The Key Principles of the classical Pilates Method
Pilates training is intended to improve general body flexibility and health by emphasising "core" (truncal) strength, posture, and coordination of breathing with movement.
Centring is considered to be the main focus of the Pilates Method. The "centre" refers to the core of the body and is usually known as the "powerhouse". In today's Pilates training it is believed that centring is involved mainly in the full activation of the core stability muscles such as Transversus Abdominis.
Concentration
it is the mind that guides the body; hence focused concentration is necessary when carrying out Pilates exercises.
Control
one must be in control of the movements performed.
Precision
A common saying in the world of Pilates that illustrates this is, "It is not how many you do, but how you do it".
Breath
all exercises should be done with rhythmical breathing.
Flow
flowing succession of one exercise to another during a Pilates session. (Siler 2000)
