I read with great interest and sometimes it raises a smile
All those who believe the body is ahead of the foot are not thinking correctly. The spine is the centre of our balance. we drive the spine forward. Call it what you like. Bodyflight will do. We flight the spine but the foot will always beat the body. We have within us an in built instinct to do this otherwise when we dropped out of the trees a million years ago we would have fallen face down the first time we tried to walk. Personaly i dont believe that those who THINK there body is ahead of their feet have ever watched themselves on a video.

"We flight the spine but the foot will always beat the body."

The foot will beat the body to the FINISH LINE,

but the body will beat the foot OUT OF THE STARTING BLOCK.

From a standing still position. When I move my body from over my heel to the ball of the foot. Not the toe. Is my body in front of my foot.
To make the point try this. Stand with the feet together. With your feet together make sure all of your weight is on the RF. You could lift your LF. Now put all of your body weight onto the other foot. Has my body gone beyond my foot. That is of course a sideway movement. But if I did step to the side what will move first. It wont be my body.
So now we spread our legs front to back at full stride. Front leg and back leg straight. Send your weight from the cental position over the heel of the front foot onto the ball. This is where the leg will take over. It will move ahead of the body.This is a perfectly natural muscle memory thing that none of us have to think about. What we dont want is somebody thrusting there leg out too early and so far ahead they have to play catch up.
Body in front of your moving foot. Give us a break. I would feel like a cyclist running in front of his wheels.

"From a standing still position. When I move my body from over my heel to the ball of the foot. Not the toe.""

That's the problem - if you stop your body over the ball of the foot, then you've stopped the progress of the body.

To dance smoothly, your body will have to progress constantly - from heel, to ball, to toe, to BEYOND THE TOE.

If you keep your weight stationary over the ball of your standing foot until you moving foot is placed, then you aren't dancing smoothly - you are dancing STOP AND GO.
