As discussed in Make Shoulder External Rotation Stability Exercise A Full Body Movement video and blog post, the fascia connects the hips to the shoulders and affects movements involving those structures.
The study of human movement teaches us the opposite shoulder internal rotation is enhanced when the opposite hip complex has ample internal rotation motion. Likewise, the same side shoulder internal rotation is enhanced when there is ample external rotation of the same side hip. It is important not to confuse these concepts with the previous blog post exploring integrated shoulder external rotation.
Through the understanding of the Posterior X-Factor Flexibility Highway, the tissues connect from the opposite calf group into the hamstrings, connects to the ischial tuberosity, via the sacrotuberous ligament to the lumbar fascia, to the opposite latissimus dorsi, to the opposite shoulder. This relationship is conducive for rotation and flexion movements to the opposite side.
Shoulder internal rotation exercises typically have been done using a band, tubing, or some form of cable system. These are effective movements, however, are isolated to the shoulder joint and tissues around the joint.
In addition to the traditional movement pattern of band or cable resisted external rotation exercises, we integrate the Posterior X-Factor into the movement pattern. By doing so, the opposing hip gains range of motion through internal rotation, the abdominal complex is loaded, and the anterior musculature of the shoulder girdle (obliques, pectorals, anterior deltoid) are strengthened. Additionally, the same side hip can gain greater range of motion into external hip rotation. The benefit is this exercise becomes a full body movement rather than only isolated.
