This is probably the best article that I have come across on describing the difference between should flexion and extension. As a yoga teacher, I am desperate for more articles like this. Many of my students who were office workers were just doing too much shoulder flexion and not enough shoulder extension.
I agree that there's a problem with not having the poses illustrated. Yoga Journal must have photos or drawings of the poses in their archives to post with the articles. Why not use them?
I found this article useful - the Internet is full of pictures you can find using the terms in this article. Lack of pictures is a common complaint on this website, I've found too - but I think they are trying to get us to buy their magazine ;)
This is a pretty nifty site that I often go to when I am in need of a visual example:
It's so true. This reads too technical and dry. It's just too much work to get through.
Whenever you have these fantastic articles on correct form, alignment, posture, etc. it is important for you to understand that the average person does not know how to visualize these things. Only instructors or professionals that deal with anatomy and movement planes can visualize such dialogue. The majority of your readers are not even going to bother trying to read this and make all the suggested movements. If there was a photo of someone demonstrating they could imitate the photo and then read along as they look at the image. I am seeing this more and more from yoga journal and it is becomming more and more annoying to me b/c I teach pilates and yoga and I hear the frustration from my students when they try to read these articles and just can't visualize the postitions being described. Pictures, pictures, pictures!!!!
