The core philosophy

When taught and applied properly, Pilates has proven itself to be an extremely effective and safe method of exercise for over 80 years. Chris is a purist, uses the original equipment and teaches the Authentic Pilates method, as taught by Joe Pilates. Each movement during the training session is initialized by the core muscle group (including the abdominal region, inner thighs and glutes) in order to protect, stabilize and lengthen the spine.

S6 Fitness is a system used by Chris and his staff. The following principles are steps in the system geared toward achieving the highest level of functional fitness. Whether in class or a private session, each client will work at his or her level and receive the personal attention needed to succeed.

Stability The ability to control joint integrity throughout the body. To keep the body safe and to maximize performance, all joints must be centered. This is the most important aspect of training.

Stamina The ability to maintain joint integrity for an extended period of time.

Stretch The ability to move throughout a full range of motion while maintaining joint integrity.

Strength The ability to move against resistance while maintaining joint integrity.

Speed The ability to move dynamically while maintaining joint integrity.

Synergy When using the body as a whole produces a greater result than using individual parts of the body.


Chris and his team provide individual attention and unparalleled quality training.

Carrie started working as a graphic designer after college and within a few years, even though she loved the profession, she learned she had too much energy to sit in an office all day. Having always been passionate about health and fitness, she decided to learn more about the human body and help people who are suffering in those desk chairs just like she was!

Cassie NevittPilates Instructor
Cassie Nevitt began her training in authentic Pilates in 2002. A former gymnast, she suffered chronic low back and neck pain for years. After doctors’ visits and physical therapy proved unsuccessful, she was thrilled to find that her Pilates practice stabilized her back and neck, leaving her pain-free. After training with a variety of Romana’s Pilates certified instructors across the country, Cassie moved to New York to train full-time at True Pilates New York, under the direction of Romana Kryzanowska and her daughter, Sari Mejia-Santo. She achieved her certification in February 2007, and has taught in St. Louis, MO, Fort Collins, CO, Chicago, IL, and is pleased to be settled here in sunny San Diego, CA. She feels tremendous gratitude for the ways Pilates has enriched all aspects of her life, and thrives on helping her students achieve benefits above and beyond their expectations. Cassie loves to hike, ski, surf, and enjoy the beauty of nature. She lives with her husband and two dogs in Clairemont.
