To protect the body from harm and move well you need to know how things work together. Try this: bring your arms forward in front of you and rotate the arms so the little fingers point to the heavens. Now add the head forward and all together rotate all three back so you end up with hands to the back with thumbs up and head back. Repeat a few times and reverse the action so you know how you respond to each part moving in different ways and directions. Lie down and repeat this (you can lift yourself off the ground as you press the earth away with your elbows or hands if you can).
