The dos Santos
With one gravity-defying combination at last year's worlds, Brazilian gymnastics dynamo Daiane dos Santos raised the standard for floor routines. The 21-year-old performed a half twist into a front-facing double flip (or double Arabian) at the tail end of a tumbling pass; the move (left) was unprecedented in that it was done with the legs straight and tight to the body. Since dubbed the dos Santos, the move will be performed in Athens by its eponym and possibly a few other bold souls—the U.S.'s Courtney Kupets included.
