What is the first part of the Pilates System that Joseph Pilates created?

The first part of the Pilates system that Joseph Pilates developed is the Mat. Joseph Pilates originally conceptualized his exercise system as a series of movements performed on the mat, utilizing body weight for resistance and focusing on principles such as control, precision, and breath. The mat exercises were foundational to his training philosophy, emphasizing core strength, flexibility, and overall body awareness without relying on any apparatus.

Over time, Pilates expanded his system to include various pieces of equipment like the Reformer, Cadillac, and Chair, each designed to complement the mat work by providing additional resistance and support. However, the mat remains central to the practice, as it fosters an understanding of the fundamentals and principles that underpin all Pilates movements. This foundational aspect is crucial for practitioners to build upon as they progress to using the equipment.
