Is yoga safe during pregnancy?

Yes — yoga is one of the most suitable forms of exercise during pregnancy and is actively recommended by many midwives and health professionals. It combines gentle movement, breathing techniques, and relaxation in a way that is well-suited to the physical and emotional demands of pregnancy. The NHS encourages pregnant women to stay active, and yoga is frequently cited as an ideal way to do so.

Prenatal yoga classes are specifically designed for expectant mothers. If you have never done yoga before, starting with a dedicated prenatal class is the best approach. If you are an experienced practitioner, you can continue with your regular practice provided you make certain modifications, particularly as your pregnancy progresses.

Benefits of yoga in pregnancy

Yoga offers a range of specific benefits during pregnancy:

  • Flexibility and mobility — helps manage the physical changes in your body, particularly as the pelvis and hips shift to accommodate your growing baby
  • Pelvic floor strength — many yoga poses engage and strengthen the pelvic floor, which supports the uterus, bladder, and bowel, and aids recovery after birth
  • Breathing techniques — the controlled breathing practised in yoga has direct applications in labour, helping manage contractions and stay calm
  • Stress and anxiety — yoga’s mindful, meditative elements are particularly valuable during pregnancy, when anxiety and disrupted sleep are common
  • Back pain relief — gentle stretching and strengthening of the back and core can reduce the lower back pain that affects many women in the second and third trimesters
  • Community — prenatal yoga classes are a good way to meet other pregnant women at a similar stage

First trimester

During the first trimester, most yoga poses are safe and you can continue your regular practice largely as normal. Fatigue is common in early pregnancy, so listen to your body and do not push through exhaustion.

The main thing to avoid in the first trimester is hot yoga (Bikram yoga). Overheating during early pregnancy — particularly in the first trimester when the baby’s neural tube is developing — carries risks. Any heated yoga studio or any practice that causes you to sweat heavily should be avoided throughout pregnancy.

Second trimester

The second trimester is often when yoga feels most comfortable — fatigue typically eases and the bump is not yet large enough to restrict movement significantly. This is also the time to start modifying your practice more intentionally.

From around 16–20 weeks, avoid lying flat on your back for extended periods. In this position, the weight of the growing uterus can press on the inferior vena cava — the large vein that returns blood to your heart — which may reduce circulation and cause dizziness or light-headedness. Most yoga teachers will automatically guide you to roll onto your side rather than lying flat in savasana.

Deep twists that compress the abdomen should also be avoided from the second trimester. Open twists — where you twist away from the front body rather than compressing it — are generally fine and feel good on the spine.

Third trimester

In the third trimester, your centre of gravity has shifted significantly and balance becomes less reliable. This makes poses requiring balance on one leg — such as warrior III or tree pose — worth approaching with a wall or chair for support. Your bump will also physically limit some forward folds.

Beneficial poses in late pregnancy include cat-cow (for back pain relief), supported wide-leg forward fold, pigeon pose (hip opening), and reclined cobbler pose (baddha konasana) supported on bolsters or folded blankets.

Inversions — including shoulder stands and headstands — should be avoided unless you are very experienced and your midwife has no concerns, as the risk of falls outweighs the benefit.

Poses and practices to avoid

  • Hot yoga / Bikram yoga — overheating risk throughout all three trimesters
  • Deep abdominal twists — compress the uterus; use open twists instead
  • Lying flat on the back — avoid from around 16–20 weeks
  • Strong inversions (headstand, shoulder stand) — fall risk and blood pressure effects
  • Deep backbends — put strain on the abdominal muscles and linea alba
  • Breath retention (kumbhaka) — prolonged breath holding reduces oxygen supply; breathe continuously

When to stop and seek advice

Stop your practice and contact your midwife if you experience:

  • Pain in your abdomen, pelvis, or chest
  • Dizziness, light-headedness, or feeling faint
  • Shortness of breath that feels out of proportion to the effort
  • Any vaginal bleeding or fluid leakage
  • Decreased baby movement (contact your midwife immediately)
  • Sudden swelling of the face, hands, or feet

Starting yoga in pregnancy

If you have never done yoga before, pregnancy is actually a good time to start — prenatal classes are taught with first-timers in mind and the pace is designed to be accessible. Look for classes specifically advertised as prenatal yoga, as teachers will have appropriate training and will know how to support you. Many leisure centres, yoga studios, and online platforms offer dedicated prenatal classes.

Always let your yoga teacher know you are pregnant and how far along you are before the class begins.
