Shoulders
Introduction: Shoulders control your upper torso. Do it right.
Compare: All in sync except for Pose Running which did not mention shoulders.
Do: Relax shoulders.
Don't: Excessively rotate/twist shoulders. Hold your shoulders high/tight.
Why: What happens with your upper torso drives your lower torso's movement.
How 1: Drop and relax shoulders.
How 2: Slightly nudge your shoulder blades back and together.
Imperfect Practice: Drop & relax shoulders then raise them up and tighten them. Nudge shoulder blades back then forward. Minimally twist shoulders forward and back, then rotate a lot, then freeze with no rotation.
Feel: Should feel less stress and free flowing movement with minimal muscle tightness/energy.
Story: After 22 hours of running I stopped and laid down. I screamed in pain….not pain in my legs, but from my shoulders. They were as tight as an ice rock from 22 hours of holding stress by holding my shoulders high.
