What's the difference between private and group Pilates?
A private is one client, one instructor, for a full session. A duet is two clients sharing one instructor. A group class runs anywhere from a handful of people up to twenty-plus, depending on the studio. The smaller the ratio, the more individual attention and correction you get, and the more it costs per session.
The format you're in shapes what you actually get out of the hour. In a private, the whole session is built around your body, your goals, and whatever you're working around that day. In a group, you follow a set sequence the teacher leads, with corrections shared across the room. Both can be done on a reformer or on the mat. The reformer Pilates guide explains the machine itself, and the mat Pilates guide covers the floor-based format, so this page focuses on the private-versus-group decision rather than the equipment.
One thing worth setting straight early: a private isn't automatically "better." It's more attention, which is exactly what some people need and others don't. A confident, injury-free beginner in a capped class of ten with a good teacher is often learning perfectly well, and paying a lot less for it.
When is group Pilates the right choice?
Group is the right choice for most healthy beginners and most people training for general strength, tone, and fitness. It's cheaper per session, the energy of a class keeps a lot of people consistent, and a good studio caps boutique reformer classes at 8 to 12 so the teacher can still correct you in real time. If you can learn comfortably in that setting, you're getting most of the benefit at a fraction of the private cost.
Group suits you if you're starting from general good health, you respond well to following a led sequence, and you want to build a sustainable habit without a big per-session outlay. healthdirect's guidance for starting safely is to learn the basics with a qualified instructor and to tell that instructor if you're a beginner so they can give you extra support during the class. A good studio also runs a dedicated beginner series before dropping you into mixed-level groups, which closes a lot of the gap between group and private for a newcomer.
Where group falls short is attention. In a class of twenty, the teacher physically can't watch every body every minute. If you need hands-on correction, have something specific to work around, or learn slowly and want it watched closely, a pure group setting may not give you enough.
When is a private or duet worth the cost?
A private earns its higher cost when you need the teacher's full attention, and there are a few clear situations where that's true. If you're recovering from an injury or surgery, pregnant, managing a health condition, or you want to progress technique quickly and precisely, one-on-one time is where that happens. healthdirect notes that beginners or people with an injury may need a one-on-one session so an instructor can assess them properly before joining a class.
Some studios build this in as a requirement. They'll ask new clients, especially anyone with a complex injury history, to do a private assessment or a short series of privates before joining group reformer classes. That's often a legitimate safety step, not just an upsell, though it's fair to ask which it is and why.
A duet is the middle option people forget. Two clients with one instructor splits the cost while keeping the ratio small, so you get far more attention than a group for less than a full private. If you've got a friend or partner at a similar level, a duet can be the best value-per-attention deal in the building. Ask the studio whether they run them.
Private and group Pilates: the cost trade-off
Group is the cheaper tier, full stop, and the gap is large. Across Australia in 2026, casual group reformer classes typically run $35 to $60 and casual mat classes $20 to $35, with class packs of 5 or 10 usually saving roughly 15 to 25% per class and unlimited reformer memberships sitting around $200 to $350 a month. These are typical ranges that vary by studio and city. Our Pilates cost guide breaks down every group tier in detail.
Private sessions cost more per session than any group class, and the range is wide enough that a single national figure would mislead you. Privates are priced per studio and per instructor, with senior and clinically trained teachers charging more, so the only reliable number is the one the studio quotes you. Ask directly, and ask whether a duet brings the per-person cost down. Many studios also sell private packs at a lower per-session rate than casual privates, so ask about those too.
The honest way to think about the trade-off: you're buying attention, and attention is expensive. Pay for it where it changes the outcome (a safe start around an injury, faster technique progress, a condition that needs adapting) and skip it where a good group class would have taught you the same thing for a third of the price.
How to choose: a quick decision guide
Work through these in order. They'll usually point you to the right starting format.
- Are you managing an injury, recent surgery, pregnancy, or a health condition? Talk to a physiotherapist or a clinical Pilates provider first, then likely start with privates. (More on this below.)
- Are you a healthy beginner with no specific issue? A beginner group series is almost always the right and cheaper start.
- Do you learn slowly or want close, hands-on correction? Consider a few privates up front, then move to group once you've got the basics.
- Do you have a friend at a similar level and want attention without the full private price? Ask about a duet.
- On a tight budget but want some individual attention? A short private series to learn safely, then group for ongoing volume, is the most cost-effective hybrid most studios offer.
A pattern works for a lot of people: two or three privates to learn spring settings, safe transitions, and the core repertoire, then group classes for everything after that. You pay for attention exactly where it matters most (the start) and switch to the cheaper tier once you can hold your own.
A note on injury, rehab and clinical Pilates
If you're dealing with pain, a recent injury, surgery recovery, or a diagnosed condition, the first conversation isn't with a studio, it's with a qualified health professional. See your GP or a physiotherapist about whether Pilates suits your situation and what to avoid. healthdirect advises telling your instructor if you're recovering from an injury so they can adjust the exercises, and to stop and ask for guidance if you feel any pain.
"Clinical Pilates" usually means Pilates delivered or overseen by a physiotherapist or in a rehab-focused setting, and it's a different proposition from a general studio class. If your goal is rehabilitation rather than general fitness, that's the direction to look. The Pilates Association Australia keeps a directory you can use to find a registered studio or instructor, and their guidance on choosing a studio or training organisation is a sensible starting point for checking qualifications. This page is general information, not medical advice; for anything to do with an injury or condition, your physiotherapist or GP is the right call.
