Sink, Link, Turn

When the body sinks, the tailbone drops, the top of the body links to the bottom of the body. This is like train cars when two cars come together to connect. One car’s coupling lodges into the other’s by dropping down into the “lock”. This sinking allows the train cars to link. The link allows one section of the train to pull the other section(s). So too with the body. When linked one side of the body pulls the other which allows turning. One must sink before turning.
