Uniform Muscular Development

Use your WHOLE BODY with every exercise. Pilates does not break down movement into separate pieces (legs one day, arms the next). Each exercise engages each muscle group appropriately for unified development of all muscle groups. For example, when the legs are in motion the arms may be working to stabilize the movement. When the arms are in motion the legs may working to stabilize and support that movement. Other systems in the body are also being uniformly developed from the Circulatory System to the Respiratory System to the Digestive System.  

Patanjali

lit. "possessed of reverence." A Saivite Natha siddha who lived sometime between about 200 B.C.E. and 200 C.E., but the exact date is unknown. Patanjali traveled throughout much of India, studying and analyzing what different practitioners and teachers were doing under the name of "yoga" and then codified the ancient yoga philosophy that outlines the path to enlightenment through purification, control, and transcendence of the mind.
