Prenatal Exercise Do's & Dont's

Emily Andrew • December 27, 2020

You're pregnant! Congratulations!

Suddenly you're faced with loads of rules on what you can and can't do. From foods to avoid to vitamins to take, it's easy to get totally overwhelmed.



When I first found out I was pregnant I suddenly began to question everything - Am I doing this right? Should I even be doing that? What is normal to feel? HOW IS IT POSSIBLE TO FEEL SO RUBBISH?!



The list goes on and on...



Some women will breeze through pregnancy and others won't. We're all built differently and just because you're struggling doesn't mean you're doing anything wrong but it's really important to be kind to yourself.



For the first 11 weeks I suffered with horrific "morning" sickness -whoever coined it that needs to seriously reconsider the name! I also had really bad back pain down the left side of my body coupled with what felt like horrendous period pains. Needless to say, the last thing that I wanted to do was exercise!



However, with movement being the main part of my job I had to continue to teach so I made sure to pay attention to anything that really didn't help my symptoms and amended or avoided them. It can be pretty frustrating if you consider yourself quite an active person but in the long run, you'll thank yourself for giving yourself a break!



It's also key to really think about what your exercise routine looked like before you were pregnant. If you are a seasoned runner you don't have to hang up your trainers the minute you find out you're expecting. Whilst pregnancy may not be the time to take up HIIT training if you've never done it before, it doesn't mean you have to stop doing the things you already do and love.



If you haven't had a regular exercise routine for a while then start small with a 30 minute daily walk, swimming or look for low impact prenatal classes such as Pilates.



To help you give you a clear idea of what you should and shouldn't be doing when it comes to exercising whilst pregnant I've come up with a handy list of prenatal do's and don'ts.



Listen to your body

This is something that I always advocate for, whether you're pregnant or not. However, it's even more important from the moment that you find you're expecting to really pay attention to what your body is trying to tell you.


Because of all the changes your body goes through you may feel a heightened sense of sensations and be more alert to every move you make and breath you take. This is totally normal and it's important not to let yourself get too stressed by questioning everything you feel. That being said if some days you are feeling lethargic and achy it's probably best not to push yourself through a rigorous workout, instead opt for a nice low impact/stretchy session or just skip it all together!



Don't overstretch

During pregnancy your body is flooded with a hormone called Relaxin which is key for aiding implantation, placenta growth as well as stopping contractions as the baby grows to prevent early delivery. Later on in pregnancy relaxin also helps the ligaments in the pelvis to stretch ready for labour.



A side effect of all this much needed Relaxin is that other muscles will also start to be effected so you may find that your flexibility is increased.



"Great!" I hear you cry... "Maybe I can realise my childhood dream of doing the splits!"



Actually, it's really important not to overstretch and encourage this as you could start to develop instability in joints and areas of the body.




Your hips, for example are a key area of the body that needs strengthening to remain stable and supportive throughout pregnancy so movements like Clam Shells are going to be key for you to support your changing body.



Support your balance

Over the course of your pregnancy your center of gravity will change as your bump grows, so it's important to keep that in mind whenever you're exercising. When you do any standing work it's handy to have a chair close by to support you just in case you find you're suddenly more wobbly than you used to be!



If you don't have a chair you can use then the kitchen counter or even a wall will suffice!




Needless to say, as your balance is challenged it's also a good idea to avoid contact sports or any exercise that has a high risk of falling or someone else falling into you.



Limit your ab work

During the first trimester (1-12 weeks) start to limit the amount of "sit up" abdominal exercises needs to be reduced. After week 12 and into your second and third trimester it's important to avoid any "sit up" or "crunching" movements as the linea alba (a fibrous structure that runs down the middle of your abdomen) naturally separates and shouldn't be put under any added pressure as this can cause diastasis recti.



Instead, focus on the lifting of the belly & pelvic floor (like you're hugging your baby from underneath).



Get off your back

After 16 weeks avoid lying on your back for a long time as not only will it most likely feel uncomfortable it can also cause bloodflow issues to your baby.



Instead, play it safe and prop yourself up on your elbows or use pillows to adjust any supine work you do.



Avoid having both legs in the air

This can put too much pressure on your back and core. Movements like double leg stretch and the hundred will need to be adjusted so that you only have one leg in the air at a time. If you're unsure of adjustments at any point then you can always ask your teacher who should be able to give you suitable alternatives throughout your pregnancy.



Kneel instead of lying on your front

If you found out you were pregnant later on in your first trimester don't worry if you've still been doing movements lying on your front but it's good to start to avoid them as soon as you know you're pregnant.



Movements like swimming can still be done by kneeling slightly at an angle so use this as an alternative where appropriate.



Plank no more

It all comes back to abdominal pressure, from your second trimester full planks (including elbow planks) can put too much pressure on your back and abs. Instead, opt for a hover plank which will help to support both your back and abs but still gives you a whole body challenge.



