Tumbling: Any hip-over-head skill that is not supported by a base that begins and ends on the performing surface.
When no tumbling is allowed after a particular tumbling skill, at least one step into the next tumbling skill must be included to separate the two passes. Stepping out of a skill is considered a continuation of the same tumbling pass and an additional step is needed to separate the passes. If the athlete finishes the skill with both feet together, only one step is needed to create a new tumbling pass.
