The benefits of exercising during pregnancy
The benefits of exercise during pregnancy are well documented. Numerous studies have proven it has a positive effect on both the expectant mum’s health and her baby’s health. That’s why we’re encouraging women to get Active for 2, whether that’s by going for a simple swim or a gentle jog.
Pregnancy exercise does much more than improve your well-being – it can support the development of your baby’s heart and brain too. If you’re struggling to find motivation, these facts about the benefits of pregnancy exercise may help get you started.
Why exercise in pregnancy?
The benefits of pregnancy exercise for mum
Pregnancy exercise can improve your experience of pregnancy in many ways. Studies show that exercising mothers:
- Experience less lower back pain1, pregnancy constipation8 and tiredness9.
- Are 30% less likely to develop gestational diabetes2.
- Are less likely to need an unplanned caesarean3,4.
- Experience fewer incidences5 and reduced severity6 of depression.

- Have reduced incidents of pregnancy constipation8.
- Experience less tiredness in pregnancy9.

The benefits of pregnancy exercise for baby
The benefits for your baby could last them a lifetime. Babies born to mothers who exercise in pregnancy are more likely to:
- Develop a healthier heart with a lower resting heart rate after birth11.
- Be born at what is considered a ‘normal’ birth weight, rather than overweight12.
- Be born with more mature brains and are quicker to develop neurologically13.
- Experience a reduced risk of respiratory distress at birth (if born to high-risk mothers)14.
Less maternal stress could also reduce the impact on the development of their immune system 15.
