What does the guidance say?
The American College of Obstetricians and Gynecologists (ACOG) advises that, in the absence of complications, most pregnant people benefit from regular physical activity, and that core- and posture-focused exercise can help with common pregnancy discomforts. Always confirm with your own OB-GYN or midwife before starting or continuing.
When can you start prenatal Pilates?
Many studios introduce dedicated prenatal Pilates from the second trimester (after about 12 weeks) once you have a doctor's clearance, though people already practicing may continue earlier with modifications. Your provider and instructor should guide the timing for your situation.
What gets modified during pregnancy?
A prenatal-trained instructor typically avoids prolonged lying flat on your back later in pregnancy, deep abdominal flexion, and movements that strain the abdominal wall, and instead emphasizes pelvic-floor awareness, breathing, posture, and safe strength. Spring resistance on the reformer is adjusted to your stage.
How we run prenatal Pilates
Our prenatal classes are small and led by instructors experienced with pregnant clients, so movements are scaled to your trimester and history. We ask for your provider's clearance and adapt every session to how you feel that day.
Common questions
- When should I stop lying on my back during pregnancy Pilates?
- Many providers suggest limiting time flat on your back after the first trimester. A prenatal-trained instructor will offer inclined or side-lying alternatives — follow your own provider's advice.
- Do I need my doctor's permission to do prenatal Pilates?
- Yes — get clearance from your OB-GYN or midwife before starting, and let your instructor know about any complications so they can modify appropriately.
