Studies from institutions such as the Universidad Politécnica de Madrid and the Universidad de Granada suggest that moderate training programs, including aerobic exercise and stretching, can reduce the risk of fetal macrosomia by half and decrease the likelihood of cesarean sections by 21%. Swimming is noted as a particularly effective aquatic exercise because buoyancy helps alleviate weight-related pressure on the back and legs while improving cardiorespiratory health. Further recommendations from the World Health Organization and the Ministry of Health suggest aiming for at least 150 minutes of moderate activity per week. Experts note that when medically cleared, exercise can help prevent gestational diabetes and arterial hypertension, reduce swelling and nausea, and support mental health by lowering the risk of anxiety and postpartum depression. ## Timeline ### 2026-10-09: Physical exercise benefits for pregnant women Medical experts and health organizations recommend at least 150 minutes of moderate, low-impact exercise per week during pregnancy to reduce risks like gestational diabetes and improve maternal well-being. 2 sources. https://clstr.news/cluster/physical-exercise-benefits-for-pregnant-women ### 2026-09-19: Prenatal exercise and swimming benefits for maternal health Moderate prenatal exercise, including swimming, can reduce the risk of cesarean sections, prevent fetal macrosomia, and improve maternal physical comfort and cardiorespiratory health. 2 sources. https://clstr.news/cluster/prenatal-exercise-and-swimming-benefits-for-maternal-health --- Cite as: Health benefits of prenatal physical exercise.
