Is walking safe during pregnancy?

Yes — walking is completely safe throughout all three trimesters and is one of the most recommended forms of exercise during pregnancy. The NHS encourages all pregnant women to stay active, and walking is explicitly cited as a suitable, low-risk way to do so. It requires no equipment, costs nothing, and can be adapted to your fitness level and how you are feeling on any given day.

Walking is ideal whether you were very active before pregnancy or are starting to exercise for the first time. It is gentle on the joints, carries no fall risk beyond everyday terrain, and can be sustained right up to your due date.

Benefits of walking during pregnancy

Regular walking during pregnancy provides a range of physical and mental benefits:

Cardiovascular health. Walking at a brisk pace raises the heart rate and improves cardiovascular fitness without high impact. Good cardiovascular fitness supports blood pressure regulation, reduces the risk of gestational diabetes, and increases energy levels.

Weight management. Healthy weight gain during pregnancy is beneficial for both mother and baby. Walking helps manage weight gain within recommended ranges without restrictive dieting.

Back pain prevention. Walking strengthens the muscles of the lower back, glutes, and legs, which helps support the changing posture and increased load of pregnancy. Many women find that regular walking reduces or prevents the back pain that is common in the second and third trimesters.

Mood and sleep. Physical activity triggers the release of endorphins, which improve mood and reduce anxiety. Regular walkers during pregnancy often report better sleep quality. Both mood and sleep are common challenges during pregnancy, making walking a practical, medication-free tool.

Reducing the risk of pregnancy complications. Regular moderate exercise including walking is associated with lower rates of gestational diabetes, pre-eclampsia, and excessive weight gain. The evidence for these benefits is well-established.

Preparation for labour. Walking in late pregnancy, particularly walking that involves hills or inclines, can encourage the baby into an optimal position for birth and is widely recommended by midwives in the final weeks.

The NHS recommends 150 minutes of moderate activity per week during pregnancy. Brisk walking — at a pace that slightly raises your breathing and heart rate but still allows you to hold a conversation — counts as moderate activity. This breaks down to around 30 minutes of brisk walking five days a week.

If you were very active before pregnancy, you may well walk more than this comfortably. If you were not particularly active, starting with shorter walks and building up gradually is the sensible approach.

Use the talk test: if you can hold a conversation while walking, you are at a suitable intensity. If you are too breathless to speak, slow down.

Adapting your walking as pregnancy progresses

First trimester

Walking can continue entirely as normal. You may find fatigue limits what feels manageable, particularly in early pregnancy. Listen to your body and rest when you need to.

Second trimester

Many women feel most energetic in the second trimester and this is a good time to establish a regular walking routine. The bump is growing but is not yet large enough to cause significant balance issues.

Third trimester

As the bump becomes large, walking pace may naturally slow and distances may shorten. This is completely normal and appropriate. You may notice:

  • Pelvic girdle pain (PGP): Pain in the pelvic area, particularly with steps or uneven surfaces. If you develop PGP, a physiotherapist can advise on stride length and technique to make walking more comfortable.
  • Braxton Hicks contractions: Mild, irregular tightening sensations that are a normal part of late pregnancy. They typically ease with rest and are not a reason to stop walking.
  • Swelling in the feet and ankles: Walking actually helps circulate fluid and can reduce swelling, but supportive footwear becomes more important.

Practical tips for walking in pregnancy

  • Footwear matters. As pregnancy progresses, ligaments loosen (due to the hormone relaxin) and feet may spread slightly. Wear supportive, well-fitting trainers or walking shoes. Avoid high heels entirely.
  • Stay hydrated. Carry water, especially in warm weather. Dehydration in pregnancy can trigger Braxton Hicks and contribute to dizziness.
  • Wear sunscreen. Pregnancy skin is more sensitive to UV radiation.
  • Choose safe terrain. In the third trimester, uneven surfaces and steep hills carry a slightly higher fall risk due to the shifted centre of gravity. Well-maintained paths are preferable.
  • Warm up and cool down. Start and end each walk at a gentle pace, particularly in cold weather.
  • Walk with company. Walking with a partner, friend, or antenatal group is motivating and adds a social dimension.

When to stop and seek advice

Stop walking and contact your midwife if you experience:

  • Chest pain or palpitations
  • Severe or unusual shortness of breath
  • Dizziness or light-headedness
  • Calf pain or significant swelling (can be a sign of DVT — seek urgent medical advice)
  • Any vaginal bleeding or fluid leakage
  • Regular painful contractions
  • Reduced fetal movement (contact your midwife immediately regardless of exercise)
