The GYROTONIC® and GYROKINESIS® Methods are complementary exercise methods that fall under one umbrella- the GYROTONIC EXPANSION SYSTEM®. Both methods were developed by Juliu Horvath, an ethnic Hungarian, professional dancer from Romania. Horvath suffered a series of debilitating injuries during his dance career, and began developing what are now known as the GYROTONIC® and GYROKINESIS® Methods as a way to heal himself and regain his strength and agility.
