Dear Don, last night in the studio,
I was advised to fold up my inguinal line of standing side deeply for progressive movement . The coach ( not mine ) showed me how to do that , but I noted she sat down with heavy hip then " Up" ( not gradually rising throughout the steps in natural turn 1-3 in waltz ) with markedly receiving foot rejection. She did not use the pendulum action to swing her moving foot into the position but push from her standing foot including hip.( broken hip line occurred . )

I prefer to transfer my body weight with the power of standing foot and knee ( rotation and press the floor ) together with the pulling power from swinging action of moving leg.

In the teaching video clip, Karen mentioned about the big X across her fronts and upper lateral thighs to avoid the big fold.
( shoulder ,ribcage , hip, ball in one line vertically )

I said : "I need to consult other experts to see if this is a new development as you said. Yes, I noted some dancers practiced such kinds of exercise . But I did not see them use it in their dancing .
Generally. the technique developed is better . but you knew, it is not easy to learn exactly. Correct information is vital.

In my opinion , body moves in constant speed generally, it arrived its midway extremely close the maximum stride , sitting up hip position should be cared. I flex my moving ankle hard with soft knee ( maybe not soft enough in my current level )to catch my body weing on the receiving ball, slow down the heel lower. keeping my wight toward partner, I just let them naturally happen. Whether I was wrong or right , I will let you know. Thanks ."
My question is how to let our pelvis in its middle level with minimum use of muscle tone ?
I tested it by standing with heels closed, toes turn out as much as I could, without extra control I squated down with heels touching floor. Is that the muscle tone I need ?
Thank you.

The important pendulum action is a motion of the body. The leg may swing in a somewhat similar path from its suspension at the hip, but that's not really part of the pendulum motion, it's just something that also happens.

You do not ever want to be pulled by the weight of your moving foot, as that would mean that your leg swing had preceded your body swing, which is backwards. Body swing starts before leg swing, thjen leg swing overtakes the body swing just an instant befor the body arrives, but not early enough or far enough that the foot can in any way be said to pull the body.

It seems like this other teacher may have some good points. Try to really study what they are doing in addition to their words.

Thank you so much to correct me.
You detailed what the pendulum action is and how to do it .
With one side swing up, the effect is better.
I talked to other coach who takes regular lesson with some Italian competitors last night. She suggested me to press my abdomen toward my spine as much as more and focus to centre drive. We repeated" walk", "five step" for what she meant. She also taught me how to use the back muscle ( both sides )to increase the side way speed. It was instructive also.
Thanks all of you.

Yichen. I think what also needs to be looked at is. For the lady 123 Natural Turn Waltz. The leg stays under the hip in relation to the body on step two. On step two the body will be on an incline. But if you were to stand up at this point your right leg will under your own hip line. Swing and Sway is also a part of this. I don't understand the broken hip line unless the teacher is crunching there side which is wrong.
Best wishes.

Not sure if this is what was meant, but any step with full CBM, as well as any step into CBMP, will show a marked crease where the pelvis and moving leg (forwards) or standing leg (backwards) fold together.

Some people leave this creased hip line out of the CBM actions, but that causes numerous hold and coordination problems since the hip and thigh that should be back are then left projecting against the partner.

Try to really study what they are doing + their words.
Yes, I should calm myself down first ,even it looked sitting down. marked bouncing on 1. not smooth from 1 to 2. then realy study what it was.
I learnt from you not only dancing. Great thanks.
Another question about " slow". In slow foxtrot (and tango), someone said the first step arrives at 2. I asked him what you did before 2 ? It looked like q. He answered: "we were taught on this way." Is it a trend ?
