Hi,I'm a Gokhale Method teacher who used to be a Yin Yoga teacher. I can tell you that after teaching Yin Yoga for many years, I started to have back issues. The problem being that, in yin yoga, you are encourage to bend over and hold poses for many minutes at a time. What that does is overstretching the ligaments and potentially increasing the curves in your spine. I used to see my chiro once a month for my back issues and he once told me: "I don't know what it is with you Yin Yoga people but many come here for back problems."When I told him I was going to take the Gokhale Method training he was very positive about it.Truth is, I have no more back issues and haven't seen him once in the last 3 years!
