In gymnastics, what does "FX full in back out" mean?

The term "FX full in back out" in gymnastics refers to a specific type of tumbling pass often performed on the floor exercise. The phrase indicates a sequence where the gymnast performs a double flip while achieving a full twist inward during the initial rotation and then transitions into a backward rotation for the landing.

The "full in" portion means that the gymnast executes a full twist as they complete their forward flip. The "back out" aspect indicates that the final segment before landing consists of a backward rotation, which is a crucial characteristic of the skill. This combination showcases advanced skills and difficulty, which are essential components of scoring in competitive gymnastics.

Understanding this terminology helps in recognizing the level of difficulty and execution required for elite-level routines, particularly for floor exercise skills.
