Pregnancy is a time of immense change, both physically and emotionally. As your body transforms to support the growing life inside you, it’s essential to maintain a healthy lifestyle, and regular exercise plays a crucial role in this. Not only can exercise during pregnancy boost your mood and energy levels, but it also helps to reduce common discomforts like back pain, improve sleep, and prepare your body for childbirth. However, it’s important to adjust your fitness routine to accommodate the different stages of pregnancy and ensure that you’re engaging in safe exercises.
In this blog, we will explore safe exercises for each trimester, providing guidance on how to stay active while protecting both you and your baby. Let’s dive into trimester-specific recommendations!
Why Exercise During Pregnancy is Important
Regular exercise during pregnancy offers numerous benefits for both mother and baby. Some of these include:
- Improved mood and energy levels: Pregnancy hormones can cause mood swings and fatigue. Exercise helps to release endorphins, which boost your mood and energy.
- Reduced pregnancy discomfort: Exercise can alleviate common pregnancy symptoms such as back pain, constipation, bloating, and swelling.
- Better sleep: Staying active can improve sleep quality and reduce pregnancy-related insomnia.
- Easier labor and recovery: Maintaining physical fitness during pregnancy helps prepare your body for childbirth and aids in a quicker postpartum recovery.
- Reduced risk of gestational diabetes and preeclampsia: Regular exercise helps manage weight gain, blood pressure, and blood sugar levels, lowering the risk of pregnancy complications.
However, as your body changes throughout pregnancy, so should your exercise routine. Let’s break down which exercises are safe and beneficial for each trimester.
First Trimester (Weeks 1-12)
During the first trimester, your body is adjusting to pregnancy, and you may experience symptoms such as fatigue, nausea, and morning sickness. However, if you feel well enough to exercise, this is a great time to establish a healthy fitness routine. Since your baby is still quite small, you can generally continue with most pre-pregnancy exercises, as long as they are safe and not too intense.
Safe Exercises for the First Trimester
- Walking
- One of the easiest and safest exercises for pregnant women, walking helps improve cardiovascular health without putting undue strain on your joints or muscles.
- Aim for at least 30 minutes of brisk walking, five days a week.
- Swimming
- Swimming and water aerobics are excellent low-impact exercises that work your entire body while being gentle on your joints. The buoyancy of water reduces pressure on your body, making it an ideal exercise during all stages of pregnancy.
- You can start with light swimming or a water-based aerobics class.
- Prenatal Yoga
- Yoga helps improve flexibility, balance, and strength while also providing relaxation and stress relief. It’s important to attend prenatal yoga classes specifically designed for pregnancy, as they focus on poses that are safe for your changing body.
- Avoid any poses that involve lying flat on your back or deep twists, especially as you progress through pregnancy.
- Stationary Cycling
- If you’re used to cycling, stationary cycling is a safer alternative during pregnancy, as it eliminates the risk of falling. It’s a great way to maintain cardiovascular health without placing too much strain on your joints.
- Strength Training
- Light strength training using dumbbells or resistance bands helps maintain muscle tone, which is especially important as your body supports more weight. Focus on maintaining proper form and avoid lifting heavy weights to prevent injury.
Things to Avoid in the First Trimester
- High-impact sports or activities with a risk of falling (e.g., skiing, horseback riding).
- Intense core exercises like crunches, which can strain the abdominal muscles.
- Overheating—ensure that you stay hydrated and avoid exercising in hot or humid conditions.


Second Trimester (Weeks 13-26)
The second trimester is often considered the most comfortable phase of pregnancy. Morning sickness usually subsides, and you may feel more energetic. As your baby bump begins to grow, it’s important to adjust your workout routine to accommodate your changing body and center of gravity.
Safe Exercises for the Second Trimester
- Modified Strength Training
- Continue strength training with modifications. Focus on exercises that strengthen your legs, arms, and back, which will help support your growing belly and prepare your body for carrying extra weight.
- Use lighter weights and opt for exercises like squats, lunges, and arm curls. Avoid lying flat on your back, as this can restrict blood flow to the baby.
