Each day of my rehabilitation, I gained confidence and ability. Having lost all strength in my stomach muscles, I found it nearly impossible to maintain my balance
if I leaned to one side or the other. Sitting on a mat with my legs straight in front of me, I would attempt to raise my hands, first one inch, then two.
Raising one arm ever so slightly was enough to topple me sideways. I hadn’t the strength to sit back up again on my own. I soon realized that my center was my trunk,
my chest. If I maintained balance there, I could incrementally work at raising my arms. Soon, understanding this concept, I could raise both arms shoulder level.
