If you stretch twist and crack your back I have one message for you: pack it in!!
“Soft tissue injuries result from excessive tension, so excessive tension in the rehabilitation situation is counterproductive…stretching of …chronically tight tissue is counterproductive. It may give an initial sensation of relief because the muscle spindles have been deadened, but this practice…weakens the tissue further because of the weakened proprioceptive response.”

“stop trying to Stretch and mobilise! Let tissues settle and regain their proprioceptive abilities so they tell the truth”
