A Guide to Exercising While You're Pregnant

Finding out you are pregnant brings about many new emotions, some of which may be tied to the physical changes that are part of pregnancy. These changes can make it challenging to stay physically active, and choosing the right fitness program may feel overwhelming. 

But exercise during pregnancy has lots of benefits for you and your growing baby. This article will break down the basics to help you get started on a prenatal exercise program and stay physically active through each trimester.

Being physically active while you’re pregnant has some major perks for you and your baby. An increasing amount of research shows that regular exercise during pregnancy has more benefits than risks for most moms-to-be. The benefits of exercise during pregnancy include:

• Improved psychological well-being. Prenatal exercise helps with your mood not only during pregnancy but is also associated with lower levels of depression postpartum.
• Reduced risk of developing gestational diabetes and pre-eclampsia.
• Maintenance of a healthy weight. The goal of exercise during pregnancy isn’t to burn calories but rather to help your body continue to be efficient in using calories to prevent excess weight gain.
• Relief from common pregnancy complaints like constipation and sleep difficulties.
• Helping your body prepare both physically and mentally for labor and delivery.

Prenatal exercise may:

• Lower the risk of passing down metabolic conditions like obesity to your baby.
• Give your baby a head start in brain development.
• Increase the chance that your baby is born at a healthy birth weight.

Your prenatal fitness plan should help you strengthen the muscles weakened by pregnancy, lengthen the muscles that get tight during pregnancy, help you manage stress, keep your heart and lungs healthy, and keep your core strong. 

Here’s a breakdown of the three main components of a pregnancy exercise program:

1. Train all of the major muscle groups (chest, back, glutes, hamstrings, quads) through movement patterns (squat, hinge, lunge, push, pull) at least 2 days per week if you’re doing full-body workouts, or more frequently if you’re splitting up the muscle groups.
2. Use moderate to vigorous intensity aerobic/cardio exercise to elevate your heart rate and increase your breathing. Most people will prefer low-impact exercise. A few safe pregnancy workouts that are low-impact include brisk walks, elliptical, indoor cycling, or swimming, but that’s not to say that if you’re a runner you can’t keep running if approved by your doctor. You should accumulate at least 150 minutes per week if you’re performing moderate-intensity exercise or 75 minutes if you prefer more vigorous activities. These could include more of an interval style workout or other formats of group exercise classes.
3. Prenatal yoga, mobility training, or stretching will help you adapt to postural changes and muscle tightness. This type of movement can be performed during warm-ups and cool-downs or as a stand-alone session.

Although not included in the exercise guidelines, remember things like sleep, recovery, hydration, and how you fuel your body with food are important when it comes to making the most of your prenatal fitness program.

Generally, most exercises are safe during pregnancy. However, there are a few types of activities that you should avoid or approach with caution:

• Activities with a high fall risk, like gymnastics, horseback riding, or skating.
• Impact sports that could harm your belly, like boxing or hockey.
• Activities that include lying flat on your back for prolonged periods.
• High-pressure activities like skydiving and scuba.
• Exercising at an altitude above 6,000 ft (unless you already live there).

When it comes to your health and your baby’s safety, ask your doctor if you have any individual health complications that may require you to abstain from certain workouts.

Prenatal exercise guidelines recommend that you individualize your prenatal fitness plan. This means there isn’t a one-size-fits-all approach, and the exercises you find on a list of the “best exercises for each trimester” may not be the right ones for you. 

So, how can you personalize your prenatal fitness plan?

It’s safe to begin an exercise program during pregnancy, but if you’ve never run before, pregnancy probably isn’t the best time to start. If strength training is new to you, it’s best to learn the technique first and gradually progress to more challenging movements. Remember to work within your ability, and if you are inexperienced, choose beginner-friendly exercises. 

Pregnancy is a great time to seek professional support from a qualified prenatal fitness professional. Although there isn’t a directory of prenatal/postpartum experts, consulting the United States Registry of Exercise Professionals is a great place to find highly qualified exercise professionals in your area. 

If you come across online programs or classes at your local gym, be sure to ask for credentials. Your instructor or trainer should have prenatal/postpartum-specific training or certifications. 

Choose an activity that doesn’t feel like a chore. Not into walking? Try dancing instead. Your program is only beneficial if you stick with it, so don’t base your choices on what other people are doing. Find a way to move your body in a way that you enjoy.

It’s common to feel fatigued during the first trimester. This would be a good time to keep your intensity low and allow for recovery between workouts. If you have plenty of energy in the morning, adjust your schedule so you can be active then. If you notice you’re sore after strength training, try less volume during your next workout.

Although you may be able to attend your favorite fitness classes well into your pregnancy, if you find yourself having to modify a lot of moves throughout the class, it’s not serving you like it used to, and it’s time to find a program designed for your changing body.

You’ve probably heard of Kegels, but that might be where your knowledge on strengthening pelvic floor muscles during pregnancy ends. Pelvic floor training during pregnancy helps maintain a strong core so you feel stable enough to perform daily movements and complete workouts. These muscles also prevent leaking urine when you sneeze or cough. 

Like any other muscle, pelvic floor muscles can be strengthened and lengthened. You want your muscles to be strong enough to adapt to the weight of your growing belly, but you also want to know how to relax them for labor and delivery. If you’re not into kegels, you can contract and relax your pelvic floor muscles when performing other strength exercises, making it more functional and saving you time.

Being physically active and staying consistent with a prenatal exercise program can be amazingly beneficial to you and your baby. With all of the positive outcomes you’ll experience by exercise during pregnancy, it’s well worth taking the time to identify the plan and exercises that are right for you!
