A Pregnant Student Just Walked Into Your Yoga Class. Now What?
You know the moment.
You're setting up for your 6pm vinyasa class, and a student walks in, catches your eye, and says, "Just so you know — I'm 16 weeks pregnant."
And you smile and say "congratulations!" while your brain does this: Okay. No twists? Or was it no closed twists? Can she lie on her back? Is savasana okay? What do I do in core work? Oh god, we're doing core work today.
If that's ever been you, I want you to know two things. One: you're not a bad teacher. Your 200-hour training probably gave you a single afternoon on pregnancy, if that. Two: this is completely fixable, and it's less complicated than the panic makes it feel.
I've been teaching prenatal yoga since 2017 and I've trained over 850 teachers in 40+ countries, and this exact scenario — the pregnant student showing up unannounced — is the number one reason teachers come to me. So let's walk through what to actually do.
First: what to say in that moment at the door
Keep it simple and warm. You don't need to interrogate her. Three things are worth asking:
"How far along are you?" Trimester matters more than anything else for modifications.
"How are you feeling in your practice lately?" She'll usually tell you exactly what you need to know — what feels good, what's been off.
"Has your provider given you any guidance about movement?" This quietly screens for complications without making it weird.
Then say the most important sentence: "I'll offer you options throughout class — you're the expert on your body, so take what works and skip what doesn't."
That's it. You've just given her permission to modify and taken the pressure off both of you.
The student who hasn't told you (and won't)
Here's the part most teachers never consider: the student in your class who is 8 weeks pregnant, nauseous, exhausted, and telling absolutely no one.
The first trimester is when most people keep their pregnancy private — and it's also when they're navigating the biggest internal changes. You will teach pregnant students without knowing it. You probably already have.
This is why "I'll deal with it when someone tells me they're pregnant" isn't really a plan. Teaching in a way that offers options, avoids forcing anyone into deep closed twists or breath retention, and never pushes students past their edge isn't just prenatal-safe teaching. It's just good teaching.
The outdated rules you can let go of
A lot of what gets passed around about pregnancy and yoga is fear-based, secondhand, and decades old. Let's clean some of it up.
"No twists, ever." Not true. Closed twists that compress the belly (think revolved chair, crossing the midline) are the ones to skip. Open twists — rotating away from the belly, twisting from the upper back (allowing space for the belly) — are generally fine and usually feel great.
"Never let her lie on her back." More nuanced than the blanket rule. Brief supine positions are generally fine, especially earlier in pregnancy. As the belly grows (typically past 20-ish weeks), some people feel dizzy or nauseous on their backs — so offer an incline with a bolster, or side-lying. The rule isn't "never on the back." The rule is "give her an alternative and let her choose."
"No core work." Skip the crunches and anything that bulges or strains the front line of the abdominals — yes. But pregnant students need their core: deep, breath-led, functional core work supports the pelvis, the back, and growing belly. Avoiding the core entirely does her a disservice.
"Pregnant students are fragile." They're not. They're often stronger and more body-aware than anyone else in the room. What they are is more mobile — the hormone relaxin loosens ligaments, which means pregnancy is not the time to chase end ranges and deep stretches. Strength and stability over flexibility. Every time.
What actually matters
If you remember nothing else, remember these:
No deep closed twists or belly-down poses once the belly is a factor.
No breath retention or intense heating pranayama. Steady, easeful breath only.
Watch the heat. Skip pregnant students out of anything designed to overheat.
Strength over stretch. Relaxin is doing plenty of stretching already.
Offer options, never singling her out. "If you're taking the supported version today..." keeps modifications available to everyone.
The honest part
Here's what I won't pretend: a blog post can get you through Tuesday's class. It cannot make you the teacher a pregnant student seeks out, trusts, and follows through her entire pregnancy — and comes back to postpartum.
That takes actually understanding the pregnant body: the anatomy, the trimesters, birth prep, the pelvic floor, what's happening postpartum. It's the difference between "modifying around" a pregnant student and genuinely teaching her.
If tonight's class is the immediate problem, start with my Prenatal Yoga Teacher's Toolkit— it's $9 and it gives you the sequences, cues, and modifications to feel steady this week.
And if reading this made you realize how much you were never taught? That's exactly what my 85-Hour Prenatal & Postnatal Yoga Teacher Training is for. It's the full Yoga Alliance RPYT path — everything from trimester-by-trimester teaching to labor prep to postnatal recovery — and it's the only thing my school does.
Because the next pregnant student who walks into your class shouldn't trigger panic. She should feel like she just found her teacher. 🫶🏼
