Whilst walking, one swings the arms in an
aggressive & sometimes uncontrollable manner perpendicular to the body, in an attempt to gather momentum & propel the body forward thus compensating for an inability to move efficiently.

This characteristic is often exhibited by more rotund individuals, to overcome the high level of inertia whilst initiating movement.
