Further information

Exercise during pregnancy is important for your health and that of your baby. In fact, there is some evidence that active women are less likely to experience problems in later pregnancy and labour. But what sort of excercises are best when you are pregnant, and are there any types you should avoid?

Become an NCT member and find other pregnant women in your local area to exercise with. It could be fun.

Cardio exercise during pregnancy

Cardiovascular exercise is activity such as walking or swimming which raises the heart rate. It will benefit both you and your baby as it:

  • improves your efficiency in transporting and utilising oxygen,
  • reduces the likelihood of developing circulatory problems, such as cramps or varicose veins,
  • improves blood flow to the placenta and
  • reduces the risks of gestational diabetes and high blood pressure.

Cardiovascular exercise also increases your energy levels, can improve your sleep patterns and, importantly for many women looking to do exercise in pregnancy, can control additional weight gain.


Walking is a great way to improve aerobic fitness and help tone your legs. It is easy to incorporate into your day - get off the bus one stop earlier, park the car further away, or take the stairs rather than the lift – just walk!

Your ankles are more vulnerable to twisting during exercise in pregnancy so make sure you have the correct footwear for the terrain you’re walking on. Flat shoes for work will help you incorporate walking into your daily routine. If walking in the country use walking boots or waterproof trainers, as wellies do not provide sufficient ankle support.

A good heel/toe action is essential to absorb shock through the foot, and try to keep the legs aligned in front rather than turning out. Walk tall with shoulders down and head up and don’t forget to use your abdominal muscles to draw your baby in.

A good supportive bra is important to reduce breast movement, particularly if you’re walking briskly. As your pregnancy progresses, you will naturally reduce the pace to maintain comfort. Walking is a suitably low impact exercise that can help you to stay fit and healthy.

Running and aerobic exercise

If you ran regularly before pregnancy, you should be able to continue to run while you're pregnant, with no adverse effects for you or your baby. If you didn't run regularly before, pregnancy is probably not the best time to start.

If you do an aerobic exercise programme (such as running, cycling or aerobics classes), tell the instructor that you're pregnant so they can adjust and suggest suitable work-outs as your pregnancy progresses.

Generally, towards the end of your pregnancy, you should be aiming to gradually reduce your overall activity. Your healthcare professional or instructor can give you guidance on when and how to reduce your exercise.

Swimming in pregnancy

Exercising in water supports your bump and is great for your circulation as the pressure of the water on your blood vessels stimulates blood flow and reduces any swelling. It’s also an excellent way to maintain your abdominal tone. Take care not to overwork these muscles with strong rotational movements, particularly in deeper water.

"Gentle swimming can be particularly relaxing but if you are experiencing any pelvic girdle pain you should avoid breaststroke leg action."

Avoid butterfly stroke as this encourages large spinal movements. Invest in a pair of goggles so you can swim with your head down – swimming with your head lifted out of the water will cause your hips to drop and accentuate the increased curve in the lumbar spine.

You don’t have to be a swimmer to enjoy the benefits of water – contact your local pool to find out about water based classes with pregnancy exercises included.

Weight training exercise in pregnancy

As pregnancy progresses, your body undergoes its own weight training. Your legs will naturally strengthen with the increased weight and your spinal muscles will tighten to keep your body upright.

Your arms, however, may not be similarly challenged, especially if your partner insists you don’t do any lifting. Yet as soon as your baby arrives, you will be required to lift, carry and hold her for many hours and even a little seven pound baby will start to feel heavy! So do lift the lighter shopping bags and politely decline the offer of a hand up from the sofa so that your arms get some work, but ensure you do so with the abdominal muscles held in.

Tummy and pelvic floor exercises

The abdominal (stomach) muscles undergo an enormous amount of stretching during pregnancy, weakening your spinal support mechanism and causing low back pain. It is vital that these muscles are used when bending, lifting and carrying; they should also be activated regularly throughout the day to help maintain a degree of abdominal tone. This will also help you regain a flat tummy postnatally. Sit ups should not be performed after the first three months as this will stress the muscles further and delay postnatal repair.

This exercise can be done in any position – sitting, standing or kneeling on hands/knees.

  • Draw your tummy in towards your spine
  • Hold for a few seconds, continuing to breathe
  • Release gently
  • Repeat as frequently as possible throughout the day
  • Incorporate this when you bend or lift to keep your back supported
  • This should be a soft sinking feeling, rather than a strong bracing action and the breath should not be held.

It is also essential to exercise the pelvic floor muscles regularly.

Yoga and pilates in pregnancy

Pregnancy is the perfect time to get in touch with your body and there’s no better way to do so than with a mind/body workout such as yoga or pilates. Check the instructor is qualified to teach pregnant women or, better still, attend a pregnancy-specific class. If you do yoga or pilates at home, make sure the exercises you do are safe for pregnancy.

Such classes aim to improve posture through stretching and strengthening exercises which should help to reduce pregnancy aches and pains. However, do be careful not to overstretch.

Yoga and meditation may help you to relax – deep breathing and relaxation techniques are essential tools to help you de-stress and will be invaluable during labour. Pilates is particularly good for strengthening the deep abdominal and pelvic floor muscles.

If you prefer a gentler mind/body exercise, you may find yoga breathing and relaxation exercises very helpful – and this will also help prepare you for labour.
