The short explanation
In the third trimester, gentle, regular activity is usually still helpful if your pregnancy is uncomplicated. Walking, pregnancy yoga led by a trained teacher, gentle stretching, stationary cycling, swimming where available, and pelvic floor exercises are commonly suggested. Pelvic tilts on hands and knees and sitting on a birthing ball can ease back discomfort. Aim for activity that leaves you able to talk comfortably. Avoid lying flat on your back for long, exercises with a risk of falling, heavy lifting, and anything that causes pain. Stop and rest if you feel dizzy, breathless or unwell.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Your doctor may advise limiting exercise if you have bleeding, a low placenta, high BP, signs of early labour or a short cervix.
- Balance changes as the bump grows, so use a wall or chair for support during standing exercises.
- Hot, humid weather makes overheating more likely; exercise in cooler parts of the day.
- Squatting and other positions taught in antenatal classes can help prepare for labour; ask whether your hospital runs classes.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you which exercises are suitable for your pregnancy. Your doctor can advise based on your health and history.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is it safe for me to exercise in the third trimester?
- Are there exercises I should avoid in my case?
- Does the hospital run antenatal classes or physiotherapy?
- Which symptoms during exercise mean I should stop?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department if you have chest pain, sudden breathlessness, fainting, vaginal bleeding or a gush of fluid during or after exercise.
Get help the same day
- Get care the same day if you notice regular painful tightenings or reduced baby movements.
Raise it at a routine appointment
- Ask about exercise at your routine antenatal visit.
