Private vs Group Pilates: Which Is Right for You?
By Katherine, Lead Instructor, Certified Pilates Instructor · Last updated: September 2026
Private Pilates gives you an instructor's full attention, real-time form correction, and a session built entirely around your body and your goals, which makes it the stronger starting point if you have an injury, are pregnant or postpartum, or want to progress quickly toward a specific goal. Group classes cost less per session and add social, shared-energy motivation. Many clients get the best of both by blending the two formats.
Key takeaways
Private sessions mean one instructor focused on you for the full hour: pace, programming, and cues are adjusted in real time.
Group classes follow a set format at a more general pace, cost less per session, and add social energy.
If you have a diagnosed condition, are pregnant or postpartum, or are working toward a specific, individual goal, starting with private or semi-private sessions lets your program be built around you.
Semi-private (duet) and small-group formats sit between the two, offering more personal attention than a full class at a lower cost than 1:1.
A blended plan — for example, one private session plus one or two group classes a week — is a common and practical way to get individualized attention without the cost of an all-private schedule.
What's the difference between private and group Pilates?
The two formats differ in four practical ways: attention, pace, programming, and cost.
In a private session, one instructor works with you alone for the full hour. They watch every repetition, adjust the exercise the moment your form drifts, and can change the plan mid-session if something isn't working for your body that day. The pace is set entirely by you — an instructor can slow down to teach a new movement carefully or move quickly through exercises you already know well.
In a group class, one instructor leads several people through a shared sequence. The pace is set for the room, so cueing is more general and correction happens when the instructor has a moment to reach you, not necessarily the instant you need it. What group classes add that private sessions don't: a shared room, a consistent class structure to look forward to, and — for many people — the motivation of moving alongside others.
Cost follows the same logic: more one-on-one time from an instructor costs more per session than a spot in a class. Align & Flow's exact rates are outside the scope of this post — see our full Pilates price guide for Markham and the GTA for current numbers. This trade-off between attention and cost is one of the practical factors worth weighing alongside the other studio features covered in our guide to choosing a Pilates studio.
Who should start with private Pilates?
Private sessions are the more cautious, more tailored starting point in a few specific situations.
You have a diagnosed condition or a recent injury. If you have back pain, a joint issue, or another musculoskeletal condition, your instructor needs to know the specifics of your situation and adapt exercises accordingly — something that's far easier to do one-on-one than in a room of six people doing the same sequence. Canada's Get Active Questionnaire, a pre-screening tool developed by the Canadian Society for Exercise Physiology (CSEP), recommends that anyone who has been told by a health care provider to avoid or modify certain activities, or who has a medical condition that may affect their ability to be active, get guidance from a health care provider or a qualified exercise professional before changing their activity level (CSEP, Get Active Questionnaire, 2021). We adapt sessions to what a client tells us and work alongside your health care provider — we don't diagnose or treat medical conditions. If you're managing chronic lower back pain specifically, our guide on Pilates for lower back pain covers what the evidence says and how to start safely.
You're pregnant or in the postpartum period. Pregnancy and the months after birth both call for a program built around what your body is doing at that particular stage, which is easiest to deliver one-on-one. See when you can start Pilates after giving birth for guidance specific to vaginal birth and C-section recovery.
You have a specific, individual goal. If you want to work on one particular issue — a postural habit, a strength imbalance, preparing for a specific event — private sessions let the whole hour be built around that goal instead of a general class sequence. A posture assessment is often the starting point here: it gives you and your instructor a shared baseline to build a plan from.
You're brand new to Pilates and want to learn the fundamentals at your own pace. Private sessions aren't required to start — many beginners do perfectly well in a group class from day one. If you're weighing that decision, our guide on Pilates for beginners walks through what to expect either way.
Is private Pilates worth the extra cost?
