First trimester exercise: what's safe, what to skip, and how to keep moving

The first trimester during pregnancy can make exercise feel more complicated than it used to. Between nausea, fatigue, and wondering what’s safe, it’s understandable if your usual routine suddenly doesn’t feel quite right.

“All pregnancies are unique in their own way,” says Dulce Bhatt, PT, DPT, a physical therapist at Hinge Health. “But for most pregnancies, staying active is one of the best things you can do for yourself and your growing baby.” The goal isn’t to push through exhaustion or hit personal records. It’s to find movement that helps your body adapt to the many changes happening during early pregnancy. Some days you may feel ready for a full workout. Other days, a short walk or a few gentle stretches may be enough — and that’s okay. It all counts.

Ahead, learn why movement matters during the first trimester, plus gentle, targeted exercises recommended by Hinge Health physical therapists to help you move more comfortably during early pregnancy.

Benefits of exercise in the first trimester

When you’re exhausted or feeling nauseated, exercise may be the last thing on your mind. But even gentle movement can help you feel better while preparing your body for the months ahead.

• May ease nausea and fatigue. It may sound counterintuitive, but activities like walking can actually help reduce two of the most common first-trimester symptoms. “Movement helps distract the brain from nausea and fatigue while calming the nervous system,” says Dulce Bhatt, PT, DPT, a physical therapist at Hinge Health.

• Supports your mood. Hormonal changes during the first trimester can contribute to anxiety, irritability, or low mood. Regular movement releases endorphins and helps regulate your nervous system, supporting both your physical and emotional well-being.

• Pelvic floor and core preparation. The first trimester is the ideal time to begin building pelvic floor awareness and function — before the load demands of later pregnancy ramp up. 

• Preps your core and pelvic floor for later stages. Early pregnancy is a great time to build awareness of your deep core and pelvic floor muscles before your growing baby places more demand on them. “It’s never too soon to prepare your body for pregnancy, delivery, and postpartum recovery,” says Dr. Bhatt.

• May help improve your sleep. Sleep changes often begin earlier than people expect during pregnancy. Regular movement can help you sleep more soundly and feel more energized during the day.

• Supports your health throughout pregnancy. Staying active is associated with a lower risk of gestational diabetes, excessive pregnancy weight gain, and preeclampsia. While exercise can't eliminate every risk, it helps support both you and your baby throughout pregnancy.

How movement can help in the first trimester

Think of the first trimester as an opportunity to build a foundation, not to train harder.

“The first trimester is really about preparing your body for what’s ahead," says Dr. Bhatt. “You're developing the pelvic floor coordination, core stability, and endurance that will support you throughout pregnancy, labor, and postpartum recovery.”

Movement also helps you become more aware of your pelvic floor before your changing anatomy makes those muscles harder to feel. Learning how to both contract and fully relax these muscles early in pregnancy makes it easier to strengthen and coordinate them later, when you’ll need them most.

Most importantly, movement is adaptable. On days when you’re feeling your best, you may be able to do your usual workout with a few modifications. On days when fatigue or nausea are in charge, a short walk, gentle stretching, or simply changing positions throughout the day can still help your body feel better.

The above exercises strengthen the muscles that support your hips, pelvis, core, and pelvic floor, which are the areas that work hardest throughout pregnancy. Building this foundation early can help your body better adapt to the changes ahead while supporting more comfortable movement throughout pregnancy, postpartum, and beyond.

Exercises to avoid during the first trimester

For most healthy pregnancies, moderate exercise, which can include walking, swimming, strength training, and prenatal yoga, is generally safe. Instead of avoiding movement altogether, think about making small adjustments so you can continue moving comfortably as your body changes. In general, it's a good idea to avoid the following activities:

• Contact sports and high fall-risk activities. Some intense exercises can be okay during pregnancy, but it’s important not to push past what feels manageable for your body. Sports such as skiing, horseback riding, and martial arts increase the risk of falls or direct blows to the abdomen, which are never safe during pregnancy.

• Hot yoga and exercise in extreme heat. Skip hot yoga and be mindful of overheating. A good rule of thumb is the talk test: you should be able to carry on a conversation while exercising. Take breaks, stay hydrated, and cool down when needed.

• Scuba diving. Scuba diving isn’t considered safe during pregnancy because of the risk of fetal decompression sickness, which can interrupt blood flow to the baby and potentially lead to serious complications.

• Pushing through concerning symptoms. Exercise shouldn’t make you feel worse. Stop and contact your healthcare provider if you experience vaginal bleeding, significant abdominal pain or cramping, chest pain, dizziness, or severe shortness of breath.

When to see a doctor

First-trimester exercise is recommended for most healthy pregnancies, but it’s always a good idea to check in with your healthcare provider if you’re unsure about what’s right for you. Stop exercising and contact your provider if you experience:

• Vaginal bleeding or spotting

• Dizziness, fainting, or a persistent headache during exercise

• Chest pain or shortness of breath that feels out of proportion to your activity

• Painful contractions or persistent abdominal cramping

It’s also worth talking with your provider before starting a new exercise routine if you’ve had pregnancy complications in the past, have been advised to limit activity, or have another medical condition that could affect your pregnancy.

Tips for a successful first trimester workout routine 

The first trimester can be unpredictable. Some days you’ll have the energy for a full workout, while other days a short walk may be all that feels manageable. Both are okay. The key is finding ways to keep moving that work with your body, not against it. Consider these tips:

• Start where you are. If you exercised before pregnancy, you can often continue with a few modifications as needed. “If you're new to exercise, begin with gentle movement and build gradually,” says Dr. Bhatt. “Pregnancy isn't the time to dramatically increase your training.”

• Use the talk test. Moderate exercise should leave you breathing a little harder, but you should still be able to carry on a conversation. If you can’t, ease up on the intensity.

• Aim for consistency, not intensity. Experts recommend about 150 minutes of moderate activity each week, but you don’t have to do it all at once. “Even a 10-minute walk counts,” says Dr. Bhatt. “Those shorter sessions really do add up.”

• Break movement into smaller chunks. If your fatigue or nausea make longer workouts feel overwhelming, try taking small movement snack breaks throughout the day. Even getting up to stretch or changing positions regularly can help reduce muscle stiffness.

• Build pelvic floor awareness early. Pregnancy places increasing demands on your pelvic floor over time. Learning how to both contract and fully relax these muscles now can help support your body throughout pregnancy, labor, and postpartum recovery. “Even a few minutes of targeted pelvic floor exercises daily in the first trimester builds a foundation that matters for delivery and postpartum recovery,” explains Dr. Bhatt. 

• Listen to your body and adjust. Some days you'll feel stronger than others. On days when your symptoms are more intense, gentle walking, stretching, or simply spending a few minutes outside may be exactly what your body needs. Modifying your workout doesn't mean you're falling behind; it means you’re adapting to pregnancy.

PT tip: Movement is self-care 

When you’re tired or nauseated, exercise may be the last thing you want to do. That’s completely understandable. But even small amounts of movement can help you feel better, both now and throughout the rest of your pregnancy.

“I like to tell people to think of movement like taking their prenatal vitamins,” says Dr. Bhatt. “You don’t have to get it exactly right. A little movement each day can help support you and your baby throughout pregnancy, delivery, and recovery.”
