Whip back 1/2
More like a free back handspring than a layout, the whip back is not a standalone acrobatic element in floor routines but is used in place of back handsprings to gain connection value.
That’s why the whip full is sort of a purgatory element. Rated as a C and containing a full twist, it’s starting to be difficult and complicated enough to be a standalone element. And yet whips aren’t really standalone elements; they’re the conjunctions of the gymnastics world. Hence, the whip 1/1 not really having a home. Unless you’re Lilly Lippeatt.
