01 / BASE
The action begins with support.
The supporting side accepts load and presses into the ground. The ground exerts a reaction force; foot, leg, pelvis, and trunk coordinate that interaction with the intended action.
Base → pelvis and trunk → Anchor
Identify the loaded support—not merely the foot furthest back. Trace how the support contributes to the executing side.
