Pilates is a mind, body, and spirit practice that incorporates stability and mobility work primarily focused on using core (abdominal, back, and butt) muscles. Those new to Pilates can begin with a home practice. Mat Pilates videos and books are widely available. A home practice is safe for anyone free of injury or chronic back pain. Beginners may also benefit from taking introductory Mat or Reformer Pilates classes with a trained Pilates teacher. Even those taking Pilates classes outside the home will benefit significantly from doing Pilates at home; in fact, many Pilates teachers encourage homework between classes.
