Movement: Stand facing close to a wall and gently extend the arm towards it. Finding a spot that provides a gentle to moderate stretch, place the palm against the wall and very slowly and gently rotate the chest until the arm is parallel to the wall or the stretch is no longer comfortable. The hand may be placed higher or lower to shift the emphasis of the stretch.
Repetitions: Hold for the full prescribed time on one side, then switch sides and repeat. This counts as one set.
