Which locomotor skill requires a foot to finish two tasks before weight is shifted to the other foot?

The skill that involves finishing two tasks with one foot before transferring weight to the other foot is skipping. This locomotor skill is characterized by a two-part movement that involves a step and a hop. When a child skips, they alternate pushing off with one foot, landing on the same foot briefly, and then transitioning to the other foot after completing the step-hop sequence. This rhythmic and coordinated action clearly distinguishes skipping from other locomotor skills that do not share this dual movement with a single foot before weight transfer.

In contrast, walking and running involve different patterns where weight is shifted more fluidly between feet without that distinct step and hop sequence. Lunging generally involves a forward movement where one leg supports the body while the other leg is extended, but it does not require the specific dual task completion associated with skipping. Thus, skipping is the locomotor skill that fulfills the criteria outlined in the question.
