The course will include the psychology, philosophy and theory of yoga as well as the all-important physical aspect such as alignment in postures.
Yoga Teachers Assocation of Australia (YTAA) president Stephen Penman tells www.news.com.au: "Up to now most fitness instructors will have done a short course to teach a yoga class.
"The new standard will take a year or two to come about as instructors do the additional training."
Crucial elements of yoga such as philosophy and pranayama (breathing techniques) are more likely to be brought into fitness instructors' teaching after they have completed the course, he adds.
The news will delight those in the yoga industry who have long argued that conventional fitness instructors are ill-equipped to teach more than the very basics of yoga.
