The "powerhouse" or core of the body is the center of all movement. Learn how to stabilize the body by initiating all movement from the center. This premise is the heart of the method. 

Every movement in Pilates is controlled. It is this attention to form that demands the body and mind to focus, working as one. 

The mind is required to concentrate to perform each exercise with control. Exercises are not repeated excessively and, therefore, this high level of concentration is required fully and accurately in order to complete each movement. There is no excess or "auto pilot" where the mind can wander, as in other forms of exercise. 

Each exercise has its own rhythm and transition into the next exercise. The work is designed to flow as a whole, working the body completly from start to finish. Every session should progress in this manner. 

Breath is essential in the work of Joseph Pilates. His emaphasis on exhalation is crucial in his work as he believed you need to squeeze the air out of the lungs like the wringing of a wet cloth. By doing so, you cleanse the lungs by pushing stale air out and filling them back again with a new breathe. His attention to breath in each exercise is tantamount to accurate execution of the exercise. 

Correct alignment and stabilizing the pelvis is an important aspect of Pilates practice. Faulty alignment negatively affects your abilities to concentrate, center, breath properly, maintain correct posture, and achieve balanced, efficient,  movement. Pilates is precise, controlled movement where every detail is important. Every exercise must be practiced with attention to alignment, form, and breath. It is with precision that you are only truly able to understand the work.
