and ask your three questions in person, and the classes page has the timings.

Every posture below has a page on this site with its own contraindications, and the pregnancy note is part of them rather than an afterthought.

Stay, with support. Tadasana is the one that matters most, because standing well is what a shifting centre of gravity needs. Vrikshasana and Trikonasana stay with a wall or a chair. Marjariasana on all fours is one of the most comfortable shapes available in late pregnancy and is worth learning early. Balasana stays with the knees wide and a bolster under the chest.

Change. Vajrasana becomes sitting on a chair if the knees or the bump object. Uttanasana becomes a fold with the feet apart and hands on a chair seat. Savasana becomes side lying with a cushion between the knees.

Go. Sirsasana, Sarvangasana, Halasana and Matsyasana, all of which are either inversions or load the neck, along with deep closed twists, strong backbends such as full Bhujangasana once the bump makes lying face down uncomfortable, and any abdominal work. On the breathing side, Kapalbhati and Bhastrika go, and the slow practices stay.

If you want to understand why a slow held practice is the right frame for all of this, how often should you do yoga and how to start yoga at home are the two guides to read, and yoga therapy explains what it means when somebody offers to design a practice around a specific condition.
