I repeatedly get asked about what exactly Pilates is when people discover that I'm a certified instructor. Yes, it does work your core, but your entire body will also get a work out as well. No, it is not a form of Yoga , but is similar, as both are a wonderful form of exercise.
Pilates was created by Joseph Pilates in the 1920's for the purpose of rehabilitation. Dancers were the first to use Pilates as a way to strengthen their bodies and to heal their injuries.
Pilates focuses on improving flexibility, strength and body awareness. Yes, the core is a focus, but not just the superficial "six-pack" muscles of the abs, but rather, the more important deep core muscles that assist us in everyday movement, alignment and posture. In developing strength, body awareness and better posture through Pilates, one can alleviate many of the common aches and pains of the back, hips and knees and the problems associated with a weak (or too strong) pelvic floor.
If this has piqued your interest in the power (and fun) of Pilates, look into joining a class or a private or semi private session, because only then will you realize the life changing benefits of Pilates.
