Reformer Pilates vs Transformer Pilates: What’s the Difference?

In short: reformer Pilates is the umbrella term for machine-based Pilates on a sprung carriage; Transformer Pilates is KARVE’s own signature method on a machine designed in-house — the same low-impact foundations, taken to a higher intensity in a 50-minute class.

Reformer Pilates is the workout category: low-impact, full-body training on a spring-resistance machine. Transformer Pilates is KARVE’s signature take on it — a 50-minute class that layers strength training and mindful movement over the reformer fundamentals. Here’s how they differ, and how to choose.

What is reformer Pilates?

A reformer is a resistance machine built around springs, straps and a sliding carriage. Because the resistance is controlled and adjustable, reformer Pilates lets you work deeply — building strength, core stability, posture and flexibility — while staying gentle on the joints. That combination is why it suits almost every fitness level, from complete beginners to experienced athletes.

What is Transformer Pilates?

Transformer Pilates is KARVE’s signature 50-minute workout, performed on the KARVE Transformer — a resistance machine designed in-house and found only in KARVE clubs. Each class takes the reformer foundation and adds strength-led sequencing and controlled, high-intensity work, finishing with breathwork to reset. You can read more on our Transformer Pilates page.

The key differences at a glance

— The machine: reformer Pilates uses a classic reformer; Transformer Pilates runs on the custom-built KARVE Transformer.

— The programming: a typical reformer class centres on Pilates fundamentals; a Transformer class layers strength training and mindful movement over them in one 50-minute format.

— The setting: Transformer Pilates is taught only at KARVE, in small groups led by instructors certified in the KARVE method.

— The finish: every Transformer class ends with breathwork — a full reset before you step back into the day.

Which is right for you?

If you want low-impact, full-body training, both will serve you well — Transformer Pilates simply concentrates more strength work into the same 50 minutes. Beginners are welcome in either: resistance scales to your level, and trainers guide every movement. If you’re brand new, arrive a few minutes early for a short introduction to the machine.

Trying it in London

KARVE teaches Transformer Pilates at three London studios — Kensington, Chelsea and Victoria. Start with the reformer Pilates overview, read the first-timer guide before your first visit, find your nearest studio on the clubs page, and compare memberships and class packs when you’re ready to book.

Quick answers

Can beginners join a Transformer Pilates class? Yes — the springs scale the resistance to you, classes mix first-timers with regulars, and every class is led by an instructor certified in the method.

What should I wear? Tight, comfortable clothes and grip socks — socks are required on the machine and available to buy in studio.

Which should I choose? If you want classical reformer pacing, a traditional studio suits you; if you want reformer foundations with a strength-and-cardio push, that’s exactly what the Transformer format was built for — try one class of each and compare how you feel at minute fifty.

Quick pros and cons

Reformer Pilates

• Pros: widely available across London, a classical repertoire refined over decades, and a gentle entry point for rehabilitation-focused work.
• Cons: intensity varies enormously between studios, and classical pacing can undershoot people training for strength.

Transformer Pilates at KARVE

• Pros: a full-body, 50-minute workout every session, a wider spring-resistance range, and one consistent method taught by KARVE-certified instructors.
• Cons: the Transformer is proprietary — you’ll only find it at KARVE clubs — and honest warning: your first class is hard.
