Now that you’re pregnant you might be looking forward to indulging in more of your favourite food and relaxing without worrying about fitting into your skinniest jeans. However, it’s important to maintain a healthy diet and to stick to an exercise routine to keep you feeling fit and healthy during your pregnancy.

Exercising during pregnancy will ensure you stay fit and healthy, as well as helping you deal with stress (which there is a lot of during pregnancy!). If you're nervous about exercising while pregnant, we fill you in on absolutely everything you need to know from the dos and don'ts of how to exercise safely, the best exercises to keep you in shape, where you can find them and even what you should wear!

Is exercise during pregnancy safe?

There are several myths around exercise during pregnancy and many women wrongly believe that it is unsafe. However, exercise is not dangerous for you or your baby as long as you do it safely and know your body’s limits. Exercise is actually recommended as it can be incredibly beneficial for mums-to-be.

Staying active during pregnancy can mean you are less likely to experience complications or issues in later pregnancy. The NHS recommends exercising throughout pregnancy to help you adapt to your changing shape and weight gain. To exercise safely, it is important not to over exert yourself. The NHS guidelines explain that 'As a general rule, you should be able to hold a conversation as you exercise. If you become breathless as you talk, then you're probably exercising too strenuously'.

How often should you exercise during pregnancy?

The NHS recommends 'beginning with no more than 15 minutes of continuous exercise, three times a week. Increase this gradually to at least four 30-minute sessions a week'. In order to keep up short but regular bouts of exercise while pregnant, it is a good idea to find something that you enjoy as you'll be more likely to stick it out! If you've lost your fitness mojo then try switching things up or exercising with a friend.

Inactivity is bad for your health whether you are pregnant or not. So, although pregnancy seems like the perfect reason to put your feet up *all the time*, (putting your feet up some of the time is still recommended, as it is great for swelling) it is a good idea to aim for 30 minutes of moderate intensity activity most days of the week. You can break it down into small ten or five minute sessions if that suits you!

What are the benefits of exercising during pregnancy?

There are several benefits of exercising during pregnancy. Exercise could help your body snap back to its pre-baby shape, is thought to be good for your baby and may make your labour easier. It can help you both mentally and physically during this crucial and life-changing time. Plus, it can even combat certain pregnancy-related health issues.

Your body goes through many physical and hormonal changes during pregnancy, which can come with a number of health problems. The international healthcare group Bupa stress the importance of exercising while pregnant as 'regular exercise can help to relieve some of these pregnancy-related niggles.'

‘Even a modest amount of exercise during pregnancy will release those feel-good endorphins, lift your mood and make it easier to sleep, reducing stress, anxiety and depression,’ says Bump2Mum fitness expert Lucie Brand

12 benefits of exercise during pregnancy:

1) Reduces tiredness and improves sleep

You might feel that exercise is the last thing on your mind during pregnancy if you're feeling tired and sluggish. However, regular exercise can increase your energy levels, make you feel less tired in the long run and even improve your sleep.  

'Even a single 15-minute walk can give you an energy boost, and the benefits increase with more frequent physical activity' according to the NHS.

2) Eases back pain

Many pregnant woman experience back pain during pregnancy. Low impact exercise such as yoga and workouts underwater in a swimming pool can help to relieve it.

3) Helps with constipation

Pregnant women often suffer from constipation due to the hormone progesterone and the strain of your growing bump. Light exercise, along with a healthy pregnancy diet can aid your digestion.

Exercise shortens the time it takes for food to pass through the large intestine meaning you get less backed up. It also speeds up your breathing and heart rate which can stimulate the natural squeezing of muscles in your intestines which means you will find it easier when you do go to the loo.

4) Improves your mood

Exercise is a great way to improve your mood. If you exercise regularly, you are less likely to suffer from depression or anxiety or your symptoms could be lessened. Aerobic exercise such as walking, cycling and running are often found to give a post-workout high. Exercising outside has even more mood enhancing benefits because it helps with your natural body clock which can have an impact on your mood.

Better Health suggests the possible scientific reasons behind the way exercise enhances mood:
  • 'Exercise helps chronic depression by increasing serotonin (which helps your brain regulate mood, sleep and appetite) or brain-derived neurotrophic factor (which helps neurons to grow).
    Exercise reduces immune system chemicals that can make depression worse.
    Exercise increases your level of endorphins, which are natural mood lifters.
    Exercise helps by getting your sleep patterns back to normal. We know getting enough sleep can protect the brain from damage.
    Exercise gives you a focused activity that can help you feel a sense of accomplishment. 
    Exercise limits the effect of stress on your brain.'

5) Lower gestational diabetes risk

Whenever you eat, your body produces the hormone insulin, which regulates your blood sugar. During pregnancy, your body needs extra insulin and if you don’t produce enough, your blood sugar levels can become abnormally high – and this is known as gestational diabetes, which can only be developed when pregnant. Gestational diabetes increases the likelihood of problems, such as high blood pressure or pre-eclampsia.

However, if you exercise during pregnancy you can lower your 'gestational diabetes risk by as much as 27 percent according to Parents. Many healthy and fit women develop gestational diabetes because age and genetics are strong factors but exercise can still help to prevent or delay the need for extra insulin or medication.

10) Limits the risk of pre and postnatal depression

We know exercise can increase your mood so it is logical that it can also lessen the risk of depression during and after pregnancy. Again, exercising outdoors is even better because bright light has antidepressant effects.

12) Helps with high blood pressure

If you're pregnant and have a history of high blood pressure (hypertension), or have developed high blood pressure for the first time in pregnancy then it will need to be managed to prevent complications such as pre-eclampsia. Pregnant women with high blood pressure will often be required to attend hospital for more check-ups and tests.

