About CoreSpring®
CoreSpring® began in 2019 with a simple question in a Pilates teacher training session: Why do we work with springs on the apparatus but when we go to the mat, we use bands? This led to an experiment with — and an experience of — direct spring resistance: a new, portable way to work with the body. What looked simple proved to be anything but: consistent testing revealed a method, not just a tool. That discovery led to a multi-year patent process, protecting a design that took years to get right, only to come full circle to a simple, elegant solution-based method and apparatus.
Long before CoreSpring®, Charlyn spent over 25 years in professional practice, including 13 years running her own Pilates studio and over a decade leading 12-week transformation programs. That structure became the blueprint for how CoreSpring® is taught today.
CoreSpring® is a patented apparatus and a complete method — built to make intelligent movement, resilience, and lasting strength accessible anywhere.
Creator of the CoreSpring® Method
Charlyn Huss d'Anconia, MA, NCPT Founder of CoreSpring LLC · Creator of the CoreSpring® Method · Co-Inventor of the Patented CoreSpring® Apparatus
Charlyn is a movement educator, Pilates Master Teacher, and the creator of the CoreSpring® Method. During nearly three decades in professional practice, she has taught people of all ages and abilities, operated her own Pilates studio for 13 years, led comprehensive transformation programs, and educated movement teachers since 1999.
Her work began with a deeply personal inquiry. Childhood back pain and adult-onset scoliosis led Charlyn to explore how movement could create not only temporary relief, but lasting change. Her education in psychology, theatre, film, Pilates, holistic health, and the relationship between the body, breath, voice, and nervous system has shaped an approach that is both analytical and profoundly experiential.
CoreSpring® brings those decades of study and practice together. Through direct spring resistance, guided presence, and intelligent movement, Charlyn helps people experience greater ease first — so posture, strength, balance, mobility, and resilience can develop from a body that feels supported rather than forced.
Her work has been featured across multiple media outlets — including podcasts and industry publications — and presented through professional fitness, Pilates, movement, performing arts and wellness organizations. See more on the Media page. Today, she continues to develop CoreSpring® Pilates and other programs for land and water, private practice, home fitness, professional education, and active aging.
At the heart of Charlyn's work is a conviction that has guided her throughout her career:
You don't need to get in shape to feel better. You need to feel better to get in shape.
