There are only two scenes in the video below, and one of them demonstrates “Full Body Connected-ness”.
What does “Full Body Connected-ness” mean? The phrase refers to the ability of the entire human body to work as one large connected piece, as opposed to a large number of individual pieces working together with the inevitable disruptions of movement that would occur when trying to coordinate a large number of individual objects working together.
If you do not understand the point that is being made, re-watch the video and note how every movement of the girl’s body in the video happens at the same time. As if they were all being motivated from the same source.