- Swimming and Water Aerobics
- Swimming remains a fantastic exercise during the second trimester, as it helps alleviate pregnancy-related discomforts like back pain and swelling.
- Engage in water aerobics or gentle laps to keep your body moving without putting strain on your joints.
- Prenatal Yoga and Pilates
- Yoga and Pilates continue to be excellent options for improving flexibility, balance, and relaxation. Focus on poses that help relieve tension in the back and hips, such as cat-cow stretches and seated forward bends.
- Avoid any poses that require you to lie on your stomach or back for extended periods.
- Elliptical or Stationary Bike
- Using an elliptical or stationary bike is a safe and effective way to get your heart rate up while keeping your balance. Both of these exercises reduce the impact on your joints and are gentle on your growing belly.
- Walking
- Continue with regular walks, adjusting your pace and intensity as needed. As your belly grows, you may need to take shorter walks or switch to a slower pace, but walking remains an excellent way to stay active.
Things to Avoid in the Second Trimester
- Exercises that involve lying flat on your back for long periods, as this can compress a major blood vessel and reduce blood flow to the baby.
- Contact sports or any activity where there’s a risk of falling or injury to the abdomen.
- High-intensity interval training (HIIT) or exercises that involve sudden bursts of movement.
Third Trimester (Weeks 27-40)
By the third trimester, your baby bump is quite prominent, and your body is preparing for labor and delivery. At this stage, it’s important to focus on gentle, low-impact exercises that help maintain strength, flexibility, and mobility without overexerting yourself. As your center of gravity shifts, your balance may be affected, so exercises that promote stability are ideal.
Safe Exercises for the Third Trimester
- Walking
- Walking remains a safe and beneficial exercise throughout pregnancy. You may need to slow down or shorten your walks as your body becomes heavier, but walking helps keep your blood flowing, reduces swelling, and improves mood.
- Aim for 20-30 minutes of light to moderate walking several times a week.
- Swimming
- Swimming is one of the best exercises for the third trimester, as it alleviates pressure on your joints and allows you to feel weightless in the water. Gentle swimming or water-based aerobics can help relieve back pain and improve circulation.
- Prenatal Yoga
- Prenatal yoga continues to be beneficial, especially for relaxation and preparing for childbirth. Focus on breathing exercises, gentle stretches, and poses that relieve tension in the hips, back, and shoulders.
- Avoid deep stretches and any poses that feel uncomfortable.
- Pelvic Floor Exercises (Kegels)
- Strengthening your pelvic floor muscles is crucial for supporting the baby’s weight and preparing for labor. Kegel exercises help prevent urinary incontinence and aid in recovery after childbirth.
- You can do Kegels anywhere, by contracting and relaxing the muscles that control urine flow.
- Bodyweight Exercises
- Gentle bodyweight exercises like wall sits, modified squats, and seated leg lifts help maintain strength in the legs and core. These exercises support your posture and reduce lower back pain as your belly grows.
Things to Avoid in the Third Trimester
- High-impact activities or exercises that require balance, as your risk of falling is higher due to your shifting center of gravity.
- Lying on your back for extended periods, as this can interfere with blood circulation to the baby.
- Intense cardio or strength training that may overexert your body.
General Guidelines for Safe Exercise During Pregnancy
While exercising during pregnancy offers many benefits, it’s essential to listen to your body and make modifications when necessary. Here are a few general tips for exercising safely during pregnancy:
- Stay hydrated: Drink plenty of water before, during, and after exercise to stay hydrated.
- Avoid overheating: Wear light, breathable clothing and avoid exercising in hot or humid conditions.
- Listen to your body: If you feel dizzy, short of breath, or experience any pain, stop exercising and consult your healthcare provider.
- Focus on proper form: Maintaining proper form and posture is key to preventing injury and maximizing the benefits of exercise.
- Consult your healthcare provider: Always check with your doctor before starting or continuing any exercise routine during pregnancy, especially if you have any pre-existing medical conditions or pregnancy complications.
