Reformer Pilates and Pregnancy: A Complete Guide for Expecting and New Mothers
Can You Do Reformer Pilates During Pregnancy?
In many cases, yes.
Many women continue practising Reformer Pilates throughout pregnancy, provided they have approval from their healthcare professional and attend classes taught by instructors with prenatal training. If you’re new to reformer work altogether, our what is reformer Pilates guide is worth reading first.
The key is modification.
As pregnancy progresses, certain exercises are adapted or removed entirely while others become more beneficial. A good prenatal instructor will adjust exercises based on your trimester, comfort level, and individual circumstances.
If you are pregnant, always inform your instructor before participating in any class.
When Can You Start and Stop Reformer Pilates During Pregnancy?
If you were already attending Reformer Pilates classes before becoming pregnant, many instructors will help you continue with appropriate modifications.
If you’re completely new to Reformer Pilates, most instructors recommend waiting until after the first trimester before starting, and only with a class specifically designed for prenatal clients.
Some women continue attending modified classes right up until a few weeks before birth, while others choose to stop earlier based on comfort, energy levels, or medical advice.
Always follow guidance from your healthcare team and instructor. For a sense of how quickly changes to your body and strength typically show up once you’re back to regular sessions, see our guide to realistic Reformer Pilates timelines.
Reformer Pilates During the First Trimester
The first trimester often brings fatigue, nausea, and significant hormonal changes.
Although physical changes may not yet be obvious, your body is already working hard behind the scenes.
During this stage, many women continue most of their normal Pilates routine with only minor modifications.
Exercises Often Emphasised
- Gentle core engagement
- Breathing exercises
- Postural work
- Glute strengthening
- Controlled lower-body exercises
Exercises That May Be Modified
- High-intensity jumping movements
- Overheating-inducing workouts
- Exercises causing discomfort or dizziness
The primary goal during the first trimester is maintaining movement while listening closely to how your body responds.
Reformer Pilates During the Second Trimester
The second trimester is when a bump becomes more visible and balance starts to shift.
Exercises Often Emphasised
- Lower back strengthening
- Postural correction work
- Side-lying exercises
- Pelvic floor awareness
Exercises Commonly Reduced or Modified
- Extended periods lying flat on the back
- Deep abdominal exercises
- Excessive twisting movements
- High-impact exercises
Many instructors begin transitioning clients away from prolonged supine positions during this stage.
Reformer Pilates During the Third Trimester
By the third trimester, comfort, stability, and preparation for birth become the priority.
The growing bump affects balance, mobility, and breathing mechanics.
Classes often focus on maintaining movement quality rather than pushing intensity.
Exercises Often Emphasised
- Side-lying work
- Hip mobility
- Glute strengthening
- Gentle upper-body work
- Pelvic floor awareness
- Breathing exercises
Exercises Commonly Avoided
- Prone (front-lying) positions
- Deep twisting movements
- Extended time on the back
- Anything causing dizziness, discomfort, or reduced movement
Real Prenatal and Postnatal Studios in Our Directory
Not every reformer studio is set up for pregnancy, so it helps to know which ones actually are. Right now our directory lists 9 studios tagged for prenatal classes and 13 tagged for postnatal classes, spread across the UK rather than clustered in one city.
A few worth knowing by name. FitWell Studios in Croxley Green runs a dedicated postnatal offering called The Baby Space alongside its regular reformer timetable, led by instructor Laura. Little Venice Pilates & Physiotherapy at Ten Health & Fitness is one of the few listings in our directory that pairs physiotherapy with prenatal and postnatal-tagged classes under the same roof, useful if you want clinical oversight alongside your sessions rather than a purely fitness-led class. And House of Reformer in Reigate, founded by Katie Martin, is tagged for postnatal classes in our own listing data.
If you’re managing a pre-existing injury, pelvic girdle pain, diastasis recti, or a more complicated pregnancy or postnatal recovery, a physiotherapist-led studio can offer a level of clinical oversight a standard class won’t. We’ve covered this in detail in our guide to physio-led Reformer Pilates, including the London clinic chain that runs prenatal and postnatal-adjacent sessions alongside general rehab work.
Returning to Reformer Pilates After Pregnancy
Many women look forward to returning to Reformer Pilates once they’ve received your postnatal sign-off.
For many women this occurs at the six-week postnatal check, although recovery timelines vary significantly depending on birth experience and individual circumstances.
Before returning to classes, consider:
- Receiving medical clearance
- Checking for diastasis recti (abdominal separation)
- Assessing pelvic floor recovery
- Starting with postnatal-specific classes where available
A qualified postnatal instructor can help you rebuild strength gradually and safely. If you’re wondering how often to attend once you’re cleared, our guide on how often you should do Reformer Pilates covers realistic frequency for different goals, postnatal recovery included.
What to Ask a Studio Before Booking While Pregnant
Not every studio offers prenatal support.
Before booking a class, ask:
- Do you offer prenatal Reformer Pilates classes?
- Are your instructors trained in pre and postnatal exercise?
- Can exercises be modified during pregnancy?
- What trimester experience do you have?
- Do you offer beginner-friendly prenatal classes?
- Do you offer postnatal-specific classes once I’m cleared to return?

Frequently Asked Questions
Do I need doctor approval before doing Reformer Pilates while pregnant?
Many studios recommend obtaining approval from your midwife, GP, or healthcare professional before attending classes during pregnancy. Requirements vary by studio, so it’s worth checking directly.
Can I lie on my back during Reformer Pilates while pregnant?
Many instructors modify prolonged supine positions during the second and third trimesters. The exact approach depends on the individual and instructor guidance.
Can I do prone exercises during pregnancy?
Prone exercises are typically removed once the growing bump makes lying on the stomach uncomfortable or impractical.
Can I use the jump board while pregnant?
Some instructors modify or remove jump board exercises during pregnancy, particularly in later trimesters. Recommendations vary based on individual circumstances and instructor experience.
Is Reformer Pilates safe during pregnancy?
Many women safely participate in Reformer Pilates during pregnancy when classes are appropriately modified and approved by their healthcare professional. Always discuss exercise plans with your healthcare provider and inform your instructor that you are pregnant.
Should I choose a physio-led studio if I have a pre-existing injury or complicated pregnancy?
It’s worth considering. A physiotherapist-led studio brings clinical assessment into the process rather than a generic starting point. Our physio-led Reformer Pilates guide explains how these sessions differ from a standard class and names studios in our directory that offer them.
