Pregnancy & Postpartum Training FAQ
Common questions from expecting and new mothers about safe, effective training
When can I start training during pregnancy?
If you have a healthy, uncomplicated pregnancy and your provider approves exercise, you can train throughout all three trimesters. Many women continue their existing routines with smart modifications. If you’re new to exercise, we start conservatively and build from there. We always recommend getting clearance from your OB or midwife before we begin.
What exercises are safe during pregnancy?
Most exercises are safe with proper modification—including strength training, which is actually recommended during pregnancy. We focus on maintaining strength, preparing your body for delivery, and reducing common discomforts like back pain and sciatica. We modify exercises trimester-by-trimester based on how you’re feeling, your energy levels, and your changing body. Some movements we avoid; many we simply adapt.
Will exercise hurt my baby?
No—exercise during a healthy pregnancy is actually beneficial for both you and baby. Research shows it can reduce gestational diabetes risk, improve labor outcomes, and support healthy fetal development. As certified pre-natal specialists, we know exactly which exercises are safe and how to modify them as your pregnancy progresses. We always work within guidelines approved by ACOG (American College of Obstetricians and Gynecologists).
When can I start postpartum training?
Most providers clear patients for exercise at 6 weeks postpartum (8-12 weeks for C-sections). However, “cleared for exercise” doesn’t mean “cleared for everything.” We start with foundational core and pelvic floor work, then progressively add intensity. Some women come to me years after delivery still dealing with diastasis or pelvic floor issues—it’s never too late to address these properly.
What if I had my baby years ago but still have core issues?
It’s never too late. We work with women who are 5, 10, even 15+ years postpartum who never properly addressed their diastasis or pelvic floor dysfunction. The body responds to correct training at any point—you just need the right approach. Many of these women see significant improvement within 8-12 weeks of consistent, proper exercise.
How is postpartum training different from regular training?
Postpartum training requires understanding what your core and pelvic floor went through during pregnancy and delivery. We don’t just jump into crunches and planks—that can actually make diastasis worse. Instead, we rebuild from the inside out: restoring core function, addressing any separation, strengthening the pelvic floor, and only then progressing to more demanding exercises. It’s a specific protocol, not generic “get back in shape” training.
What is diastasis recti and how do I know if I have it?
Diastasis recti is the separation of the rectus abdominis (your “six-pack” muscles) that commonly occurs during pregnancy. Signs include a visible bulge or “coning” when you do a crunch motion, lower back pain, poor posture, and a weak core that doesn’t improve with regular ab exercises. We’re certified in diastasis recti assessment—we measure your separation, test your core function, and create a targeted protocol.
Can diastasis recti be fixed without surgery?
In most cases, yes. The majority of women see significant improvement with proper exercise protocols. The key is doing the RIGHT exercises—many common ab exercises (crunches, sit-ups, planks) can actually make diastasis worse. As certified specialists, we use evidence-based rehabilitation protocols that restore core function and reduce separation. Surgery is typically only needed in severe cases that don’t respond to conservative treatment.
How long does it take to heal diastasis recti?
Most women see measurable improvement within 8-12 weeks of consistent, correct exercise. However, full restoration depends on the severity of your separation, how long you’ve had it, and your consistency with the protocol. Some women heal faster; others need more time. The good news is that proper training almost always helps, regardless of how long it’s been since you gave birth.
Where do you train pregnant and postpartum clients?
We offer three options: our private studio in San Mateo (120 2nd Ave), in-home training throughout the Bay Area (San Mateo, Mountain View, Palo Alto, Menlo Park, and surrounding cities), or virtual sessions if you prefer training from home. Many pregnant clients appreciate in-home training as their due date approaches—no commute, train in your own space, and we bring all the equipment.
Do you work with my OB, midwife, or pelvic floor PT?
Absolutely. We collaborate with your healthcare providers to ensure your training aligns with any medical considerations. If you’re working with a pelvic floor physical therapist, we coordinate with them so your training supports (not conflicts with) their work. This team approach ensures the safest, most effective results.
What are your hours and how do I schedule?
Studio hours are Monday-Friday 6AM-8PM, Saturday 8AM-4PM, Sunday 8AM-3PM. We accommodate early morning sessions before work and evening sessions after. For in-home training, we have more flexibility based on our travel schedule. Book your free consultation through our calendar link—we’ll discuss your stage of pregnancy or postpartum recovery, your goals, and which training option fits best.
