As The Healing Chest Program is primarily for women recovering from surgeries related to Breast Cancer it is imperative that classes be properly planned. I review each ladies medical history each week  the few days before a class while I am planning the class for each individual group. It takes days. I also create a new "play list" of music, some type of peaceful classical; adagios, nocturnes, sometimes I use eastern style new age y, but not often. I my self am very aware of music in a class, do not like the music to be just back ground chatter. I actually kind of choreograph the class with the music. I find it helps the women feel better and enjoy the moving from pose to pose, it also helps the breathing.
