Ok, in an attempt to focus more on the scap I made the question more generic (instead of rear hip/both hips..etc.).
What causes the scap pinch ?
A) The scap muscles contract and pull back and create the rear scap pinch "manually".
B) The loading of the core flows up the body and creates the rear scap pinch "dynamically".
C) The loading and unloading of the core flows up the body and creates the rear scap pinch "dynamically".
D) Both A & B combined.
E) Both A & C combined.
F) Other
Please let me know your thoughts.
