An "FX back 2 1/2" is classified as which type of skill in gymnastics?

An "FX back 2 1/2" refers to a specific skill performed on the floor exercise where a gymnast performs a back somersault with two and a half rotations before landing. This skill is classified as a difficulty skill because it involves a complex movement that requires a high level of technical execution and body control. Difficulty skills are those that challenge the gymnast's abilities and contribute to the overall score based on the level of difficulty executed in a routine. The inclusion of such skills in a routine is essential for achieving higher overall difficulty scores, which can significantly impact the final score in a competition.
