This example demonstrates transition from eagle to eagle together with a basic opposing, over-elbow upper-body pattern. In an eagle (or "scissors") stance, the knee of the standing leg is nested directly into the hollow of the the opposite knee crossing over - as if they were pinned together. Squeeze both legs together so they operate as one, catching the floor with the toes of the crossed-over foot. The standing leg can be relaxed, the knee softened with the crossed-over leg supporting it. Note how the elastic cord is picked up from over the elbow inside the knee as it crosses over.
