History and origin
Prenatal yoga is ordinary yoga rewritten for pregnancy: shorter stays, no pressure on the belly, and shapes that leave room to breathe. It grew as teachers stopped asking pregnant students to follow a general class unchanged. There is no separate ancient school behind it, and no single lineage owns the variations. The work is adaptation.
Postnatal classes begin after birth, and only when a midwife or doctor has said that movement is welcome. They respect an abdomen and a pelvic floor that are still recovering. Lying on the belly waits. Deep closed twists, long breathless holds, strong inversions, and hot rooms are left out in pregnancy and are not rushed back afterwards. None of this is medical advice. What you may do belongs with your own clinician.
Philosophy
The person in the room is already doing enough. Practice can support comfort, a little strength, and a habit of breathing you may want later. It does not try to improve upon pregnancy, to promise an easier birth, or to train the baby. If a shape feels wrong, you leave it, even when the rest of the room continues. Clinical guidance stays with the midwife, the doctor, or the physiotherapist who knows your case.
How a class proceeds
Expect a warm, practical hour: cat and cow, side stretches that keep the belly free, a wide stance with the knees bent, and rest on the side. Breath is unforced, and you are not asked to hold it. A chair or the wall is a normal option, not a demotion. The teacher should know that people are at different stages and should not run one silent standard for the whole room.
After birth the same work is slower. The abdomen is not loaded, and the pelvic floor is not drilled as fitness. You are not compared with someone who gave birth a different number of weeks ago. Heat, jumping, and long balances without support stay out until a clinician says otherwise. You can sit a shape out. The class changes yoga. It does not write a treatment plan.
Intensity
Intensity is gentle to moderate, never hot and never breathless. The legs may work in a wide stance, and you may feel a modest length along the side of the body. You should be able to speak in full sentences. Joints are not driven to an end range, and nothing is held so long that you must grip. Pregnancy already costs energy, so the hour should leave some. Dizziness, a new leak of urine, bleeding, or pain is a reason to stop and tell a clinician, not a reason to try a deeper variation.
Benefits
People use these hours to be off their feet without lying still the whole time, to stand and sit with less fuss, and to practise a breath they already know. Side-lying rest becomes an ordinary position rather than a special trick. Company at a similar stage can steady the week. None of that predicts the birth, repairs a pelvic injury, or replaces antenatal care. The modest claim is that you moved with room for the belly, and that you stopped when you needed to.
Who it suits
The class suits pregnant people who have been cleared for gentle movement, and new parents once a clinician agrees that practice can start. It also suits anyone who wants a teacher who will change the shapes rather than praise pushing on. It is a poor fit if you want heat, inversions, or a strong flow with a few prenatal cues added at the end.
Bring the advice you already have. A teacher cannot clear you for exercise, cannot diagnose pelvic pain, and should not override a restriction from your care. Bleeding, a sudden headache, chest pain, or fluid leaking are reasons to stop and seek clinical help, not to finish the sequence. The yoga is optional. The care is not.
Beside similar forms
A general class keeps closed twists, belly-down shapes, long balances, and sometimes heat. Prenatal work takes those out and widens the base. Postnatal work is slower than prenatal work because tissues are recovering, and it is not a pelvic-floor physiotherapy session. Yoga therapy is one to one and built around a stated aim. This is a group adaptation of simple yoga. It can sit beside clinical care. It does not stand in for it.
Best positions
Cat and cow
From hands and knees, let the belly hang free. On an exhale the back rounds, on an inhale it returns toward flat or a small arch, only as far as the belly allows. Move with the breath and stop if the middle feels compressed. The shape eases a stiff back without loading the abdomen. Keep the hands under the shoulders and the knees wide enough for comfort.
Side-lying rest
Lie on the side that is comfortable, with a cushion under the head and another between the knees so the top hip does not roll forward. A folded blanket at the belly can give a sense of boundary without pressure. This is a sensible rest late in pregnancy and a common place to recover the breath. Stay only as long as it feels quiet. Change sides if one shoulder complains.
Wide goddess stance
Stand with the feet wider than the hips, toes turned out a little, and bend the knees only as far as the belly stays free. Hands rest on the thighs. You are looking for leg strength without compression, not for a deep squat. Keep the breath moving. If the pelvis feels unstable, shorten the bend or hold a wall. The shape is finished when the legs have worked a little, not when the hips are lowest.
Open side stretch
Sit on a chair or a bolster, one hand on the thigh, and lean the other arm overhead only as far as the ribs lengthen without pulling on the belly. Keep both sitting bones down if you are on a seat. Breathe into the open side. The stretch gives the ribs room and eases a back that has been carrying a changing weight. Come up before the shoulder pinches, and do the other side with the same limit.
Supported squat
Hold a sturdy chair or the wall, feet a little wider than the hips, and bend the knees a short way. The belly stays free of the thighs. This is strength for standing up from a chair, not a pose to sink into. If the pelvic floor feels heavy, make the bend smaller or skip it. The support means you can come up without a lurch. Two or three slow bends are enough.
Seated breath
Sit tall on a chair or a bolster, one hand on the ribs and one on the thigh. Let the breath arrive and leave without a hold and without a special count. If counting makes you strain, drop the count. This is rehearsal of a breath you can use later, in a waiting room or at night, not a technique to master. Stop if you feel dizzy or short of air. Ordinary breathing is the point.
Wall rest
Sit on the floor or a chair with the back against a wall, knees bent, feet down. The wall does the work of staying upright so the belly is not asked to brace. Hands rest where they are comfortable. Use this when standing has been enough and lying down is awkward. A few quiet breaths here mark the end of effort. If the floor is impossible, the chair against the wall is the same rest.
