WHY THE MIDWIFE CONVERSATION COMES FIRST
Every pregnancy is different, and the factors that decide whether exercise is appropriate — how the pregnancy is progressing, any complications, your history — are exactly the things a fitness instructor cannot know and should not guess at. Your midwife or GP can say yes, no, or yes-with-conditions to exercise generally and to strength work specifically. UK guidance broadly supports staying active through a healthy pregnancy, but the person who knows yours gets the first and final word.
Have the conversation early, and be specific: small-group reformer pilates, spring resistance, some work lying down. Specifics get you useful answers rather than generic reassurance.
TELL THE STUDIO — BEFORE YOUR FIRST CLASS, AND AGAIN IF ANYTHING CHANGES
Any studio worth your money asks about pregnancy before you take a class. At ours it is part of the health declaration every client signs once, and the trainer reads it before your first class — that is how they know to offer you the adapted version of an exercise without a public conversation about it mid-class.
This is not a one-off admin task. If anything changes — a new symptom, new advice from your midwife, simply feeling different — tell the studio before your next class. Adaptations take a trainer seconds to make, and they can only make them for what they know about.
HOW CLASSES ARE ADAPTED
The reformer is, in some ways, well suited to adaptation: springs can lighten an exercise or support part of your body weight, positions can be raised or changed, and ranges can be shortened. Common adjustments include replacing time lying flat on your back (generally avoided after the first trimester) with inclined, seated or side-lying versions, easing off deep abdominal work in favour of breath and stability work, and skipping anything that strains through the midline.
A small class matters more than usual here. In a room of eight with one trainer, your setup gets checked and your adaptations arrive quietly at your bed; in a room of thirty you are on your own with a moving carriage. If you are choosing a studio while pregnant, class size is a safety feature, not a luxury.
Expect the work to feel different from what you knew before pregnancy, and let it. The goal through these months is to move well and stay strong comfortably — not to progress spring weights.
FIRST TIME ON A REFORMER WHILE PREGNANT?
Starting something new mid-pregnancy deserves extra caution, and this is worth raising explicitly with your midwife: beginning reformer pilates is a different question from continuing a practice your body already knows. If they support it, tell the studio you are both new and pregnant, come early to your first class, and choose a beginner-level class where the pace assumes nothing.
Some studios also offer private one-to-one sessions, which suit pregnancy well: everything is built around you, and there is no class pace to keep. Ours are enquiry-only until opening, but the option exists.
AFTER THE BABY
Returning post-natally has its own timeline, and it is another midwife-or-GP-first conversation — commonly around the six-to-eight-week check for straightforward births, later after a caesarean, and always on their advice rather than a calendar. When you do come back, say so on your health declaration: post-natal bodies have their own adaptations, particularly around the abdominal wall and pelvic floor, and a trainer who knows can build you back sensibly.
QUICK ANSWERS
That is a question for your midwife or GP, because it depends on your pregnancy. If they are happy for you to take part, classes can usually be adapted — tell the studio you are pregnant so the trainer can adjust exercises for you.
Raise it specifically with your midwife or GP — starting something new mid-pregnancy is a different question from continuing an existing practice. If they support it, tell the studio you are new and pregnant, and pick a beginner-level class.
Many women continue exercising through the first trimester, but the deciding voice is your midwife or GP. Whatever they advise, tell your studio as soon as you know — adaptations work best from day one.
On your midwife's or GP's advice, not a calendar — commonly some weeks after your post-natal check, later after a caesarean. Tell the studio you are post-natal so classes can be adapted while you rebuild.
