Barre vs reformer Pilates: which should you book?

Short answer: Book reformer Pilates for small classes on a machine whose springs can make each movement easier or harder; Pilates also has the stronger evidence for chronic low back pain, though most of it is of low to moderate quality. Book barre for a bigger group class of small, high-repetition moves with light weights. Prices overlap: a drop-in costs $25 to $52 at Club Pilates and $25 to $40 at Pure Barre, and both chains offer a free first class. If you are injured, get assessed before either.

These two get compared because they fill the same slot: a low-impact studio class, grip socks and a promise of lean muscles. Pure Barre says its method “leads to long, lean muscles”; Club Pilates sells its signature reformer class “for strength, length, and control”.

The real difference is the resistance. Reformer Pilates uses springs on a sliding carriage. Barre uses your bodyweight, light weights and many small repetitions, held until the muscles shake.

What happens in a reformer class and a barre class

Reformer Pilates puts you on “a sliding carriage attached to springs, straps, and pulleys”, and you can work “lying down, sitting, standing, or even kneeling” (Arizona State University’s reformer program). One maker’s studio reformer offers “up to 46 resistances” (Balanced Body), and Club Pilates says the springs and straps “increase or decrease the challenge”. Classes are small: Club Pilates studios are designed for “usually up to 12 people”.

Barre borrows from ballet: small, high-repetition movements at a barre, with light hand weights, a ball or a band. It is not all standing. Every Bar Method class ends with “core exercises on the floor”, and at Pure Barre “Your teacher will bring you a mat halfway through class.” Pure Barre studios are designed for “up to 26 people”. Our guide to what a barre class is like covers the experience.

Both are low-impact. The barre chains promise the shake: The Bar Method warns “You will shake in class and you will be sore after class”.

What the table shows:

• The low ends match. Both of the biggest chains start at $25 a class and offer a free first class.
• Reformer runs higher at the top. Club Pilates reaches $52, and the two independent reformer studios charge $46 and $48. Pure Barre tops out at $40, though Physique 57 in New York charges $44.
• Private sessions cost more. At Pilates Northwest, a session in a 4-pack costs $84 private and $58 per person as a duet, against $43 for a group class.
• Reformer is not harder to find. At the end of 2025, Club Pilates had 1,414 studios and Pure Barre, the biggest barre chain, 625 (Xponential Fitness, which owns both).

Check the terms before you sign: [solidcore]‘s memberships carry a 12-month commitment and Physique 57’s a 3-month minimum. Our guides on whether studio memberships are worth it and how to cancel one cover the traps.

Barre or reformer with an injury or back pain?

Get assessed first. Cleveland Clinic: “It’s especially important to talk to a doctor if you’re injured or recovering from surgery.” The Hospital for Special Surgery (HSS): “If you’re currently suffering from back pain, start by seeing a professional, if possible, to get a clinical assessment.”

Pilates has the larger evidence base for back pain:

• A review of 217 trials found “that Pilates, McKenzie therapy and functional restoration were more effective than other types of exercise treatment for reducing pain intensity and functional limitations” (Hayden and colleagues, 2021).
• A Cochrane review found “low to moderate quality evidence that Pilates is more effective than minimal intervention for pain and disability”, but “no conclusive evidence that it is superior to other forms of exercises” (Yamato and colleagues, 2015).
• In a trial of 86 patients, equipment-based Pilates beat mat Pilates at six months for disability and fear of movement, but not for pain (da Luz and colleagues, 2014).

Physical therapists use the reformer. University of Utah Health runs a Pilates clinic where its “physical therapists are trained in movement analysis within the Pilates method”, and HSS’s Midtown rehabilitation center lists a Pilates Reformer among its equipment.

Barre can be adapted too. The Bar Method publishes modifications “intelligently designed with physical therapists” for people healing from surgery or an injury, and a Cleveland Clinic physical therapist says “There’s a rehabilitative aspect to barre as well.” But barre has barely been studied: three small studies, on urinary incontinence, older women and Parkinson disease. No trial has compared reformer Pilates with barre.

