Not every Reformer class is the same. The machines vary by manufacturer, the programming ranges from classical to contemporary to large group formats, and some carriage based classes, like Lagree on a Megaformer, are not Pilates at all. This guide explains how the equipment, spring tension, and method differ, and why those differences matter for anyone thinking about becoming Reformer certified.
Walk into a Pilates studio, health club, or boutique fitness facility and you may see a room filled with machines that look fairly similar: a sliding carriage, springs, platforms, straps, bars, and plenty of places to put your hands and feet.
But look a little closer.
Not every Reformer is the same. Not every class follows the same approach. And some of those machines are not Pilates Reformers at all.
For someone thinking about becoming Reformer certified, understanding those differences is part of understanding just how much there is to learn.
A Reformer is more than a machine with springs
The Pilates Reformer is built around a sliding carriage that moves along a frame and uses springs to create tension. Depending on the exercise, those springs can provide resistance, assistance, stability, or instability.
That last part is important.
More spring tension does not automatically mean a harder or more advanced exercise. In some movements, heavier springs increase resistance. In others, they provide additional support and stability. Reduce that support and the client may suddenly have to control much more of the movement independently.
Learning to select springs based on the exercise, the client, and the intended outcome is one of the skills that separates simply knowing a few Reformer exercises from understanding how to teach them.
Even Pilates Reformers can be very different
If you have used more than one brand of Reformer, you may have already noticed this.
A red spring is not a universal measurement.
Manufacturers use different spring systems and tensions, and Reformers can vary in carriage height and width, footbar design, rope or strap systems, gearbar positions, headrests, shoulder blocks, and adjustment options.
Some contemporary Reformers also accommodate jump boards, boxes, platform extenders, towers, and other accessories that dramatically expand the exercise possibilities.
That means memorizing "two springs" is not enough. An instructor needs to understand what those springs are doing, how the equipment in front of them operates, and how the setup affects the person performing the exercise.
Classical and contemporary Reformer Pilates can look different, too
Equipment is only part of the story. Programming varies as well.
Classical Reformer Pilates is rooted in Joseph Pilates' established repertoire and sequence. Exercise order, transitions, precision, control, and flow are important parts of the experience. Exercises are connected rather than simply selected individually because they target a particular muscle group.
Contemporary Reformer Pilates retains the foundations of the method while allowing greater flexibility. An instructor may alter the sequence, introduce preparatory movements, use props, modify exercises, or select movements according to the needs and goals of a particular client.
Neither approach eliminates the need to understand the fundamentals.
In fact, knowing the traditional repertoire and the purpose behind the exercises gives instructors a stronger foundation for deciding when and why to adapt them.
And then there is Lagree
This is where things get particularly interesting.
A Megaformer has a moving carriage and springs. From across the room, someone unfamiliar with either method might reasonably assume they are looking at a variation of a Pilates Reformer.
They are not the same thing.
Lagree is a separate exercise method created by Sebastien Lagree, and the Megaformer is equipment specifically designed for that method. Lagree places significant emphasis on variables such as slow tempo, muscular tension, duration, transitions, and muscular endurance.
The equipment reflects those goals. Megaformers include large front and rear platforms, multiple hand and foot positions, specialized bars and handles, and a spring configuration designed around Lagree programming.
Both workouts may be challenging. Both may involve springs and a moving carriage. But learning to teach Pilates Reformer does not automatically qualify someone to teach Lagree, and Lagree training does not replace an education in the Pilates Reformer repertoire.
The distinction is a good reminder of something future instructors should understand early: the machine does not define the method.
Group Reformer adds another layer
Reformer Pilates has also expanded beyond small studio sessions.
Today, instructors may find themselves teaching group Reformer classes in boutique studios, Pilates franchises, and larger fitness facilities. Instead of working with one or two clients, an instructor might have an entire room moving through the same sequence.
That requires another set of teaching skills.
How do you get everyone safely into the starting position? When should springs change? Can participants make that change independently? How do you scan the room while continuing to teach? What happens when one person needs a modification? How do you maintain flow without rushing people onto a moving carriage?
Knowing the exercises is only the beginning.
That is what makes learning Reformer so interesting
The deeper you get into Reformer Pilates, the more you realize how many variables an instructor is managing at once.
You are selecting exercises and spring tension. You are watching alignment and carriage control. You are deciding when to cue and when to allow the client to move independently. You are adjusting footbars, headrests, straps, ropes, and carriage positions. You are modifying exercises for different bodies and abilities while still considering how one exercise prepares the client for the next.
And you are doing all of that while keeping the session moving safely and intentionally.
The Reformer can challenge strength, stability, mobility, coordination, control, muscular endurance, and even cardiovascular fitness depending on how it is used. Springs can resist movement in one exercise and assist it in another. Small equipment changes can completely alter how an exercise feels.
That is also why Reformer Pilates is difficult to fully understand by simply taking classes or collecting exercises from social media.
There is a method behind the movement.
Ready to move from participant to instructor?
If you already enjoy Reformer Pilates, becoming certified gives you the opportunity to understand what is happening behind the workout.
Instead of simply knowing what exercise comes next, you can begin to understand why it comes next, how to teach it, how to select the appropriate spring tension, how to modify it for different clients, and how to build safe, effective Reformer sessions from start to finish.
The ISSA Reformer Pilates Certification takes you beyond experiencing the Reformer as a participant and teaches you how to use it as an instructor. You will explore the equipment, biomechanics, exercise repertoire, cueing, modifications, programming, safety, and professional skills needed to confidently work with a variety of clients.
