Walking During the Third Trimester of Pregnancy: Benefits, Routine, and Tips

Carlos Sánchez 8 min. of reading Women's Special Leave a comment

Maintaining an active lifestyle during pregnancy is one of the most widely recommended practices in both obstetric and sports science literature. Although the type and intensity of exercise should be adapted to each trimester, walking is one of the most accessible, safe, and beneficial activities a pregnant woman can perform throughout the nine months, especially during the final stage of pregnancy.

In this article, we’ll explain why walking during the third trimester of pregnancy is particularly valuable, how to structure a safe and progressive walking routine according to your week of pregnancy, and the benefits it offers both you and your baby.

Improves circulation

During the third trimester, blood volume increases significantly, and the uterus places greater pressure on the blood vessels in the pelvis. This can make venous return more difficult, increasing the likelihood of varicose veins, heavy legs, or a feeling of numbness.

Walking activates the calf muscle pump, the mechanism responsible for pushing blood back to the heart. A daily moderate-intensity walk is enough to stimulate this circulation and improve peripheral oxygenation, reducing the sensation of tired, heavy legs at the end of the day.

Reduces swelling

Swelling in the legs, ankles, and feet is one of the most common symptoms during the third trimester. It is caused by fluid retention and the pressure the baby places on the lymphatic and venous vessels in the pelvis.

Walking promotes lymphatic and venous drainage in the lower limbs, acting as a natural mechanical stimulus. There’s no need to walk for long periods—even a short but consistent daily walk can make a noticeable difference in reducing swelling throughout the day.

Relieves back pain

Lower back pain is one of the most common reasons for medical consultation during the third trimester. As the abdomen grows, the body’s center of gravity shifts forward, forcing the spinal muscles to work harder to maintain proper posture.

Walking, especially while maintaining an upright posture, activates the stabilizing muscles of the core and hips, helping to relieve accumulated tension in the lower back. In addition, the rhythmic movement encourages mobility in the sacroiliac joints, which are often a source of pain during this stage.

Improves digestion

Constipation and slow digestion are common symptoms during late pregnancy. Progesterone relaxes the smooth muscles of the digestive tract, slowing intestinal transit, while the growing uterus compresses the available space for the stomach and intestines.

The gentle movement produced by walking naturally stimulates intestinal peristalsis, helping regulate bowel movements and reduce gas accumulation. Taking a short walk after your main meals can be particularly effective in improving digestion without the need for supplements or medication.

Reduces stress and anxiety

As childbirth approaches, hormonal changes and the gradual adaptation to a new stage of life often lead to heightened psychological stress. Prenatal anxiety is common and, when not properly managed, can affect both maternal well-being and the baby’s development.

Walking outdoors stimulates the production of endorphins and serotonin, neurotransmitters that help reduce anxiety and regulate mood.

The repetitive rhythm of walking also has a meditative effect that helps clear the mind and reduce the body’s stress response. Even 20–30 minutes a day can have a measurable impact on emotional well-being.

Prepares the body for childbirth

Moderate, consistent physical activity during the third trimester helps maintain proper muscle tone in the muscle groups that play the greatest role during labor: the glutes, pelvic floor muscles, deep abdominal muscles, and quadriceps.

Walking strengthens these muscle groups in an integrated and functional way without placing excessive stress on the joints. In addition, maintaining good cardiovascular fitness helps manage the physical demands of contractions and contributes to a faster postpartum recovery.

Third Trimester Walking Routine

During the third trimester, pregnant women should gradually reduce both the duration and intensity of their walks. As the abdomen continues to grow, pressure on the back and joints increases, making it essential to prioritize comfort and listen to your body’s signals rather than focusing on performance goals.

Below is a suggested week-by-week walking plan:

Week of Pregnancy	Duration	Days	Guidelines
Weeks 25–28	30 min	Monday / Tuesday / Wednesday / Saturday / Sunday	5 min easy + 20 min moderate + 5 min easy
Weeks 29–32	25 min	Monday / Wednesday / Friday / Sunday	5 min easy + 15 min moderate + 5 min easy
Weeks 33–35	20 min	Monday / Wednesday / Friday / Sunday	5 min easy + 10 min moderate + 5 min easy
Weeks 36–37	15 min	Tuesday / Wednesday / Friday / Sunday	3 min easy + 9 min moderate + 3 min easy
Weeks 38–40	15 min	Tuesday / Thursday / Saturday	3 min easy + 9 min moderate + 3 min easy

Note: These guidelines are intended for general reference only. Always consult your doctor or midwife before starting or modifying any exercise routine during pregnancy.

Benefits of Walking During the Third Trimester for Your Baby

Moderate physical activity during pregnancy not only benefits the mother—it also has direct, positive effects on fetal development.

Improved oxygen supply: Moderate exercise increases maternal cardiac output and enhances gas exchange at the placental level, improving oxygen delivery to the fetus.
Optimal positioning: The rhythmic movement of walking may encourage the baby to adopt a head-down (cephalic) position, which is ideal for vaginal delivery.
Healthy development: Studies suggest that babies born to mothers who remain physically active during pregnancy have a lower risk of macrosomia (excessive birth weight) and better metabolic regulation during early childhood.
Sensory stimulation: The mother’s movement and increased heart rate act as sensory stimuli for the fetus, supporting healthy neurological development.
Lower risk of preterm birth: Regular, moderate exercise has been associated with a lower incidence of obstetric complications, including preterm birth, in low-risk pregnancies.

Tips for Walking Safely During the Third Trimester of Pregnancy

Walking is a low-impact activity, but during the third trimester it is important to follow a few precautions to ensure maximum safety.

Wear comfortable clothing and supportive footwear. Choose shoes with good cushioning and ankle support. Avoid high heels or very flat soles. Clothing should be breathable and allow freedom of movement.
Stay well hydrated. The risk of dehydration increases during pregnancy. Always carry water with you and drink before, during, and after your walk, even if you don’t feel thirsty.
Avoid walking during the hottest hours of the day. In summer or warm climates, schedule your walks early in the morning or in the evening. Overheating can be harmful to both mother and baby.
Rest whenever your body tells you to. Pay attention to warning signs such as shortness of breath, pelvic pressure, dizziness, or contractions. The goal is not to push your limits but to stay active safely and intelligently.
Consult your doctor or midwife. Before starting any exercise routine during pregnancy—and especially during the third trimester—it is essential to obtain approval from your healthcare provider. If you have a high-risk condition (placenta previa, gestational hypertension, or a multiple pregnancy), recommendations may differ significantly.

Walking during the third trimester of pregnancy is one of the simplest and most effective ways to support both the physical and emotional well-being of the mother during the final weeks before birth. Its benefits range from improved circulation and reduced swelling to better preparation for labor, enhanced emotional well-being, and optimal fetal development.

You don’t need special equipment or hours of training—a regular walking routine, adapted to each week of pregnancy and performed sensibly, is enough to make a real difference. Make it part of your daily routine and you’ll soon notice the benefits.
