What is the difference between reformer pilates and mat pilates?

TL;DR: Mat pilates is done on the floor, while the reformer uses a machine with springs and straps, which allows a greater range of motion and stronger muscle activation.

The short answer

Mat pilates is done on the floor, while the reformer uses a machine with springs and straps, which allows a greater range of motion and stronger muscle activation.

In more detail

Classic mat pilates works on a mat, where your own body is the resistance. Reformer pilates adds a machine that gives you resistance and support at the same time.

The practical differences

Mat (classic) Reformer
Resistance Body weight Springs (3–4 levels)
Assistance — The machine can support you through the movement
Range of motion Limited Greater (sliding carriage, straps)
Learning curve Faster Longer (more moving parts)
Price per class Lower Higher

Which one should you pick?

  • You are starting out and want a low-stakes introduction: mat pilates
  • You have an injury or a specific goal (posture, core strength): reformer
  • You want visible results sooner: reformer

Reformer pilates adapts to every level — from complete beginners to athletes.
