I have Disc Degenerative Disease, a bulging disc in my lower back ( L4, L5), and abdominal muscles that split during pregnany. I am a very petite 36-year-old woman 5 3 and 101 pounds. After working out my abs, my back always suffers, ever since they split. I ve tried physical therapy and a chiropractor to no avail. Cortisone shots do help, but I don t want to do too many of them. What do you suggest?
