I realize there are other threads about this but I was hoping one of the many instructors we have here could answer a few questions for me. I have a young friend who is still growing and I would say has a mild case of scoliosis. I assume Yoga could be beneficial to her physical state but I only practice myself, I have no training in the teaching area, what can I tell her about how a regular stretching program would do for her? Can Yoga actually straighten your spine or just strengthen the surrounding muscles?
