Gyrotonic was introduced in Europe in 2001 and has slowly gained popularity, here in Manhattan. Derived from the words 'gyro' (spiral) and 'tonic' (tone), Gyrotonic promises to enhance range of motion, balance and coordination, to stretch and strengthen muscles and tendons, and to articulate and mobilize joints. At Body Evolutions, Billy Macagnone was trained by the originator of this body building idea and has the largest facility in the city dedicated to this form of exercise. Both he and his trained staff are available to work one on one with their clients or they offer a variety of classes.
