Exercise After Birth: When to Start Safely

Your health matters just as much as your baby's. If you are dealing with exercise after birth: when to start safely, here is what you need to know.
The short answer
Most people can begin gentle movement like walking and pelvic floor exercises within days of an uncomplicated vaginal delivery. After a cesarean delivery, recovery typically takes longer and you should wait for provider clearance before anything beyond gentle walking. ACOG recommends that postpartum individuals can gradually resume exercise when they feel ready, rather than waiting for a specific milestone, though a postpartum checkup is important to assess readiness for higher-intensity activity.

By Age
What to expect by age
0-2 weeks postpartum
In the earliest days after delivery, focus on rest, recovery, and gentle movement. Short walks around the house and pelvic floor contractions (Kegels) are appropriate for most people after vaginal delivery. After a cesarean section, limit activity to gentle walking and avoid lifting anything heavier than your baby. Listen to your body: if an activity causes pain, bleeding, or heavy fatigue, scale back. This is not the time for structured exercise.
2-6 weeks postpartum
Gradually increase walking distance and duration as your energy allows. You can begin gentle core rehabilitation exercises, focusing on deep core activation and breathing rather than traditional crunches or planks. Avoid high-impact activities, heavy lifting, and exercises that increase abdominal pressure until cleared by your provider. If you had a cesarean, your incision needs time to heal internally. Your six-week postpartum visit is an opportunity to discuss your exercise goals and get personalized guidance.
6-12 weeks postpartum
After your postpartum checkup (usually around six weeks), most providers clear patients for a gradual return to exercise. Start at a lower intensity than your pre-pregnancy fitness level and build up slowly. Swimming can resume once postpartum bleeding has stopped and any wounds have healed. If you had diastasis recti (abdominal separation), work with a pelvic floor physical therapist before returning to traditional ab exercises. Pay attention to signs of pelvic floor dysfunction such as leaking urine during exercise.
3-6 months postpartum
By this time, most people can gradually return to their pre-pregnancy exercise routines, including moderate-intensity cardio and strength training. However, the postpartum body has undergone significant changes, and it is important to progress gradually. Ligaments remain more lax due to relaxin for several months postpartum, increasing injury risk. If you are breastfeeding, moderate exercise does not affect milk supply or composition. Stay well hydrated and feed or pump before exercising for comfort.
What Should You Do?
When to take action
- You feel ready for gentle walking within days of an uncomplicated vaginal delivery
- You experience some muscle weakness and lower endurance compared to your pre-pregnancy fitness
- Mild discomfort with certain movements that improves as you gradually increase activity
- You experience increased vaginal bleeding when you start exercising
- You leak urine during exercise, even after several weeks of pelvic floor exercises
- You notice a bulge or doming along your midline abdomen during core work, suggesting diastasis recti
- You feel pressure or heaviness in your pelvis during or after exercise
- You experience sudden heavy bleeding (soaking more than one pad per hour) during or after exercise
- You develop severe abdominal pain, especially after cesarean delivery, which could indicate wound complications
- You feel chest pain, severe shortness of breath, or dizziness during exercise

Returning to Running After Baby
Current guidelines recommend waiting at least twelve weeks postpartum before returning to running, and only after being cleared by your provider and ideally assessed by a pelvic floor physical therapist. Running is a high-impact activity that places significant demands on the pelvic floor, core, and joints, all of which need time to recover after pregnancy and birth. Returning too early can lead to pelvic floor dysfunction, urinary incontinence, and injury.
Weight Loss While Breastfeeding: What Is Safe
Gradual weight loss of one to two pounds per week is generally safe while breastfeeding and should not affect your milk supply. Most breastfeeding parents naturally lose weight over time as nursing burns approximately 450-500 extra calories daily. However, some people find their bodies hold onto weight while breastfeeding, particularly around the hips and thighs, due to hormonal changes. Crash diets, very low-calorie diets (under 1800 calories), and rapid weight loss can reduce milk supply and deplete your nutritional stores.
Pelvic Floor Weakness After Birth
Pelvic floor weakness after birth is extremely common, affecting the majority of women who deliver vaginally and many who deliver by cesarean. The muscles, ligaments, and nerves of the pelvic floor are stretched and sometimes injured during pregnancy and delivery. With targeted pelvic floor exercises and time, most women see significant improvement within the first year postpartum.

Dealing with Abnormal Prenatal Screening Results
An abnormal prenatal screening result can be terrifying, but it is important to understand that screening tests are designed to cast a wide net and have significant false-positive rates. Most people with abnormal screening results go on to have healthy babies after further testing confirms the baby is fine. An abnormal screening is a reason for more information, not a diagnosis.
Pregnancy Over 35 (Advanced Maternal Age)
While pregnancy after 35 carries some increased risks (including chromosomal abnormalities, gestational diabetes, and hypertension), the vast majority of people over 35 have healthy pregnancies and healthy babies. The term "geriatric pregnancy" is outdated and does not reflect reality. With appropriate prenatal care and monitoring, outcomes are excellent.
Amniocentesis Questions and Fears
Amniocentesis is a diagnostic test performed between 15-20 weeks that analyzes amniotic fluid to detect chromosomal conditions and genetic disorders with over 99% accuracy. The risk of pregnancy loss from the procedure is approximately 1 in 500-1,000 when performed by an experienced provider. Understanding the actual risks can help you make an informed decision.
