Prenatal Yoga

Prenatal yoga is yoga adapted for pregnancy: slower, well supported, and built around poses and breathing that make room for a growing belly and a shifting sense of balance. Many expectant mothers use it to stay active, to ease everyday aches and to practice calm, steady breathing before birth. This article covers the basics. It isn't medical advice, so talk to your own ob-gyn or midwife before you start.

Is yoga safe during pregnancy?

For most people, yes. The American College of Obstetricians and Gynecologists (ACOG) says that if you're healthy and your pregnancy is normal, it's safe to continue or start regular physical activity, and that exercise doesn't increase the risk of miscarriage, low birth weight or early delivery. ACOG lists modified yoga among the activities it considers good choices, and points to prenatal classes that teach modified poses.

Some conditions mean you shouldn't exercise, or should only do so with close guidance. ACOG's guidance for doctors lists, for example, some heart and lung conditions, placenta previa later in pregnancy, preeclampsia, ruptured membranes and signs of preterm labor. That's why the first step is always a conversation with your ob-gyn.

What ACOG says may help

According to ACOG, regular exercise in pregnancy can:

• Reduce back pain
• Ease constipation
• Possibly lower the risk of gestational diabetes, preeclampsia and cesarean birth
• Support healthy weight gain
• Improve overall fitness and heart health
• Help you lose the baby weight after birth

ACOG suggests aiming for about 150 minutes of moderate activity a week, which you can split into shorter sessions. A prenatal yoga class can be part of that, along with walking or swimming.

What to avoid

• Hot yoga and hot Pilates. ACOG and the US National Center for Complementary and Integrative Health both advise against them in pregnancy because of the risk of overheating. Avoid getting overheated generally, especially in the first trimester, and drink plenty of water.
• Lying flat on your back or standing still for long periods. ACOG explains that lying on your back lets your uterus press on a large vein that returns blood to your heart. Prenatal teachers usually prop you up on a bolster or have you lie on your side instead.
• Poses that risk a fall or strain your belly. ACOG lists activities that may cause a fall among those to avoid. Most prenatal teachers also skip deep twists and backbends, strong core work and inversions unless your teacher and doctor say otherwise, and use a wall or chair for balance poses.
• Pushing past comfort. Listen to your body and ease off well before your limit.

Stop and call your doctor if you notice

ACOG lists these warning signs: bleeding from the vagina, feeling dizzy or faint, shortness of breath before you start exercising, chest pain, headache, muscle weakness, calf pain or swelling, regular painful contractions, or fluid gushing or leaking from the vagina.

Gentle poses a prenatal teacher may use

These are common in prenatal classes. Learn them with a qualified prenatal teacher who can adapt them for your stage of pregnancy.

• Bound angle (baddha konasana). Sitting with the soles of the feet together, often against a wall or on a cushion. It gently stretches the inner thighs and is a comfortable base for breathing practice.
• Supported squat. A wide squat with a block or bolster under the hips. Teachers use it to help you get used to opening and relaxing the pelvic floor.
• Gentle seated side stretch. Reaching one arm overhead and leaning to the side to lengthen the side body, with an open twist (turning away from the belly) only if comfortable.
• Supported triangle (trikonasana). With a short stance and a hand on a block or chair, it stretches the legs and side body while keeping you stable.
• Supported reclining goddess. Lying back on a slanted bolster with the soles of the feet together and the knees supported. Many people find it restful, and the incline keeps you off a flat back.

Finding a class or retreat

Look for a teacher with specific prenatal training, and tell them how far along you are. A gentle or restorative yoga class can be a good alternative. If you're thinking of a yoga trip while pregnant, check with your doctor first, choose a calm retreat without heated classes, and ask about the nearest hospital.

Frequently asked questions

Can I start yoga for the first time while pregnant?

ACOG says healthy people with a normal pregnancy can start regular physical activity. Choose a prenatal class designed for beginners and check with your ob-gyn first.

Is hot yoga safe during pregnancy?

No. ACOG and NCCIH both advise avoiding hot yoga in pregnancy because it can cause overheating.

Can I lie on my back in yoga while pregnant?

ACOG advises avoiding lying flat on your back as much as possible, because your uterus can press on a large vein that returns blood to your heart. Use a bolster to recline or lie on your side.

What are the signs I should stop exercising?

Stop and call your doctor if you have vaginal bleeding, dizziness, chest pain, a headache, calf pain or swelling, regular painful contractions or leaking fluid, among other signs ACOG lists.
