I went to physical therapy for two months because that’s all insurance would pay for. My spine was weak and lacked stability. They had me doing stretches for back mobility and core strengthening. I continued that when insurance ran out and added in a lot of walking and other light weights and calisthenics.
It’s been a long journey and I’m only half way to where I was. The worst part is I did it to myself by becoming sedentary for to many years.
