The Gyrotonic Expansion System is composed of the Gyrokinesis and Gyrotonic exercise methods. The Gyrokinesis Method, originally called “Yoga for Dancers,” is practiced on a mat & chair, and the Gyrotonic Method uses specialized equipment that permits one to move with support and resistance. Gyrotonic and Gyrokinesis exercise sequences are intended to increase the functional capacity of the entire organism in a harmonious way. Both methods embrace key principles also found in swimming, dance, yoga, tai chi, and gymnastics, and emphasize continuous, flowing movements, synchronized with corresponding breath patterns.
Gyrotonic and Gyrokinesis exercise sequences are usually taught in a one-hour private or group class at a Gyrotonic studio, or fitness facility.
