Orientation, manipulation, and timing are three facets of organization that have to come together for an action to be successful (doing the right thing in the right place at the right time).
You can create a new “manipulation” (the movement, considered as a configuration of the body in relation to itself) by altering the configuration of the starting place of the movement.
For instance, in the first rolling to sit lesson we altered the use of the arms at the beginning, feeling the difference it made to the ease of the movement and the participation of the core to let the elbows come towards the ceiling. There are lessons with similar folding/flexing the core movements where the arms are in the configuration of a donut-shaped circle around the head. How would that change things?
You could also vary the configuration of your head. What if your head were turned to the left or right, and in that turned position you lift, now your ear towards your knee?
What are some of the different configurations you could imagine for your legs, and how would that variation change the movement?