There isn't a universal answer — it depends on what you're trying to get out of your sessions. Private Pilates tends to be worth the added cost when you have a specific issue to work through (an injury, a postural pattern, a pregnancy-related consideration) where individualized attention shortens the learning curve, or when your schedule only allows for one or two sessions a week and you want each one fully tailored. It matters less once you've learned the fundamentals and are working toward general strength and mobility — at that point, a group class delivers most of the same movements at a lower cost per session.
For exact current rates across private, semi-private, and group formats, see our 2026 price guide to Pilates in Markham and the GTA, which breaks down what's included at each level. Align & Flow's own current rates are listed in that guide too.
What is semi-private (duet) or small-group Pilates?
Between fully private and a full class sits a middle tier, usually called semi-private, duet, or small-group Pilates. The idea is the same across studios: an instructor works with a small number of people — often two to four — rather than one client or a full room.
This format keeps more of a private session's individual attention (an instructor watching two or four people can still catch and correct form issues quickly) while sharing the instructor's time, and typically the cost, across the group. It also suits people who want to bring a friend, partner, or family member along, since the pace can still flex more than it would in a larger class.
Can you combine private and group sessions?
Yes, and for many clients this is the most practical long-term plan. A common approach is one private session a week to work on individual goals or trouble spots, paired with one or two group classes to build overall practice and consistency at a lower total cost than an all-private schedule. Someone recovering from an injury might start entirely private, then shift toward a blend of private and group sessions as their program becomes more general. Someone training for a specific goal might do the reverse — mostly group classes, with an occasional private session before a key event.
How does Align & Flow structure its sessions?
Align & Flow offers both individual and group formats so you can choose — or blend — what fits your body and your schedule:
Posture Assessment + 1:1 Pilates Intro (1 hr 15 min) — a starting point that pairs an assessment with an introductory private session.
Private 1:1 Pilates with Lead Instructor (1 hr) — a full private hour with the lead instructor.
Private 1:1 Pilates with Instructor (1 hr) — a full private hour with an instructor.
Small Group Pilates Class (55 min, drop-ins welcome) — our standard small-group format; drop-ins are welcome.
Private Group Sessions (1 hr, custom scheduling) — a private session scheduled at a time that works for you. It's semi-private: you bring one or two training partners, and the price is per person.
Reformer and mat equipment are both part of our programming. Which combination is right for you is exactly what we'll talk through if you reach out.
Choosing your format with us in Markham
If you're not sure whether private, small group, or a blend is the right fit, that's a normal starting question — not something you need to solve on your own first. Book a Posture Assessment + 1:1 Pilates Intro or reach out about our Private 1:1 Pilates with Instructor or Small Group Pilates Class (55 min, drop-ins welcome) options at our Markham studio, and we'll help you choose a starting format based on your goals, any conditions you're managing, and your schedule. You can book online whenever you're ready.
Frequently asked questions
How many people are in a small group Pilates class?
Align & Flow doesn't publish an exact class size for the Small Group Pilates Class, so reach out to us directly to confirm what to expect for a specific session.
Can I do both private and group Pilates in the same week?
Yes — many clients build a weekly practice around one private session plus one or two group classes, which is one of the more common blended plans (see "Can you combine private and group sessions?" above).
Do beginners need to start with private lessons?
No. Group classes are a fine starting point for most beginners; private sessions are more of a consideration if you have a condition, an injury, or a specific goal you want the whole session built around. Our guide on what to know before your first class covers what your first session will actually involve.
Is private Pilates necessary if I have a health condition, I'm pregnant, or I'm postpartum?
Not strictly necessary, but it's usually the more cautious starting point, since your instructor can adapt the entire session to your specific situation from the first minute. For condition-specific guidance, see our posts on managing chronic back pain with Pilates and returning to Pilates after birth.
What's the difference between semi-private and a small group class?
They're often similar in practice; the general distinction is size — semi-private (or duet) usually means an instructor working with just two people, while a small group is somewhat larger. See "What is semi-private (duet) or small-group Pilates?" above for more detail.
