I did this practice and enjoyed it. But, for the last week, since doing it, my right shoulder blade is killing me. Maybe held the poses too long for me?
Dearest Annie, I am so sorry to hear about your right shoulde rblade. For a test, maybe just check to see if the position of the bridge, twist or holding of the strap in the hamstring stretch cause the irritation. Usually more bend in the elbow and attention to the shoulder blade resting back and down can help, but not always. Let me know what you find out. xok
