A live anatomical reference — 43 muscles on the interactive plate. Hover any group to identify; click to open its prescription — function, clinical pattern, and the classical Pilates exercises that recruit it. Toggle the layer to surface the deep core — transversus abdominis, the diaphragm and the multifidi — that most platforms hide. The complete muscle atlas follows below.
