The concept of the Pilates Powerhouse has been given multiple meanings. Some use it to refer to the abdominal part of the body. While others use imaginative cueing to explain how to connect to a particular muscle group. We think Romana Kryzanowska, Joseph Pilates' legendary student, meant for it to be a dynamic approach to life. The Powerhouse is a set of actions that produce correct posture. Correct posture leads to spinal health which is dependent on spinal flexibility and mobility. The Powerhouse isn't just the area that you work on to strengthening and stretching in a Pilates session, but also the actions that build on each other in all planes of movement, and include opposition and concentration. The actions are specific for working the area that each level is ready to engage.
