Hi Diane. CBMP. Means. Contre Body Movement Position.It is the position attained when either foot is placed across the front or the back of the body without the body turning. Even the novice should remember that every step taken outside the partner, or with the partner outside must be placed across the body in CBMP to ensure that the two bodies are kept in close contact. So if you put your left shoulder forward over your left foot, without turning place your right leg forward across your body. This would be the fourth step of a Reverse Weave in the Waltz International Style. Your partner will be moving backwards down LOD you going forward down LOD. LOD being the Line of Dance. CBM. is the action of turning the opposite hip and shoulder towards the direction of the moving leg, and is used to commence all turning movements. A Backward Turn to the Right. Step back with the LEFT FOOT and at the same time swing the right hip and shoulder backwards. An important point to remember is that CBM does not alter the direction of the step.This should be an action without strain or stress so don't over do it. Happy Dancing.
