Does Working Out Affect Pregnancy?

If you’re wondering whether it’s safe to work out while pregnant, the answer is generally yes – as long as you’re careful and listen to your body. However, there are a few things to keep in mind.


Pregnancy is a time of joy and excitement, but it can also be filled with difficult medical decisions. One such dilemma is the question of how to balance a healthy level of physical activity during pregnancy with the risk of potential harm to your unborn child. Though opinions vary on the answer, research has shown that light to moderate exercise can actually be beneficial for both mother and baby. In this guide, we’ll examine how different types of physical activity affect pregnancy and explore which exercises are safe and effective for expecting mothers.

Benefits of Exercise During Pregnancy

Exercise during pregnancy can be beneficial for both the mother and the baby. It can help to reduce the risk of certain complications, increase energy levels, and improve mood. Exercise can also help the mother maintain a healthy weight gain during pregnancy, aiding in an easier birth and recovery. Let’s take a look at some of the benefits of working out while pregnant.

Improved Mood

Exercise during pregnancy is well known to improve mood and reduce stress. It triggers the release of endorphins, which are hormones that create feelings of euphoria and pleasure. This endorphin rush can leave you with a feeling of satisfaction and relaxation for hours after exercising. Physical activity also increases the secretion of serotonin, another hormone that can help reduce stress levels as well as alleviate fatigue, headaches, and insomnia. In addition to improved mental health benefits from regular exercise during pregnancy, such as improved sleep patterns and fewer long-term symptoms of depression, it has been found to have positive effects on fetal development. Research has revealed that pregnant women who exercise regularly have better overall psychological health — a reduction in anxiety symptoms, an increase in self-confidence and self-esteem, as well as healthier relationships with their partners.

Reduced Stress and Anxiety

Exercising during pregnancy has been associated with various benefits, including reduced stress and anxiety. According to research, moderate-intensity aerobic exercise may have stress-reducing effects by helping to reduce cortisol levels and improve cardiovascular health. Additionally, exercise has been shown to improve mood and reduce negative thinking, both of which can be helpful to the mother’s mental health.

Regular exercise during pregnancy can also help keep the mind sharp and lead to improved focus. When a woman engages in regular physical activity during pregnancy, it is associated with increased cognitive stimulation that can help her stay alert and keep her mind active. Further, exercising during pregnancy may aid in reducing fatigue by providing a good source of energy for both mother and baby.

Moreover, exercising during pregnancy has also been linked to improved quality of sleep amongst pregnant women who are able to fall asleep faster and stay asleep longer when compared to those who do not take part in regular physical activity throughout their pregnancy. Lastly, exercise is crucial for keeping blood sugar levels in check while pregnant which helps prevent gestational diabetes from developing.

Improved Sleep Quality

It is no secret that pregnant women often experience interrupted sleep due to extreme fatigue, frequent bathroom trips, and physical discomfort. However, exercising during pregnancy can provide some relief and improve overall sleep quality. Regular exercise can lead to improved sleep quality for the duration of pregnancy, as well as after childbirth. Exercising improves circulation and can relieve muscle tension from tired or aching muscles. Additionally, it stimulates endorphin production which can reduce stress levels and improve overall mood. Reduced stress hormones naturally lead to deeper, more restful sleep. There are a variety of prenatal exercises that have been proven to help with improving sleep quality throughout the entire pregnancy, including walking or light jogging, swimming and yoga or stretching exercises designed specifically for pregnant women.

Reduced Risk of Gestational Diabetes

Exercise can help expectant mothers to maintain a healthy weight and body composition while avoiding unnecessary weight gain during pregnancy. According to the American College of Obstetricians and Gynecologists (ACOG), gaining too much weight during pregnancy is a risk factor for the development of gestational diabetes. Regular physical activity, when combined with nutritious eating, can help expectant mothers stay within the recommended guidelines for safe and healthful pregnancy weight gain.

