I would recommend inversion for some people. Inversion set me down a path of reversing years of compression, muscle dysfunction, and chronic pain from a tailbone injury 12 years earlier.
I also find simply hanging from a bar (or anything) gets that helpful decompression for my spine, especially if my feet drag behind me a bit. A lumbar disk will often shift back into place after hanging for a minute and maybe doing a few press ups (i.e. cobra pose with core relaxed).
