What is LES MILLS REFORMER™?

What is LES MILLS REFORMER and how does it work? 

LES MILLS REFORMER is a 45-minute Reformer Pilates workout that combines traditional Pilates principles with music-driven, choreographed training. 

Each class is organized around four core training blocks – Foundation, Front, Back, and Stretch – that guide the session from start to finish. 

Training uses controlled movement patterns with time under tension and pulses to develop strength, stability, mobility, and control. 

Participants choose their own resistance using the reformer spring system, allowing them to adjust intensity for different experience levels.

What makes LES MILLS REFORMER different from traditional Reformer Pilates? 

LES MILLS REFORMER replaces the variability of traditional Reformer Pilates with a structured format designed for consistency across classes and locations. 

The playlist drives timing, rhythm, and movement quality throughout each session, shaping how the workout is performed rather than acting as background music. 

The Instructor role is also different. Instructors coach while demonstrating approximately 70–80% of the movements from a reformer bed at the front of the room, using visual and verbal cueing to guide technique and flow. 

Together, the choreography, music, and coaching create a unified, rhythm-led training experience distinct from traditional Reformer Pilates.

How does LES MILLS REFORMER training work?

LES MILLS REFORMER training follows the Les Mills Signature training journey, with all learning delivered on Reformer equipment to ensure a fully practical, hands-on experience.

Participants control resistance using reformer springs, with built-in modifications for all levels.

This allows beginners and experienced participants to train within the same structured class format.
