Have you heard of the Pilates reformer? If it sounds like something straight out of a Victorian-era punishment chamber, rest assured — it is actually one of the most effective and versatile pieces of fitness equipment ever created.
If you have ever stepped inside a Pilates studio or scrolled past a class on social media, you have probably noticed a curious contraption featuring leather straps, springs, and a sliding platform. Those machines are reformers, and they have been transforming the way people train their bodies for decades.
The reformer is one of several large pieces of equipment found in a traditional Pilates studio — alongside the barrel, the trapeze table, and the Pilates chair. Of all these, the reformer is widely considered the most effective way to practice the Pilates method.
As Joseph Pilates himself once noted, you can exercise without machines — but that is not quite as effective. The reformer is uniquely designed to either resist or assist your movement during a workout, making it adaptable no matter where you are or what your body needs.
In this guide, we will answer two essential questions: What exactly is a reformer, and why is it so beneficial?
The Pilates Reformer Machine
The reformer is among the original pieces of equipment designed by Joseph Pilates, the man who developed the Pilates method. Thanks to the growing success of reformer-based group classes, it has become arguably the most iconic apparatus in the Pilates world.
If you are not yet familiar with the reformer, here is a straightforward breakdown of what you are looking at and how it all comes together.
Pilates Reformer — What Is It?
At first glance, the reformer resembles a bed-sized rectangular frame. Depending on whether it is a classical or contemporary model, the frame may be made from either metal or wood.
Sitting on top of the frame is a padded platform known as the carriage. This carriage is attached to hidden corners and can slide back and forth along the length of the frame freely.
Design elements like this make the smooth execution of exercises possible, helping practitioners achieve their "flow" during a Pilates session.
At one end of the reformer sits the foot bar. This is adjustable and can be moved to change the use of the reformer for different heights. The foot bar can also be quickly lowered or raised for specific exercises.
The carriage is attached to the rest of the reformer through a series of springs in a range of spring tensions. These springs are only hooked on to the frame — not permanently fixed — and can be easily removed.
By adjusting the spring tension, the resistance produced by the reformer is altered. Some exercises are made either easier or more difficult. Interestingly, one light spring is often more challenging than several heavier ones.
At the opposite end of the frame are two long ropes with loop handles attached to pulleys. When it comes to the loop handles, there is usually an option of a small one and a large one. The smaller ones are intended for hands and the larger ones are designed for feet.
The reformer carriage has other features such as shoulder pads to stop you from sliding off when exerting force, and an adjustable headrest designed to make your experience on the reformer more comfortable.
Pilates Reformer — How Does It Work?
The reformer is a remarkably versatile piece of equipment that can be used for lying down, standing, kneeling, or even sitting exercises. Most exercises on the reformer involve some sort of pushing or pulling or gliding action. Other exercises involve keeping the carriage still while the tension of the springs works against you.
Another useful application of the reformer — and part of why it is so effective — is that it can be either assistive or resistive. In simple terms, this means that exercises can be made more or less challenging using this one machine.
What Does Reformer Pilates Do?
Are you wondering what exactly the Pilates reformer can do for you? If you are feeling a bit overwhelmed by this apparatus, that is perfectly normal. This ingenious piece of machinery has many features which make exercises varied, interesting, and above all, effective.
The Pilates Reformer Can Be Assistive
Consider an exercise like the "roll down." For instance, the roll-down involves the fluid movement of the spine from a vertical position to being moved through a rounded one. It is an exercise that mobilizes the spine and strengthens the stabilizers around it.
You can perform this on a mat without any equipment, but it is a pretty difficult exercise to do well without recruiting muscles or using the wrong strategies to help you cheat your way through it. On a reformer, however, you have the choice to hold on to the straps and add extra springs for support. This makes the exercise easier to execute.
So rather than challenging your movement, the reformer in this instance is actually helping you perform the movement correctly. In doing so, you are invited to activate the right muscles — the muscles intended to work in a specific exercise.
The Pilates reformer is supportive. The position on the reformer supports the weight of your body. Your muscles are not having to push you up against gravity directly, so you can truly relax into the movement.
The Pilates reformer can offer you more. The additional features of the reformer can also support you — the bar and the foot straps can support the weight of the leg while you do exercises that challenge the abdominals. For example, if you were to do the on-the-floor bicycle during Pilates and your legs were simply too heavy, the reformer can provide the support that removes that extra burden.
The reformer provides real-time feedback. The sensory feedback that you get from having the whole of your body resting on the reformer means that you are getting more information about the position of your core and pelvis, as well as how you are moving. Any habits that you may have formed of tilting your pelvis or holding your shoulders tense become tactile and visible, giving you a richer understanding of how your body moves.
The Pilates Reformer Is Challenging
The Pilates reformer setting can be altered by attaching a pulley and a moving carriage operating on spring resistance. By setting up the carriage with more spring resistance, you can create more sophisticated and demanding exercises — pushing your body further than mat work alone ever could.
The reformer can also be set up so that you have less stability on the moving carriage, and this can make exercises more challenging. For example, performing a plank on the reformer will make things harder because you need to remain steady on the springs as you hold yourself in position on the moving carriage.
The reformer works differently for standing exercises, such as a "Scooter." This is like a running movement where one leg is placed on the floor and the other on the reformer.
Instead of adding the movement, the leg extension piece of the exercise is resisted by the springs of the reformer. This means that, as well as teaching the body to move in the correct way, the force created by the reformer springs is also building strength in the leg and glutes.
