In an ideal world, the idea of practicing Yoga solicits feelings of calm equipoise, energy and vibrant health. However, for many people the idea of practicing Yoga in the context of a structured class can bring up feelings of apprehension and fear. There may be any number of reasons for this apprehension. Some of these reasons include being physically or emotionally fragile. This sense of being physically fragile can come from being injured or in the process of healing from a surgical procedure.
