For arthritis and other problems with the lower back - scoliosis, stenosis, listhesis, disc degeneration, the presence of arthritic spurs - A strong set of core muscles helps immensely. I'm 70 y/o and my spine surgeon told me that my stone core was literally holding my lumbar spine together. (And I have each of the conditions listed above.)

If you're interested in this, check with your Dr first and see if there is a PT he can recommend, so your insurance might cover it. It may take time, but it beats having to take pain medication.

All the best to you.
