The diagram below illustrates the sequence of instructional progressions for learning a "head-lock / squat / whizzer throw" maneuver. Picture 1 shows the terminal position that should be attained if the skill is executed correctly. In accordance with correct pedagogical principles, each trial must be completed successfully by attaining the desired terminal position. This sequence requires the first step prior to the terminal position to be executed in the air. Consequently, an opponent has to accommodate the attacker so that this step can be performed correctly.