Additionally, research suggests that pregnant women who are active during their pregnancies have a lower risk of developing gestational diabetes than pregnant women who are inactive or have low levels of exercise. Furthermore, regular physical activity can also help decrease a woman’s risk for other health conditions such as high blood pressure and preeclampsia, which are complications that can arise in pregnancy due to changes in hormone levels or excessive weight gain.

Types of Exercise During Pregnancy

Exercising during pregnancy can be beneficial to both the mother and the baby. It can help improve muscle tone and strength, reduce stress and fatigue, and can even help with the process of labor and delivery. However, if done incorrectly, exercising during pregnancy can be dangerous. Therefore, it is important to be aware of the types of exercise that are safe to do during pregnancy. Let’s take a closer look.


Walking is a safe, low-impact exercise that can be done throughout your pregnancy. Aim for 30 to 60 minutes of walking each day, but anything is better than nothing. Walking is a simple way to get your body moving and prepare for labor. Be sure to listen to your body about how much you can do. If you are feeling tired, slow down or take a break.

Make sure you find comfortable shoes with good support and consider adding an abdominal support belt which can provide extra support for your lower back and abdomen. Walk in areas with good footing, especially in the later stages of pregnancy when balance can be an issue due to added weight and shifting posture as the baby grows. When possible, walk with friends or family members who can provide gentle reminders if your form falls by walking too quickly or if you don’t take breaks often enough.


For pregnant women, swimming can be a great low-impact way to get exercise because it is easy on your joints while providing an effective cardiovascular workout. Additionally, the sensation of being weightless in the water helps relieve joint and back pain associated with pregnancy.

Swimming doesn’t require any special skills or equipment and gives you the freedom to move around in different ways. It also reduces swelling in your lower limbs and can help prevent varicose veins from developing during pregnancy. You can choose to swim laps if you’re comfortable doing so or perform various exercises within the pool such as water aerobics that focus on strengthening your back and abdominal muscles, as well as toning your arms and legs.

Safety should always be kept in mind when exercising while pregnant — consult your doctor before you begin any exercise program, make sure you stay hydrated, wear a supportive swimsuit, use extra caution if there is a risk of falling or slipping, and do not overexert yourself. Swimming can provide numerous physical health benefits for both mom and baby throughout every trimester of pregnancy.


Yoga is an excellent exercise program to consider during pregnancy. It helps to provide a low-impact and full body workout that is safe for both you and your baby. Yoga focuses on mindful movements, mindfulness and breathwork, which can serve to help alleviate pregnancy-related stress and low back pain. Additionally, there are relaxation techniques incorporated into the practice that can be helpful in reducing both physical and emotional distress throughout the last trimester of your pregnancy.

Yoga classes that are specifically designed specifically for pregnant women can be taken with a qualified instructor who can focus on proper form, safety precautions, and provide modifications as needed based on individual needs throughout pregnancy. Yoga classes vary in intensity levels catering to beginner through advanced practitioners; however some poses may need to be modified as your body changes during each trimester. Common yoga poses for expectant mothers might include cat/cow poses for stretching out the lower back muscles; cobra pose for strengthening the spine; bridge pose for toning the abs; warrior I/II poses for strengthening legs & thighs; hip circles & squats to loosen up hips & strengthen glutes; pigeon pose for deep hip opening stretch ++ many more!

Low-impact Aerobics

Low-impact aerobics, such as walking, swimming, and stationary cycling can help improve circulation, enhance mood and reduce fatigue during pregnancy. This type of exercise will provide you with the same cardiovascular benefits as high-impact activities but without the risk of straining your joints or muscles. Low-impact aerobics keep your heart rate elevated while strengthening your heart muscle (which is important for breastfeeding after birth).

If you have a medical background or are comfortable performing certain exercises, you may wish to consider introducing some strength training exercises into your routine. Remember to use light weights and focus on correct form to ensure muscle balance and stability. Concentrate on breathing properly during strenuous activities like weight lifting and intense cardio exercise which can be light brisk walking or swimming. Be sure to stay within the recommended guidelines for physical activity by your health care provider.

