A wise Pilates/Feldenkrais teacher introduced me to this book. Using "Somatics" I personally found relief from chronic lower lumbar pain, and got help retraining my gait and balance after a severe ankle injury.The book is simple to understand with sections for various problems.
Somatics are a system of gentle movements - while breathing and mildly focusing (and sometimes simple "looking" in certain directions)- which through a combination of neuromuscular stimulation and the gentlest of stretches (no pain!) manages to to roll back years of stiffness, aid injury recovery, and significantly relieve some of the stresses of aging.
Somatics is based on sound science, and Feldenkrais, yoga, and Pilates are related. But Somatics exercises - movements really - are even gentler, and smarter, No equipment but a towel or mat is needed. Any level of fitness can benefit, even someone in a wheelchair or bedridden can do some of the movements.
If you have the patience and interest, I suggest reading the book and working through every single exercise presented, which is what I did coming back from traumatic injury. Some will "speak to you", and you'll incorporate them later into daily practice.
If you lack the patience or the time for this, the book is still valuable for its simple "CAT STRETCH" a five minute series of gentle movements which gently moves the whole body and seem to me like "the fountain of youth" . I do the cat stretch twice a day - on arising and before bed.
I could not recommend this book and Somatics in general more highly. Your back, ankles, knees, hips, shoulders, and neck will thank you!!!! And so will your friends when you pass this book along!
