Analyzing the Gyrotonic® arch and curl

SummaryThis article examines a foundational movement in the Gyrotonic Expansion System® known as arch and curl. The Gyrotonic Expansion System, created by Juliu Horvath beginning in the 1980s, is a relatively new approach to movement based on three-dimensional spiraling and circular patterns, with applications in exercise, therapy and rehabilitation. Beginning with an overview of the Gyrotonic Expansion System, this article will explore the basic principles of Gyrotonic movement, and define key concepts, before looking at the specific biomechanics of arch and curl. We highlight common problems clients encounter with arch and curl, and consider applications to movement and bodywork.