Stay hydrated

Whenever you're exercising it's important to keep your body hydrated, so take breaks when you need to and if you feel lightheaded or dizzy -stop. In general you should always be keeping yourself hydrated when pregnant as your body needs water to form amniotic fluid, produce extra blood volume, build new tissue, carry nutrients, help indigestion and flush out your wastes and toxins (as well as the baby's).



Don't avoid cardio

The NHS encourages pregnant women to do 30 minutes of exercise every day, the level of which should enable you to continue to hold a conversation and not feel lightheaded.



If you already run then you can continue to do so but make sure you let your midwife or GP know just to be on the safe side.



If you aren't a runner then you choose things like walking, cycling or swimming. If dance or aerobics is more your thing then make sure that your instructor is experienced with teaching prenatal women and can advise you of any adaptations you may need to make.



Be kind

Give yourself a break! Some days you may feel totally exhausted, others you're raring to go. No matter what, don't stress yourself out by putting too much pressure on yourself to live out some idealistic view of what a pregnant woman should be or do.



Now is the time to figure out what is going to support your physical health and mental wellbeing so unfollow those social media accounts that make you feel like crap and unsubscribe to the demanding fitness trainer that doesn't suit your needs.



Get on the mat

Pilates is a great way to keep your body moving throughout pregnancy in a safe, effective way. Not only can every movement be adjusted to suit any body in any state (pregnant or otherwise!), it is also a great way to encourage strength and tick off your cardio for the day.



If you are looking to do prenatal Pilates then why not get in touch?! There's a range of options available to you from videos to 1:1 training.

My breastfeeding journey started the night before my c-section with my mother squeezing my breast to get the first mls of colostrum into a teeny tiny syringe so that we had something to go into hospital with. Just in case we should need it. I have always been very self-conscious of my boobs, I’ve even been uncomfortable topless in front of my husband at times, but here I was, 37 weeks pregnant and preparing for a planned but urgent c-section, tit out and being milked by my mother. I don’t have strong opinions on breast/bottle/formula, yes I wanted to give it a go to get the benefits of breastfeeding for both me and my son but, I believe that everyone is different and therefore there’s no ‘right way’. I had decided that I was going to just go with the flow in terms of breast feeding. I didn’t want to have my heart set on it, only to struggle and then feel the disappointment of using an alternative means. I was lucky, after the c-section my son latched and fed for a good few hours. I felt like I could breathe a sigh of relief, he could do it, I could do it! Unfortunately, things didn’t go as smoothly as I thought they would. He had been born early as he had stopped growing, so we had a tiny baby on our hands that needed lots of milk, but this tiny baby also had jaundice and a tongue tie. The tongue tie meant that the amount of energy he was having to use just to feed was causing him to drink for less than 10 minutes before needing a sleep. We rallied and decided that if I could pump and give him top ups of expressed breast milk then at least we could know he was getting enough, which was the main concern, however it meant that feeding him was an hour and a half long affair. First I’d breast feed, then give him a bottle top up and then either give him to my husband during the day or pop him in the moses basket at night. I’d then pump to keep my supply going and our stores up, put the milk in the fridge, clean the bottle and sterilise everything ready for the next feed…then do it all over again an hour later. I was sleep deprived and stressed. If I had less than 4 bottles in the fridge I’d feel on edge, I never knew how much of a top up he would need to have- I didn’t want to waste milk and I didn’t want to leave him hungry. My sister supplied some of her frozen breast milk to take the self-imposed pressure off for a day or so and then my mum gently suggested that I buy some formula just in case but, stubborn as ever I wanted to do it all myself. After a few weeks we had our tongue tie appointment and had to figure out another new routine, thankfully with less cracked nipples and fewer pumping sessions. I began to feel slightly less like a milk machine - I got out of the house, did human things and as time went on I got more comfortable and really enjoyed breast feeding. I am now 9 weeks in and largely feel like we’ve got this. Don’t get me wrong, some days I worry that my milk has dried up, I’m not pumping enough, his latch is wrong or that he’s not getting what he needs, but I think that that’s part and parcel of being a mum – you feel like you have it all worked out one minute and then the next you feel like you’re failing at everything. This is exactly why I feel like putting pressure on ourselves, or each other to do things a certain way is just fruitless. I’m sure that no matter what the choice, there are hard bits that just feel too much, days where you spill the milk and just feel like everything is against you. No matter what way you feed your baby, it’s important to give yourself grace over guilt. Do what you need to do to keep both you and your baby happy and healthy.

After writing about my experience with morning sickness and the effects it had on my mental health I wanted to pop a post out about some of the tips and tricks I've tried out just in case they are useful for other people! Some things I tried and they didn't work so well, some things did - we are all different and this is by no way a list designed for you to live by! But if you try some things out and it works then that's great.  I'll always recommend first and foremost that you speak to your midwife or GP about any symptoms you're concerned about, especially if you're struggling with your mental health.
