Cause and effect

In plain English

If a pregnant woman who might develop high blood pressure exercises at a moderate pace, it won't make her baby smaller — so it's safe for the baby's growth.

See the scientific wording

Prenatal exercise at moderate intensity (3–6 METs) does not reduce infant birthweight in women at risk for hypertensive disorders, indicating that exercise in this range is safe for fetal growth and does not lead to intrauterine growth restriction.

What the research says

1 study

  1. Study: Exercise during pregnancy (frequency, intensity, type, time, volume): birth outcomes in women at risk of hypertensive disorders of pregnancy

    This study found that pregnant women at risk for high blood pressure who exercised moderately had babies with normal or even slightly higher birthweights — meaning exercise didn’t harm the baby’s growth. It’s safe and might even help!
