Extended Stunt: When the entire body of the top person is above the head of the base(s). If the primary base(s) squat, go to their knees or drop the overall height of the stunts while extending their arms (excluding floor stunts), the skill would be considered extended. Stunts where the base(s) arms are extended overhead but are NOT considered “Extended Stunts” since the height of the body of the top person is similar to a prep level stunt are: chairs, torches, flat backs, straddle lifts, suspended rolls and leap frogs.
