Where do you yoga teachers go online? What are the best forums & sites in your opinion for developing your practice and teaching?
For starters, here! I am a teacher and have often called upon members for assistance. They have given me much insight.
Another site that is good is yogajournal.com They have a wealth of info from teaching methodology to anatomy.
aypsite.org outlines the 8 limbs very well, his 8 limbs of yoga is one of the best and easiest to understand in my opinion