High blood pressure is often linked with general inactivity. Therefore, increasing your activity levels through gentle exercise could help to reduce your blood pressure naturally.

What are the dos and don'ts of pregnancy exercise?

As we've said, it is important that when you do exercise, you do it safely. If you are worried about what you can and can’t add to your pregnancy exercise routine then we're here to help. Take note of our dos and don’ts so you know the right way to stay fit and healthy.

What are the best exercises for pregnancy?

When looking for the ideal pregnancy workout there are a few factors to consider. Exercise that gets your heart pumping and improves flexibility and mobility without causing physical stress is perfect. For best results, try and do a combination of aerobic exercise and muscle-strengthening exercise. 

Running, walking, dancing, swimming, weight-training, cycling, pilates, aerobics and yoga (on land or in a swimming pool) are all fantastic and totally safe exercises to do with a bump. Exercise doesn't have to be traditional - it is also a good idea to make yourself more active in general daily life. Try going for short walks (perhaps with your pooch!), taking the stairs, housework and gardening.

If you prefer exercising at home, where you can sing along to the music, get as sweaty as you want and not have to worry about getting to the gym, then a pregnancy exercise DVD might be for you. There are specialised online workout platforms like Results with a Bump, a franchise of Results with Lucy (Created by TOWIE star, Lucy Mecklenburgh) designed to help you reach your pregnancy fitness goals. Pregnancy workouts on YouTube are another great way to keep fit in the comfort of your own home, and now we’ve all got smartphones, tablets, and smart TVs, it is easier than ever to stream and watch straight away.

There are some great bloggers and influencers out there who post pregnancy-safe workouts and motivational guides to sticking to an exercise routine while pregnant. Kayla Itsines has a great guide to exercise while pregnant, including a varied workout including squats, tricep dips and donkey kicks. 

Instagram influencer Simone De La Rue (@bodybysimone) has recently released a fitness DVD with pregnant Made In Chelsea star Millie Mackintosh and has loads of great tips on her Instagram feed, too.

What exercise should you avoid during pregnancy?

Adrenaline junkies it’s time to go back to basics, for nine months at least! It is a good idea to avoid high-risk activities or contact sports (where you could injure yourself, could be in danger of falling or could hit your bump) such as squash, gymnastics, ice-skating, rollerblading or horse riding. It is also a good idea to avoid exercises that involve you lying on your front after the first trimester and avoid lying on your back after 12 weeks.

If you have a personal trainer or are part of a sports team it’s best to ensure they are aware of your pregnancy as soon as possible. This way you can work with your trainer to develop a new regime designed to work with your pregnancy, ensuring you aren’t doing anything that is unsafe for you and your baby. Before starting any new exercise or if you are unsure whether you can keep up your fave hobby, it is a good idea to consult a doctor, midwife or physiotherapist.

Can I still work out in the gym when pregnant?

If the gym’s your thing and you want to carry on with a bump, it’s totally do-able. It’s just a case of making tweaks, building up gradually and getting advice. Simply take advantage of the professionals at your gym, be workout smart and extend your cool down to stay safe.

Another good option at the gym is pregnancy exercise classes. Pounding the treadmill isn’t everyone’s cup of tea, which is why doing fun and sociable maternity exercise classes can be the perfect option. There are plenty of pregnancy-specific classes that are suitable for mums-to-be which still give you the workout your changing body needs. Just make sure that ask your instructor any questions you have about the class and you make them aware of any health issues, so they can safely tailor your workout.  

What exercises prepare you for labour and being a new mum?

Pregnancy exercises: Leg lifts

When deciding on what exercises to do during pregnancy, a good way to start is to focus your efforts on exercises that will strengthen the muscles you need during labour and for when you are a new mum. You need strong abs for the birth, powerful legs and core to help you carry the extra pregnancy weight and a toned back and arms to ease the strain of regularly lifting your new one when they are born! Focus on simple repeated exercises and relaxing stretches that will help you strengthen your muscles, improve flexibility and balance.

Should I do pelvic floor exercises when pregnant?

As a mum-to-be, you'll probably have heard all about pelvic floor muscles, but you may not know that working on them can help ease problems during as well as after your pregnancy.

Made up of muscles and tissue, your pelvic floor can stretch under a lot of weight and spring back up again. ‘Visualise a hammock of muscles running from your pubic bone, back between your legs and into the bottom of your spine,’ says pregnancy fitness specialist Alison Merry.

During pregnancy, the muscles and tissues can become exhausted with all the effort of bearing weight for so long and can prolapse – which is why certain exercises can help strengthen the area before your baby arrives. These exercises will also keep the entire area strong and help prevent against possible incontinence problems after you’ve given birth.

You can do simple squeezing or clenching, sometimes known as Kegel exercises, or pelvic tilts to prepare you for labour and beyond. Or try using a pelvic floor exerciser designed to help you regain some strength and control down there!

Are there fitness apps for mums I can use?

Most mums find maintaining a work-life balance hard enough as it is, let alone trying to fit a complicated (and expensive) exercise regime into an already jam-packed week. So forget rushing to make it to your gym class and try the fitness apps specially designed for mums so they can work out at home. There are loads of free pregnancy apps with weekly workouts, tailored videos and strengthening exercises to guide you with no fuss and no cost! 

What should I wear when exercising while pregnant?

Once you’ve decided to soldier on with pregnancy exercise, the last thing you need is to find none of your regular gym clothes fit. Rest assured maternity activewear can be just as stylish as your current sweaty betty get-up. You can even get specialised pregnancy gym gear, like support belts for your back and bump, to keep you safe and comfortable during exercise. To prove it, we’ve compiled a list of the best maternity gym clothes on the market to help you stay active during pregnancy.
