I prefer hiking to any other form of exercise but I have PT exercises I do to help with my pain-being outdoors works for me on so many levels. I also have a gazelle that I run on at times which is good because it's not weight bearing & I blast music via the ipod. It gets me out of my head which helps my OCD & racing thoughts, decreases my depression & anxiety & overall I just feel happy when I do it. I also do a lot artwork while listening to music which also gives me some of the same positive effects. Thanks for this thread.
