Round-off 1/2 on, lay
Yurchenko half on, front layout
This is perhaps the rarest of all the round-off 1/2 on vaults, and I’m totally fine with that. On front layout vaults with no twisting, it is borderline impossible to maintain a body position that doesn’t look like a rogue banana hurtling through the air. Obviously one of the reasons this kind of vault is increasingly unpopular. The Banana Principle.
For those progressing through the round-off 1/2 on vaults, we pretty much always see the pike 1/2 become the layout 1/2, rather than the layout become the layout 1/2.
