I hate to sound like a yoga zealot, but it has helped me a great deal with relaxation and eliminating aches and pains. I have some arthritic knee issues and my strength and mobility has improved so much. All of the instructors I have met encourage going at your own pace. In addition, there are all kinds of classes. I attended a restorative yoga class last Monday that involved all gentle poses in prone positions with breathing emphasized. All classes end with a meditation period. I know it can be intimidating for some, but it is okay to go at your own pace. It took me six months to build enough strength to even try certain exercises, but my body can do things now I never imagined. Or could pre-transplant. Movement of any kind is powerful medicine.
