• Pilates has introduced me to the concept of core strengh. It improved the alignment of my spinal column, which in turn relieved or eliminated alot of my neck, shoulder and lower back discomfort. As you attempt each exercise you can feel your body as it becomes aware and attempts to adjust to each move.
  • Most of my life my idea of exercise was totally aerobic... running, biking etc. It was out of curiosity I signed up for a private Pilates session about three years ago with Sonia. I was blown away by the changes in my body and how much leaner I have become. I continue to hike the beautiful mountain trails in Phoenix and am so much physically stronger due to my Pilates training. I highly recommend this to anyone who is interesting in improving their core strength, posture and overall health.
  • I was looking for an exercise program that would help my total body but with minimal impact on my joints. Pilates helped in developing and strengthening my core which in turn has helped me in my daily activities. It has helped to increase my body awareness in posture and flexibility.

  • Remember, it is not you adjusting to the exercises, it is the exercises themselves that must adjust to you. The pictures serve as guidelines, not what you are expected to copy. The bottom line is to feel the movement in correct the muscles groups and see physical change in your body.
