Head - pretty straight forward with slight up and down brought on by the shoulders
Chest - hunched with a bit of give to allow for heavy breathing
Hips - slight thrust and rotate focused forward to balance out the curvature of the chest
Arms - never really straighten out always bent on the forearm don't overlap backward too much to keep focus on the forward movement
Hands - tight fists with a little give throughout to allow for non rigidity overlap and drag on the wrists.
Feet - a bit of pound on the steps by adding a bit of backwards rotate and large spacing between the frame before the step and the step
