The practice
What Pilates-style movement is
Pilates works the muscles that hold you up: the deep abdominals, the pelvic floor, the small muscles along the spine, the glutes. It does that with slow, controlled movement and a steady breath, on a mat, one segment of the spine at a time.
The tempo is the method. A roll-up done in eight slow counts asks more of your core than twenty fast crunches, and it asks it politely. You feel exactly which part is working, and you never get to cheat with momentum.
Nouvelou's version is mat-based. No reformer, no studio, no springs. A mat, a bit of floor, and for some sessions a chair or a wall.
