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.
