Battement, sinking down, developed. This is an exercise in which the supporting leg is slowly bent in fondu with the working foot pointing on the ankle. As the supporting leg is straightened, the working leg unfolds and is extended to point on the floor or in the air. The movement is done devant, derrière and à la seconde. In fondu forward, the conditional position sur le cou-de-pied devant is used. In fondu back, the basic position sur le cou-de-pied derrière is used.
