Can You Exercise While Pregnant?
Yes — exercise is not just safe but encouraged in a healthy pregnancy; aim for about 150 minutes of moderate activity a week.
The full answer
For most pregnancies, staying active is one of the best things you can do — it helps with mood, sleep, back pain, blood pressure, and preparing for birth, and it doesn't increase the risk of miscarriage. Health bodies such as ACOG and the NHS recommend about 150 minutes of moderate-intensity activity a week: brisk walking, swimming, stationary cycling, or prenatal yoga and light strength work all count. A good gauge is the 'talk test' — you should be able to hold a conversation while you move. What to adjust: avoid contact sports, activities with a fall risk (skiing, horse riding), scuba diving, and — after the first trimester — exercises lying flat on your back. Stay hydrated, don't overheat, and stop if you have pain, bleeding, dizziness, or contractions.
How to exercise safely
- Aim for ~150 min/week of moderate activity (walking, swimming, prenatal yoga)
- Use the 'talk test' — you should be able to chat while moving
- Avoid contact sports, fall risks, scuba diving, and lying flat on your back after the 1st trimester
When to avoid: Stop and call your provider for pain, bleeding, leaking fluid, dizziness, chest pain, or regular contractions.
Exercise by trimester
| Stage | What changes |
|---|---|
| First trimester | Exercise is actively encouraged in an uncomplicated pregnancy. If you were active before, you can generally continue; if you weren't, this is a reasonable time to start gently rather than a reason not to. |
| Second trimester | Often the most comfortable period for activity. Balance changes as your centre of gravity shifts, which is worth accounting for in what you choose rather than a reason to stop. |
| Third trimester | Still encouraged, with adjustments — lower impact, less time flat on your back, and stopping when something hurts rather than pushing through. |
Common questions about exercise in pregnancy
How much exercise is recommended in pregnancy?
Guidance commonly suggests around 150 minutes of moderate activity a week in an uncomplicated pregnancy — the same figure as for adults generally. Walking, swimming, stationary cycling and prenatal classes are the usual suggestions.
What should I avoid?
Contact sports, activities with a meaningful fall risk, scuba diving, and exercising in heat. Lying flat on your back for long periods is usually discouraged later on. If you have pregnancy complications, your provider's advice takes precedence over any general list.
When should I stop and call someone?
Bleeding, regular painful contractions, fluid leaking, chest pain, severe breathlessness or dizziness are all reasons to stop and contact your provider rather than finish the session.
Staying safe and active in pregnancy
Most “can I do this?” questions in pregnancy come down to three things. Overheating — anything that pushes your core temperature above about 102°F (39°C), like hot tubs, saunas, and very hot baths — is best avoided, especially in the first trimester. Impact and balance — falls, contact sports, and jarring, high-force rides are the reason some activities are off-limits later on. And infection or absorption — the reason tattoos and some treatments call for caution. Set against that, movement is actively encouraged: about 150 minutes of moderate activity a week is recommended in a healthy pregnancy. When in doubt about your situation, your midwife or provider is the final word.
