Hi, I'm Audrey Laurelton, owner of Equilibrium Pilates in Montclair, NJ. I'm here for About.com to go over the different principles in Pilates. The central tenants of Pilates are concentration, control, centering, precision, breath, and flow. Pilates is truly a body and mind form of exercise. You’ll find the more that you concentrate on the exercise at hand and on the targeted muscles, the more that you’ll feel it and the quicker results you'll get. Joseph Pilates placed a great deal of emphasis on control. In fact the original name of Pilates was Contrology. Each exercise is to be performed with the utmost control. Centering is the focus on the core or Pilates’ Powerhouse. The Powerhouse includes the abdominal, lower back, buttock, and hip muscles. Each exercise in Pilates is initiated from the Powerhouse. Precision pertains to performing each exercise with accuracy as each exercise has a specific purpose as well as each part of the body within the exercise. Breathing is an integral part of Pilates. The extended exhalations force stale air out of the lungs while the extended inhalations bring fresh oxygen to the blood, rejuvenating the body.Each exercise in Pilates should flow into the next, keeping the body in constant motion and aiding in dynamic stretching. There’s also a certain amount of detail focused on the grace and quality of the movement Thank you for watching and for more information, go to: health.about.com.
