Other Names: Piked Double
This trick is a Double Somersault, but executed in a Pike position, rather than a Tuck.
Start the trick like a Layout. Set at the platform and break hard at the poles. As you let go of the bar, make a pike position with your body as you make a double back somersault and open for the catch.
Other double somersaults listed on the site (with twists etc.) can also be executed in a Pike position.
