Prenatal Reformer: What to Modify and What to Avoid
Teaching a pregnant client on the reformer is not about wrapping them in cotton wool, and it is not about pretending nothing has changed. It is about understanding what shifts in a pregnant body and making clear, confident choices so your client feels safe, capable and strong. Here is the framework I use.
This is general education for instructors, not medical advice. Every pregnancy is different, and your client should have clearance from their care provider. When in doubt, choose the more conservative option.
What actually changes
Three things drive most prenatal modifications:
- Balance and centre of gravity shift. As the bump grows, the body's balance point moves, which makes anything on a moving carriage, and especially anything standing on the carriage, a genuine fall risk.
- The abdominal wall is under load. Deep loaded flexion and any move that strains the midline can be too much, particularly later on.
- Time on the back is limited. Later in pregnancy, long periods lying flat can be uncomfortable and are usually limited, so supine work gets shorter and gets swapped for side-lying or upright options.
What to avoid
Some moves are a clear no, mostly for balance and midline reasons:
- Standing on the reformer. Anything where the client stands on the moving carriage or platform, splits, standing lunges and squats on the carriage, the scooter, standing saw. A shifting centre of gravity plus a sliding surface is the wrong combination. Work the pattern kneeling or on the floor instead.
- Deep loaded flexion. Full teasers, the hundred with a heavy loaded curl, roll-overs and jackknives. The overhead and deeply flexed loaded work asks too much of the abdominal wall.
- Prone work once the bump develops. Lying face down stops being an option fairly early.
What to modify
Most of the repertoire is not off the table, it just gets adjusted:
- Shorten supine time and raise the head. Keep supine blocks brief later on, and prop the head and chest so the client is not fully flat.
- Bring stability forward. Emphasise the deep core, the glutes and the pelvic floor. Side-lying leg and glute work is gold in pregnancy, comfortable and genuinely useful.
- Lighten and slow. Reduce range before you reduce spring, keep the tempo controlled, and cue out of any breath-holding.
- Keep them upright when you can. Seated arm work, kneeling patterns and supported standing work beside the reformer are safe, strong and feel great.
What is genuinely great in pregnancy
Do not let the list of avoids make you timid. Pregnant clients thrive on side-lying glute work, seated and kneeling arm springs and rowing, supported squats beside the reformer, gentle spinal mobility, and anything that builds the deep core and pelvic floor without straining the midline. Strong, capable and supported is the goal.
Make the choices automatic
The hardest part of prenatal teaching is holding all of this in your head while you also run the class. This is why every exercise in Étude carries a prenatal flag, safe, modify or avoid, with a plain-language note and a ready alternative. When you generate a class for a prenatal client, the moves flagged avoid are simply kept out, so you are never scrambling mid-class to swap something you should not have programmed. You stay the expert. The tool just watches your back.
