Gyrotonic methodology is an exercise system to increase the functional capacity of the human body. The Gyrotonic Expansion System® was specially conceived regarding key Gyrotonic principles, swimming, ballet & yoga through which major muscle groups are worked independently & in an integrated manner. Unlike most conventional exercise systems where linear or isolated movement patterns are performed, the Gyrotonic Expansion System emphasizes multiple joint articulations through full range of motion which a healthy body naturally explores. Through uniform and permanent resistance it allows both non-athletes and athletes to strengthen their body through all changes of direction as well as within the pivot axis. Special attention is paid to increase the functional capacity of the spine, resulting in a superior and well proportioned body, which is significantly less prone to injuries. The concentric and eccentric forces executed by the involved muscle groups are maximized and evenly distributed between the agonist & antagonists muscle groups creating a strong, stable and well balanced body.
