This is an improvisation on Yoga Synergy’s Nerve Tensioning Exercise. Nerve Tensioning is a set of five positions that aims to tension the brachial nervous plexus. These positions are primarily done by internally or externally rotating the shoulders and wrists. Since shoulder movement creates associate movement in the spine, it is possible to “reverse the engineering” as Simon Borg-Olivier calls it and initiate the movement from the core thus appear in a series of forward and backward bendings, the shoulder and arm movement, in turn, becomes “associated”. The original five positions become less visible and are replaced by a figure “8” described by the arms.
