Many low back exercise programs through the continuum from rehabilitation to performance are based on the philosophy to enhance the range of motion and build strength. Yet performance often depends more on short range stiffness, rate of muscle activation/deactivation, and technique to minimize "energy leaks", and optimally "steer" strength. At the rehabilitation end of the spectrum, many of these programs fail - either more patients are created, or are exacerbated. Often the causes of the back troubles are replicated in the exercises! Unfortunately, while many exercises are promoted as stabilization exercises, and specific muscles are claimed to be the most important stabilizers - in fact these claims have been made without the quantification of stability. What is myth, and what is factual? While my textbook elucidates the mechanisms, buttressed with references and data, a few brief thoughts are provided here.
