Have you ever tried Pilates?

Pilates was developed by Joseph Pilates in the early 20th Century.  "Pilates called his method Contrology, because he believed his method uses the mind to control the muscles," says Wikipedia.  "The program focuses on the core postural muscles which help keep the body balanced and which are essential to providing support for the spine. In particular, Pilates exercises teach awareness of breath and alignment of the spine, and aim to strengthen the deep torso muscles."
