The Ready State Virtual Mobility Coach is like having a virtual Kelly Starrett in your pocket.
I find that when my shoulders are severely lacking internal rotation my neck and head position suffer to the point where my traps actually get fatigued when running long distance even at a slow pace. Doing the sleeper stretch and some easy levator scapulae stretches seems to clear up the problem. Don’t let yourself be a victim to Delta Bravo syndrome. Remedy it before it attacks you as well!
