Quite a few things! “Yoga is a complex system of health with origins that date back more than 5000 years,” Hester Campbell, aerial master trainer and Pilates instructor at Gymbox, explains. “Aerial Yoga uses asana (pose) and pranayama (breathwork with the aerial hammock). Aerial Pilates, by contrast, uses the classical principles of Joseph Pilates, which are the following: Alignment, Balance, Breathing, Control, Concentration, Centering and Flow," Campbell adds. “The main difference is that yoga has an aspect of spiritual experience moving towards enlightenment and originates from the East," the expert explains. "Pilates was German and his approach to health was very much a Western European one — he studied every form of movement he could find (including yoga) and with his knowledge of gymnastics, bodybuilding and naturopathic medicine and strived to help all people become stronger and healthier versions of themselves.”
