Prenatal yoga: what’s safe in each trimester

Before you start

Check with your obstetrician or midwife before starting or continuing yoga in pregnancy, especially if you have a high-risk pregnancy, placenta problems, high blood pressure, or a history of preterm labour. Medical guidance (for example from the American College of Obstetricians and Gynecologists) supports regular moderate activity in an uncomplicated pregnancy — about 150 minutes a week — with modified yoga among the suitable options.

First trimester (weeks 1–13)

• Focus on breath, gentle mobility and posture; tiredness and nausea are common, so keep sessions flexible.
• Avoid overheating — no hot yoga.
• Skip strong core work, deep twists through the belly and any pose that compresses the abdomen.

Second trimester (weeks 14–27)

• Often the most comfortable time to practise: hip openers, gentle strength for legs and back, supported squats and pelvic-floor awareness.
• Avoid lying flat on your back for long periods as the bump grows — use an incline or side-lying instead.
• Use a wall or chair for balance poses; your centre of gravity is changing.

Third trimester (weeks 28–40)

• Shift to comfort: breathing for labour, gentle pelvic movement, supported rest.
• Avoid overstretching — pregnancy hormones loosen ligaments, so stop at a comfortable range.
• No inversions or jumping; take more breaks.

Stop and call your doctor if you notice

• Vaginal bleeding or fluid leaking.
• Regular, painful contractions.
• Chest pain, breathlessness before exertion, dizziness or a severe headache.
• Calf pain or swelling, or muscle weakness affecting balance.

After birth

Postnatal yoga usually begins with breath, pelvic-floor and gentle core recovery once your doctor clears you (often around 6 weeks, longer after a caesarean). Progress gradually, especially if you have abdominal separation.
