Dear Anonymous, Thanks for clarify when the core muscles use in forward walk. I have some question to make clear, please give more teaching tips. Thanks.
I understand moving leg only bears itself gravity. standing food supprot rhe remained major body wiehgt , the hard time is at the moment of half stride. moving heel even off floor transiently while half BD weight is approaching the new standing leg. When flexing the old standing knee, BD should vertically on the supporting point or BT , hip gravity behind the ball and flexing knee but not beyond the heel, moving sliding back to the position without hip tilted , center weight continuously drives away through the heel toward the new standing foot , the stride increasing as a result...
What do you mean about " allowing her hip to lag a slight distance behind her knee '? I thought hip to lag a slight distance behind heel " will make problem because of wrong distribution of body weight to standing foot and floor which affects the generation of kenetic energy and obtain effective stride. Correct me if I am wrong. Thanks.

Dear Anonymous,
I thought , although the standing heel is beneath the hip and spine, but the center weight should be toward the flexing standing knee and standing spot. and partner through the standing thigh. that meants knee and foot are supporting body weight , due to flexing knee and ankle speedly, we got kenetic energy to drive center weight away continuously... due to flexing knee, moving leg sliding back to its limit depending on where the body weight distribution, how much knee flexing , assistance of muscular contraction if needed. Correct me , if I am still wrong.

This is the longest thread ever done on this site. I don't even bother to read most of it. I have no clue who is contributing and their qualifications on what they are writing. There must be some way to attach the manual description with comments. One of the worst things a dancer can experience is wrong or bad information. Once you include it into your muscle memory it is not easy to erase bad information or movements.

Or qualify your self by referring to your previous published dance writings so we would know that you are for real.

I understood and experience how wrong or incompleted information wasted money and time, how hard to erase incorrect muscular memory.
Here is a website for asking and discussing questions and sharing experience or knowledge, althoug its contributing is not as much as dancing college, Alex Moor,Marcus, Luca, it is part of strong fundamental stones where evolution and champion generated. I believed there must be a person who can teach me belong the three persons walking .¤T¤H¦æ, ¥²¦³§Ú®v. I even no care of a dancer or a therapist he/ she is . Relative correct data must be sensible and practicable . It should be completed gradually through upgrate. We absorb other thought or view to get advance. I even don't care of consult a dacner, or a therapist or a student who did good on one step. I much more care of the concept itself , not only the qualification .

"First that's an odd definition of balance. But second there is not distribution between moving feet - the weight is entirely on one foot or the other. Plus it's pretty hard to have moving feet (plural) unless you are a quadraped"

If the supporting heel is leaving the floor AST as the other is moving forward then both feet are moving!

"If the supporting heel is leaving the floor AST as the other is moving forward then both feet are moving!"

You will confuse many with that definition of moving, as the foot has not left it's place on the floor.

It also doesn't happen anyway. The standing heel will not lift until just before the moving foot passes it (for an upswing step) or just before the moving foot is placed (for a flat step). Both of these are long after "AST as the other is moving forward"

'The standing heel will not lift until just before the moving foot passes it'

Well, both feet will be moving. I find it strange that you could interpretate the defination by Anon that both feet would be moving forward at the same time.

"Well, both feet will be moving. I find it strange that you could interpretate the defination by Anon that both feet would be moving forward at the same time."

During the time in which the standing foot is flat on the floor, it is not moving - it's muscles may be changing position, but the foot itself is stationary with both ball and heel in contact with fixed spots on the floor.

Anon apparently considers that the standing foot is moving once it starts to roll forward, which is picky but true. However he or she was mistaken in thinking that the rolling began as soon as the free foot started moving. For a flat step the standing foot does not roll during most most of the stride (standing heel starts lifting only just before the moving foot finds its new place), while for an upswing step it starts slightly less than halfway through the stride (standing heel starts lifting just before the free foot passes it)

I didn't mean that at all. At the commencement of a forward walk the body weight will be held in the ball of the supporting foot with the heel lightly touching the floor. Once the body weight moves out of the foot the heel of the supporting foot will be raised and that will occur before the moving foot reaches its destination and the body weight transferred to become the new supporting foot. Hence between moving feet.

"Once the body weight moves out of the foot the heel of the supporting foot will be raised and that will occur before the moving foot reaches its destination and the body weight transferred to become the new supporting foot. Hence between moving feet."

The body weight can move, for all practical purposes the entire floor pressure used has to be in the standing foot until the moving foot has found it's position - moving an even partially weighted foot is extremely bad technique.
