Acroyoga (also written Acro-Yoga or AcroYoga) is a physical practice which combines yoga and acrobatics. There are now many schools of AcroYoga. The original two schools were Acroyoga Montreal and Acroyoga Inc.. Acroyoga Montreal was founded by Jessie Goldberg and Eugene Poku in 1999 combining acrobatics, yoga and dance. Acroyoga Inc., began in San Francisco in 2006, founded by Jason Nemer and Jenny Klein. This practice blends acrobatics, yoga and healing arts. Both schools offer teaching certifications, and despite some differences have many similar poses while using gravity to promote strengthening and stretching.
