What does "FX back 2 1/2" refer to in a gymnastics routine?

The term "FX back 2 1/2" specifically refers to a backward flip that includes two and a half rotations during the execution of the skill. In gymnastics, the notation captures both the direction of the flip (backward) and the number of rotations completed in the air, which in this case is two and a half.

This terminology is crucial for judges as it allows them to clearly discern the complexity and difficulty of the movement being performed. A skill of this nature demonstrates advanced technique and control, which are essential elements in scoring at higher levels. The recognition that this move involves a backward rotation rather than a forward one is vital for understanding the skill classification and its execution in the routine.
