If a friend keeps raving about her Megaformer class and you are quietly wondering what is lagree, this guide is for you. It is one of the fastest growing workouts in boutique fitness, and it looks deceptively calm until you actually try it and your legs start to shake. Lagree is low-impact like Pilates but far more intense, built to fatigue your muscles slowly and completely. In our Henderson studio, members ask us what is lagree almost as often as they ask about the Reformer, usually after seeing it pop up on their feed. Let us clear up exactly what it is, where it came from, and whether it belongs in your week.
What is Lagree? A simple definition
Here is the short version. Lagree is a high-intensity, low-impact strength workout performed on a spring-loaded machine called the Megaformer. You move slowly and deliberately against heavy resistance, holding each exercise in its hardest range so your muscles work with almost no rest. The result is a deep, shaking burn that builds strength and endurance without stressing your joints the way running or jumping does.
The method was created by trainer Sebastien Lagree, who started with Pilates principles and then engineered something far more demanding. So when people ask what is lagree, the cleanest answer is this: Pilates DNA, cranked to a much higher intensity on a purpose-built machine. It keeps the control and the low impact, but trades the calm, moderate pace for constant, unrelenting muscular work.
The name causes some confusion, since Lagree is both a person and a method, and the machines have carried different names over the years, from the Megaformer to newer models. For a beginner, none of that history matters much. What matters is that the class is slow, heavy, and low-impact, and that it will find muscles you forgot you owned within the first ten minutes.
What is Lagree built on?
To really grasp what is lagree, it helps to look at its two pillars: the Megaformer and the tempo. Together they turn small, precise movements into a full-body challenge that leaves almost no room to coast. Take either one away and the workout loses the quality that makes it so effective, and so humbling, in the first place.
The Megaformer machine
The Megaformer looks like a Pilates Reformer that spent a year in the gym. It uses adjustable springs and moving platforms so you can load nearly any muscle group, from your inner thighs to your obliques to your shoulders. Because the resistance is smooth and spring-based, there is no jarring impact, just constant, controlled tension. That machine is the piece of equipment that makes what is lagree so distinctive compared to a mat class. The platforms glide on a track, so you are constantly resisting the pull of the springs in both directions, which is why even a slow, small movement can feel enormous by the tenth rep of a long and very controlled working set.
So what is lagree like in practice?
Expect long, slow reps counted out loud, moves held for 60 seconds or more, and a lot of time under tension. Classes usually run 40 to 50 minutes and move from one muscle group to the next with barely a pause. According to a 2023 systematic review on the NIH’s PubMed Central, Pilates-style core work can improve core muscle strength measured by muscle thickness, and this style leans hard on that same deep core control while adding serious load.
The sensation is what surprises people most when they first learn what is lagree. There is no bouncing, no sprinting, no crashing weights, yet your muscles burn as if you had done all three. That slow, shaking quality is the whole point, because time under tension is what drives the strength and endurance gains. If you have only ever done fast, high-impact workouts, the stillness of it can feel strange for a class or two before it clicks.

What is Lagree good for?
People love what is lagree able to deliver in a short session: fast, full-body strength and a serious burn without pounding their joints. Regular practice tends to build muscular endurance, better posture, and that lean, toned look many women are after. Because every rep is slow and controlled, it also builds a kind of body awareness that carries over into every other class you take. Some people use it as their main strength work, while others fold it in once a week to complement Reformer or Mat sessions. There is no single right way to use it, only the way that keeps you consistent and feeling good in your own body week after week.
- Low-impact strength that spares your knees, hips, and back.
- Muscular endurance built from long holds under heavy tension.
- A quick, efficient full-body burn in a 40 to 50 minute class.
- Better core control, posture, and balance over regular practice.
Is Lagree right for you?
Lagree suits people who want intensity and do not mind feeling humbled by a workout. If you are brand new to fitness, pregnant, or returning from an injury, mention it up front so an instructor can modify the moves or steer you toward a gentler start. The encouraging thing in the what is lagree conversation is that the low impact makes it accessible to a wide range of bodies, even when the intensity runs high.
Our instructors usually start newcomers slow, with lighter spring loads and more rest between moves, then build from there once your form is solid. We would much rather you finish your first class curious and wanting more than walk out feeling defeated. That patient on-ramp is exactly how a beginner turns into someone who craves the burn a few weeks later. It also protects your body, since good form under heavy tension is what keeps a hard workout from becoming a sore lower back.
It is worth being honest about the intensity when you are deciding what is lagree going to ask of you. This is not a gentle stretch class, and it should not pretend to be. You will sweat, your legs will quiver, and you may need to pause and shake out a muscle mid-set. All of that is normal and expected, and none of it means you are doing it wrong or that you are not fit enough to be there.

What is Lagree, in one sentence?
Lagree is a high-intensity, low-impact strength workout done on a spring-loaded Megaformer machine, where you move slowly against heavy resistance to fatigue your muscles with almost no rest. It grew out of Pilates and shares its core focus, but pushes intensity and time under tension much further.
Is Lagree the same as Pilates?
No. Lagree is built on Pilates principles like core control and low impact, but it uses the Megaformer, heavier springs, and a slower tempo to reach muscle fatigue faster. Think of it as Pilates turned up in intensity rather than a different family of movement altogether.
What is Lagree good for?
It is good for building low-impact strength, muscular endurance, and a lean, toned look in a short, efficient class. Because there is no jumping or pounding, it spares your joints while challenging your whole body. Many people also enjoy the mental focus that the slow, deliberate pace demands of them.
Do I need to be fit to try Lagree?
No. The intensity is high, but the low impact and adjustable springs make it scalable for many fitness levels. Tell your instructor if you are a beginner or managing an injury, and expect to modify freely. Your very first class should feel hard, but never discouraging or unsafe.
Does RÓS Pilates offer Lagree classes?
We do not run a trademarked Lagree program. Our Reformer, Hot Pilates, and Lift & Sculpt classes deliver a similar low-impact, high-intensity feeling of strength and burn. Our instructors are happy to help you pick the class that matches what first drew you to Lagree, so you feel at home fast.
How long is a Lagree class?
A typical Lagree class runs about 40 to 50 minutes. That is enough time for a full-body sequence of long, slow reps with little rest, which is why it feels so demanding despite the short clock. Expect to work almost continuously from the warm-up through to the final stretch.
