Just weighing in after a couple of months away from the Connect….I agree that Legs up the Wall is a wonderful exercise for calming the mind and re energizing the body through recirculating blood. However, because it is an inversion posture, it is not good to do if you have sinus infections or brain or eye bleeding. If anyone wants a short tutorial about getting into and out of Legs up the Wall let me know or just pull it up on U Tube.
Also I really relate to the sudden cervical condition mentioned earlier by wgatap21 with necking cracking and (for me) arthritis in C 6/7, which has caused tremendous pain. I'm actually having a cortisone shot in my neck this Friday for pain relief as I found injections in my lumbar spine to bring significant relief. ha ha John about the snap, crackle and pop… which I too understand is more annoying than it is any medical concern.
