Shoulder gets pulled taut into protraction when you let it dangle and swing centrifugally:

im allways cautious for injury and having a muscle at its limits and then applying force to it is not a sustainable solution for me. i assume you mean the shoulder should be protracted when you start accelerating? im well aware that the upper arm should never move far away from 90 degrees of your shoulders. aka hugging yourself or ''strong arming''
