Pre and Postnatal Fitness Series Part 3: How will My Pregnancy Affect My Workout?

How Changes in Your Body During Pregnancy Will Affect Exercise

During pregnancy, your body will undergo many changes that you will be constantly adjusting to. Some of these changes can and will directly affect how you exercise, and it’s important that you are aware of them. Let’s discuss some of these changes:

  1. Balance – Pregnancy changes your center of gravity to shift it more forward and upwards due to the extra weight in front of your body. This can place stress on your low back and pelvis and can increase your risk of falling. Be aware of how your changing body and size may affect your balance and it’s best to avoid any type of exercise where there is a high risk of falling such as skating, skiing, horseback riding, and some contact sports.

  2. Joints – Hormonal changes during pregnancy cause your ligaments that support your joints to become more relaxed. For this reason, you may want to avoid jerky or high-impact activities – like plyometric training – and exercise caution during stretching to reduce your risk of overstretching or injury.

  3. Breathing – Your oxygen requirements increase during pregnancy to support your growing child. This may impact your capacity for strenuous or high intensity exercise as you may feel more out of breath than usual during your workouts (especially during the second and third trimesters). Be sure to adjust the intensity of your exercise as needed.

  4. Heart rate – Total blood volume, heart rate and cardiac output, the amount of blood your heart pumps per beat, all increase during pregnancy to support blood flow to you and your growing child. At the same time, total vascular resistance decreases. This means that your heart rate may not increase as much during exercise as it did prior to pregnancy. This is just something to be aware of. It is more common to use the Talk Test, which I will get to in a later section, or a scale of perceived exertion to assess exer

These are just a few of the many changes to be aware of, as exercising during pregnancy will likely feel much different than exercising before. Your body is undergoing a lot of change, and it’s important to remember to always listen to your body, it knows best.