For those who are not used to exercising regularly or strength training – make sure to start gradually in order to safely build up stamina and enjoy the benefits of regular exercise during pregnancy. Simple stretching before workouts can help you stay flexible, reduce discomfort particularly in the back area and increase mobility. Avoid overly vigorous exercise immediately after eating – it can cause indigestion and low blood sugar levels which can be dangerous for both you and baby during pregnancy!

Risks of Exercise During Pregnancy

Exercise can be a beneficial way to keep fit and healthy during pregnancy, however there are also risks that come with being too active while pregnant. It is important to remember that each pregnancy is unique and will require different levels of activity depending on the individual. This section will examine the potential risks of exercise during pregnancy, so you can make an informed decision about your health and wellness.

Risk of Injury

Exercise during pregnancy has many physical and mental health benefits, but mums-to-be should be aware of the potential risk of injury due to altered body mechanics, weakened abdominal muscles and joint laxity caused by relaxin. It’s vital to maintain proper form while exercising as there is an increased risk of worsening low back pain and other musculoskeletal related issues.

Women who are inclined to perform high impact exercises before pregnancy shouldn’t hesitate to slowly introduce or reintroduce them during the second trimester, but the progression should be gradual. The American College of Obstetricians and Gynecologists recommend pregnant women talk with their healthcare provider first in order to understand modifications that are safe for each stage of pregnancy. In addition, it’s important for pregnant mothers to assess how their body is feeling during exercise as there may be signals that a particular move or intensity is too much for their body at a certain point in time.

Pre-existing injuries need extra attention during pregnancy as individuals often become less tolerant to injury due to back pain, hip pain etc., and perinatal muscle injury can result in higher rates of disability postpartum. Thus it’s important for women not just monitor their perceived exertion levels but also avoid movements that cause symptoms such as sharp/jerky joint movements, any sensations of instability or other pain sensations such as backache or sciatica that persist beyond exercise sessions.

Risk of Overheating

It is absolutely imperative that women who are pregnant take extra care to ensure they do not overheat, as an elevated body temperature for a prolonged period of time can lead to serious complications for the unborn baby. When exercising, especially during pregnancy, it is important to consider the environment in which you are performing your activity. Working out in hot and/or humid environments increases the risk of overheating and dehydration, both of which are associated with poorer outcomes for pregnancy. Additionally, high intensity exercise can further increase your core body temperature, so if the weather is hot or humid then consider lower-intensity activities and make sure to monitor yourself closely. It is safe to exercise outside in moderately warm temperatures as long as you stay cool and hydrated. Avoiding hot tubs, saunas and steam rooms during pregnancy is also advised. Make sure you listen to your body throughout each workout so you don’t overexert yourself or become too hot.

Risk of Preterm Labor

Regular exercise during a healthy pregnancy is generally considered safe and beneficial, providing numerous health benefits for both moms and babies. But, as with anything in life, there can be risks as well. For instance, vigorous or intense workouts may increase the risk of preterm labor or maternal injury. Preterm labor is defined as any labor prior to 37 weeks gestation and it can lead to a wide range of complications for both mother and baby.

Risk factors for preterm labor include physical activity (especially high-intensity exercise or activity that involves a lot of bouncing or jumping), dehydration, inadequate nutrition and abnormal cervical length. In addition to monitoring your diet and hydration levels, it’s important to listen to your body when exercising during pregnancy. Stop what you are doing if you feel discomfort, abdominal pain or contractions — even light spotting can indicate preterm labor. It’s best to speak with your doctor before beginning any intensive activities such as weightlifting or running while pregnant.


In conclusion, physical activity during pregnancy is beneficial for both mother and baby and should be encouraged. However, it is important to take certain precautions when exercising during pregnancy. Intense activities and exercises which involve heavy lifting or intense bouncing should be avoided, as these can cause potential health risks for mother and baby. Careful consideration should be given to a woman’s individual circumstances to ensure that any exercise undertaken is appropriate for her stage of pregnancy. Regular consultation with a doctor or healthcare professional is advised when beginning any exercise program during pregnancy.
