Thoracic mobility is one of the most important mobility drills for the fitness athlete. The thoracic spine plays a huge role in keeping the shoulders and the lumbar spine working properly, and pain free. To test thoracic mobility, I look at rotation each direction. This lets me know if there is a unilateral restriction. Limited rotation also means there will be decreased extension in the thoracic spine.
