Cross Body Lead (CBL) is a common and useful move in Latin dances such as Salsa, Mambo, Rumba and Cha-cha-cha. Basically, the man on counts 2 and 3 of his basic step (assuming dancing on 1) does a quarter-left turn (90° counterclockwise) while still holding on to the woman. On counts 4 and 5, he leads the woman forward across him, i.e., firmly leads her with his right hand on her back, so that she travels across and turns around and faces the opposite direction she was facing. At the same time, the man does another quarter-left turn as necessary in order to follow the woman and face her. At the end of the move, the dancers have their positions exchanged. The cross body lead can be done with single-hand or double hand hold, with or without a woman's underarm turn, or leading the woman to do a free spin.
