Today’s mission is to improve the most significant shoulder range of motion for the athlete, internal rotation. If an athlete is missing IR, then the shoulder HAS to compensate by translating forward. This loss of positioning affects mechanical advantage, the ideal length-tension relationship of the joint’s contractile features, joint congruency, and stability. In my clinical practice, treating this tacked down shoulder tissues is one of the first things I check when an athlete is missing this range.
Mission: 4-5 minutes a side for the IR mob, then 2 min/side for the big ole Hand behind back pec mob.
Test/Retest: Snatch Pull, Dip
Leopard Bonus: What movements do you see affected by lack of shoulder IR?