With an injury, Club Pilates suggests starting with “private training sessions that are tailored to your personal needs”. Our guide to massage vs physical therapy covers when you need an assessment first.

Does barre or reformer Pilates build strength or cardio?

Strength: neither is heavy resistance training, and the evidence is mixed.

• In older adults, a review of 24 trials found “low quality evidence that Pilates did not significantly improve muscle strength compared to the control group” (Oliveira and colleagues, 2024).
• In a small trial, eight weeks of reformer Pilates “increases muscle strength and endurance” in overweight and obese women (Gökalp and colleagues, 2025).
• In women aged 60 to 80, Pilates did better for isometric hip and trunk extension strength, and resistance training did better for isokinetic strength (Carrasco-Poyatos and colleagues, 2019).

Barre has no strength trial, though some formats add weights: Pure Barre Define fuses barre “with weight-based strength training”. Cleveland Clinic advises adding resistance training and aerobic exercise each week.

Cardio: Pilates is light exercise. The Compendium of Physical Activities lists “Pilates, general” at 2.8 METs, and a pooled analysis found that Pilates “appears to elicit light-to-moderate metabolic intensity” (Vitor and colleagues, 2026). Nobody has measured barre’s cardio load. Both chains sell faster formats: Pure Barre Empower mixes barre with high-intensity interval training to raise your heart rate.

What about Lagree, or [solidcore]?

Lagree runs on the Megaformer, and Lagree Fitness says: “It is not a Pilates Reformer.” Its inventor describes the machines as an evolution of the reformer: “everything else in my machines was an evolution from the original.” The method uses “a very slow tempo”, and “Resting is not allowed during each set.” No Lagree trial appears in PubMed.

[solidcore] sits nearby: “[solidcore] is not Pilates, but it is a strength-training workout that uses a Pilates-inspired reformer.” Our guides on what a Megaformer class is like and reformer Pilates vs Lagree cover the differences.

Which should you book first, barre or reformer?

• Reformer if you want small classes, a machine that can make movements easier as well as harder, or Pilates for back pain after an assessment.
• Barre if you want a bigger group class to music, built on small, high-repetition moves.
• Both, if you are unsure: the first class is free at Club Pilates and at participating Pure Barre studios.

FAQ: barre and reformer Pilates

Will barre or reformer Pilates give me long, lean muscles? Both chains promise it, but no trial has tested it. Training can change a muscle’s shape: muscle growth from resistance training “has been reported to occur nonuniformly along the length of the muscle” (Wakahara and colleagues, 2013), and fascicles grew 12% longer after eccentric training in another study (Franchi and colleagues, 2014).

Do I need grip socks for barre and reformer Pilates? Usually. Club Pilates, Pure Barre and Physique 57 require them and sell them at the studio. At [solidcore], “Our workout is done barefoot and grip socks are optional.”

Is barre good cardio? Nobody has measured it. Pilates is light exercise, at 2.8 METs for “Pilates, general” in the Compendium of Physical Activities, and both chains sell faster formats, such as Pure Barre Empower, designed to raise your heart rate.

Which is better for beginners, barre or reformer Pilates? Both of the biggest chains start beginners with a free intro class. On a reformer, Cleveland Clinic says “it’s important to work with an instructor to learn the correct alignment”. Some independent studios set a first step: Ballet Austin’s Pilates center asks new clients to get approval before joining group classes, and sells a package of intro duets.

How much does a reformer Pilates class cost? On October 26, 2026, a drop-in cost $25 to $52 at Club Pilates depending on location, $40 at [solidcore] in Santa Monica, and $46 and $48 at two independent studios. A private session cost $84 in a 4-pack at Pilates Northwest.

The bottom line on barre vs reformer

Reformer Pilates gives you springs, a smaller room and the larger evidence base for back pain. Barre gives you a bigger group class of small, high-repetition moves. Prices overlap at the low end, both of the biggest chains offer a free first class, and neither replaces resistance training for strength. If you are injured, get assessed before you book either.
