The letter Y. As long as you’re illiterate.
The Y turn on beam remains surprisingly popular despite its increased risk compared to the equally valued L turn. Theoretically, the leg is supposed to be held in a split throughout, but more often you’ll see gymnasts touch their leg in split position for exactly one millisecond of the turn and do something halfway between an L and a Y for the rest of it going, “I do Y spin!”
