I have advanced low back vertebral issues and am working with a McGill personal trainer. There are a couple of exercises that are no- nos. They are knees to chest exercises and spinal twists. I can attest to the pain that occurs when I twist my spine. The knees to chest excercise gives temporary relief.

Apart from taking medication, ( acetaminophen), learning how to align my spine in every day functions such as sitting, standing, squatting vacuuming, washing etc. is very helpful. Changing old everyday habits of movement functioning has been a challenge but worth it.

Hope this helps.
