The short explanation
If your pregnancy is uncomplicated and you were already running regularly, many women can carry on running in pregnancy, usually at an easier pace and listening closely to their body. A common guide is to exercise at a level where you can still hold a conversation. As the bump grows, balance changes and joints loosen, so many women gradually move to walking, swimming, cycling on a stationary bike or pregnancy yoga. Staying active in pregnancy is linked to better fitness, mood and sleep, and lower chances of gestational diabetes. What matters is that you check with your doctor and stop if something feels wrong.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Some conditions mean exercise should be limited, such as bleeding, a low-lying placenta later in pregnancy, high BP, a short cervix or certain heart and lung problems.
- Avoid overheating, especially outdoors in Indian summers. Run in the cooler hours and drink water.
- Avoid activities with a risk of falling or being hit in the belly, and after the first trimester avoid lying flat on your back for long periods during exercise.
- Pelvic floor exercises are worth starting now too.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether running is suitable for your pregnancy. Your doctor can advise based on your history and how the pregnancy is going.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is it suitable for me to keep running?
- Are there any conditions in my pregnancy that limit exercise?
- When should I switch to lower-impact exercise?
- Which symptoms mean I should stop and get checked?
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, during or after exercise, you have chest pain, sudden breathlessness, fainting, vaginal bleeding or a gush of fluid.
Get help the same day
- Get care the same day if you have regular painful tightenings, calf pain and swelling, or reduced baby movements after exercise.
Raise it at a routine appointment
- Discuss your exercise routine at your next antenatal appointment.
