Double-Double

A double-double is a high-difficulty tumbling pass consisting of two complete backward saltos (flips) combined with two full twists, all performed within a single aerial element. It is most commonly executed on the floor exercise as a backward tumbling pass.

Simone Biles is among the most notable gymnasts to perform double-double variations, including both the double-double tuck and the double-double layout on floor exercise. The skill has become increasingly common at the elite international level as the overall difficulty of women's and men's gymnastics has risen.

The double-double is most commonly performed on floor exercise, but in men's gymnastics it also appears as a dismount from the high bar and as a release move on that apparatus. It is virtually never attempted on balance beam due to the extreme difficulty and narrow landing surface.

In a double-double tuck, the gymnast pulls their knees toward their chest during the saltos, while in a double-double layout, the body remains extended in a straight position throughout. The layout version is significantly more difficult because the extended body position slows rotation, requiring more height and power to complete the skill.
