probably a stupid question - but was does this mean?

contra body movement position.

But good luck on getting everyone to agree on precisely what that means!

The obvious case: the creasing one hip and stepping towards your standing foot necessary for outside partner and promenade positions.

Hi Anon,
How do you crease a hip?

In the CBMP stance one of your legs will show a diagonal crease on the front from groin to hip where the thigh joints your trunk.

Here's my version of it - with a little demonstration even!!
Imagine you're in the centre of a dance floor. Face 45 degrees into the corner. Point the feet, hips, trunk - the whole schemozell into the corner.Now step across your body (with the right foot moving to the left) but the direction of the step is down the line of dance - 45 degrees to the direction in which everything is pointing.
When you're making that step, you're in CBMP. It doesn't have to be exactly 45 degrees of course.
I hope i'm right on this - please let me know if this isn't correct (don't all shout at once please!)

Hi Phil,
I understand that. Stepping down the LOD will certainly crease my hip! More important, probably, is that Blackpool starts today. I will be going next week.

Dancefad. In the Waltz try 456 of a Reverse Weave. On the first step if both you and your partner are not in CBMP with the lady stepping outside body facing wall, yours the center. It should be long and cigar shaped not wide and short. That is one use of CBMP.

Seems to be the outside change action. Lady goes outside partner on the first step.

She needs to send her body over her foot, putting the foot through first puts the thigh through and forces the bodies apart to "four hips wide". Putting the body through with both partners in good CBMP shape lets the bodies stay in near contact with the thighs not interfering.

The Man needs to be sure not to begin his turn to the left until the second step - check the book, there is no turn on the first step. In fact, the figure will work better if he winds up his body (but not his feet) slightly to the right while leading the lady's outside partner shape. But most ruin the step by turning to the left too early.

Dear Anon,
CBMP meas place the stepping food in one tract or accross the standing foot without body turn .
When we perform CBM , our body should turn toward the stepping foot ( foreward/ backward ).Are our feet should also be placed in one tract? I think so. doesn't it ?
