Double kong 

Also commonly referred to as a dub-kong by parkour athletes, a double kong is a variant of a specific vault known as a kong vault. A double kong takes the original premise of a long vault but allows for it to be performed over large distances. Weather it is being used over one large object or a distance between two, the double kong requires two separate hand placements at the beginning and end of the vault. Unlike a normal kong vault, you do not use the first hand placement to adjust your positioning mid-air to land back on your feet, as the first hand placement is used solely to help with vertical and horizontal travel, leaving the adjustment onto your feet to the second placement of the hands. A tip for performing this vault is that kicking your butt and legs above your head so that the push from the first hand placement does not send your feet towards the ground.

“This would be too long for a normal kong vault.”
“How about you try double kong?”
