Quick answer: an extension is a stunt position in which the flyer is held above the bases' fully extended arms, standing with both feet supported. It's a step up from a prep in height and difficulty.
What Does It Look Like?
In an extension, the bases' arms are straight overhead, holding the flyer's feet, with the flyer standing tall and balanced well above head height. It requires more strength and stability from the bases than a prep, and more core control from the flyer.
Who Is Involved?
An extension is built by a full stunt group - a flyer, two bases and a back spot, with a front spot sometimes added for bigger or higher-difficulty extensions.
Where It Fits in a Routine
Extensions are used both as a stand-alone stunt and as the base position for higher-difficulty skills - many single-leg positions and toss skills load through an extension before transitioning further.
How the Term Is Used
"Extension" describes both the two-leg position itself and, more loosely, the general height category - as in a "single-leg extension" or "extension prep," referring to a single-leg stunt held at extension height.
Related Skills
The extension builds directly on the prep, and is often a launching point for single-leg positions like the liberty, or for toss skills.
Level / Division Context
Under the USASF All Star rules (2026–27), two-leg extended stunts are allowed from Level 2. At Level 1, a stunt may only pass immediately through an extended position - it can't be held there. Extended single-leg stunts, such as an extended liberty, are allowed from Level 3.
What Judges Look For Conceptually
Judges are generally looking for full arm extension from both bases at a matching height, a stable and centred flyer position, and clean, controlled timing on the load and dismount.
| Prep | Extension | |
|---|---|---|
| Flyer height | Shoulder level | Above the bases' heads, arms extended |
| Base arm position | Bent, at shoulder height | Fully extended overhead |
| Typical use | Entry-level stunt, transition point | Higher stunt, often a base for further positions |
